In addition to the eight system fans, each power supply module installed provides an additional two non-redundant fans pulling air from inside the chassis out the back. 1.8 Chassis Security The SR2400 provides support for a lockable front bezel and a chassis intrusion switch. 1.9 Rack and Cabinet Mounting Options The Server Chassis SR2400 was designed to support 19" wide by up to 30" deep server cabinets. The chassis supports either of two rack mount options: A fixed mount relay rack / cabinet mount or a tool-less sliding rail kit. The fixed mount relay rack / cabinet mount kit can be configured to support both 2-post racks and 4-post cabinets. The tool-less sliding rail kit is used to mount the chassis into a standard (19" by up to 30" deep) EIA-310D compatible server cabinet. 1.10 Front Bezel Features The optional front bezel is made of molded plastic and uses a snap-on design. When installed, its design allows for maximum airflow. Revision 2.0 7 Intel order number C78845-001 Intel(R) Server Chassis SR2400 Product Overview Figure 10. Optional Front Bezel Separate front bezels are available to support systems that use either a Standard Control Panel or Intel Local Control Panel. When the Standard Control Panel is used, light pipes on the backside of the front bezel allow the system status LEDs to be monitored with the front bezel in the closed position. The front bezel lock is provided to prevent unauthorized access to hard drives, peripheral devices and the control panel. Figure 11. Front Bezel Supporting Standard Control Panel When the Intel Local Control Panel is used, the control panel module can be adjusted to extend further out from the chassis face to allow the LCD panel to protrude from the front bezel.

AC Power Subsystem AC Power Subsystem The AC power subsystem of the SR2400 consists of an integrated Power Distribution Board (PDB) and Power Module Enclosure assembly, with support for up to two 700 Watt AC power supply modules. The power subsystem can be configured to support a single module in a 1+0 non-redundant configuration, or dual modules in a 1+1 redundant power configuration. In a 1+1 configuration, a single failed power module can be hot-swapped with the system running. Either configuration will support up to a maximum of 700 Watts of power. This chapter provides technical details to the operation of the power supply module and power subsystem. 2.1 Mechanical Overview The drawing below displays the Power Distribution Board + Module Enclosure assembly FLANGE DETAILS TDB 106.0 +/- 0.5 MODULE 83.5 +/- 0.5 CAGE (100) 300 +/- 0.5 400 +/- 1.0 109.0 +/- 0.5 CAGE 40.0 +/- 0.5 MODULE MAX TBD Figure 13. Mechanical Drawing for Dual (1+1 configuration) PS enclosure with PDB 2.2 Power Module Population In single power module configurations, the power module must be inserted into the top slot of the power module enclosure. System and Power Supply thermals are not affected, however the non-operating slot must have the power supply blank installed. Revision 2.0 9 Intel order number C78845-001 Intel(R) Server Chassis SR2400 AC Power Subsystem 2.3 Handle and Retention Mechanism Each power supply module includes a handle allowing for module insertion to or removal from the module enclosure. Each module has a simple retention mechanism to hold the power module in place once it is inserted. This mechanism will withstand the specified platform mechanical shock and vibration requirements. The tab on the retention mechanism is colored Green to indicate it is a hot swap touch point. The latch mechanism is designed in such a way, so that it prevents inserting the module with the power cord plugged in. This will aid the hot swapping procedure. 2.4 Hot Swap Support Hot swapping a power supply module is the process of inserting and extracting a power supply module from an operating power system. During this process the output voltages shall remain within specified limits. Up to 2 power supply modules may be on a single AC line. The power supply module can be hot swapped by the following method: Extraction: on removal, the power cord is unplugged first, and then the power module is removed. This could occur in standby mode or power-on mode. Insertion: The module is inserted first and then the power cord is plugged in. The system and the supply will power on into Standby Mode or Power-On Mode. 2.5 Airflow Each power supply module incorporates two non-redundant 40mm fans for self cooling and is also used for partial system cooling. When installed in the system, the fans will provide approximately 15.5 CFM airflow at max load/ max temp in a 1+0 configuration, through the power supply and min 10CFM to the system. The air used to cool the power module is preheated from the system before being drawn through the power module. 2.6 Output Cable Harness A cable harness from the power distribution board is used to provide the system with the various power interconnects. The harness size, connectors, and pin outs are shown below. Listed or recognized component appliance wiring material (AVLV2), CN, Rated 85C Min, 300Vdc Min shall be used for all output wiring.

Revision 2.0 12 Intel order number C78845-001 Intel(R) Server Chassis SR2400 2.7.1 AC Power Subsystem AC Inlet Connector The AC input connector is an IEC 320 C-14 power inlet. This inlet is rated for 15A / 250VAC. 2.7.2 Efficiency The power supply combo (PS+PDB) has a minimum efficiency of 80% at maximum load and over 100-240VAC line voltage range to guarantee proper power supply cooling while mounted in the system. 2.7.3 AC Input Voltage Specification The power supply module operates within all specified limits over the following input voltage range, shown in the following table. Harmonic distortion of up to 10% of rated AC Input Voltage must not cause the power supply to go out of specified limits. The power supply shall power off on or after/below 75Vac 5Vac range. The power supply shall start up on or before/above 85VAC 4Vac. Application of an input voltage below 85VAC shall not cause damage to the power supply, including a fuse blow. Table 8. AC Input Rating PARAMETER Line Voltage (110) Line Voltage (220) Frequency 1 2 3 4 MIN RATED MAX 90Vrms 100-127 Vrms 140Vrms 180Vrms 47 Hz 200-240 Vrms 50/60Hz 264Vrms 63 Hz Start-up Vac 85Vac 4Vac - Power Off Vac 75Vac 5Vac - Max Rated Input AC Current Max Input AC Current 9.9 Arms1,3 8.9Arms 4 5.0 Arms2,3 4.5Arms 4 Maximum input current at low input voltage range shall be measured at 90Vac, at max load. Maximum input current at high input voltage range shall be measured at 180VAC, at max load. This is not to be used for determining agency input current markings. Maximum rated input current is measured at 100VAC and 200VAC. 2.7.4 AC Line Dropout / Holdup An AC line dropout is defined to be when the AC input drops to 0VAC at any phase of the AC line for any length of time. During an AC dropout of one cycle or less the power supply must meet dynamic voltage regulation requirements over the rated load. An AC line dropout of one cycle or less (20ms min) shall not cause any tripping of control signals or protection circuits (= 20ms holdup time requirement). If the AC dropout lasts longer than one cycle the power supply should recover and meet all turn-on requirements. The power supply must meet the AC dropout requirement over rated AC voltages, frequencies, and output loading conditions. Any dropout of the AC line shall not cause damage to the power supply. The min holdup time requirement is as follows: 20ms Min when tested under the following conditions: Max combined load = 600W, Line = 90Vac/47Hz, 18ms Min when tested under the following conditions: Max combined load = 650W, Line = 90Vac/47Hz, and 14ms Min when tested under the following conditions: Max combined load = 700W, Line = 90Vac/47Hz. Note: The B+ bulk cap voltage shall not exceed 400Vpk at any time. Revision 2.0 13 Intel order number C78845-001 Intel(R) Server Chassis SR2400 AC Power Subsystem 2.7.4.1 AC Line 5VSB Holdup The 5VSB output voltage should stay in regulation under its full load (static or dynamic) during an AC dropout of 70ms min (=5VSB holdup time) whether the power supply is in ON or OFF state (PSON asserted or de-asserted). 2.7.5 AC Line Fuse The power supply has a single line fuse, on the Line (Hot) wire of the AC input. The line fusing is acceptable for all safety agency requirements. The input fuse is a slow blow type. AC inrush current shall not cause the AC line fuse to blow under any conditions. All protection circuits in the power supply shall not cause the AC fuse to blow unless a component in the power supply has failed. This includes DC output load short conditions. 2.7.6 AC Inrush The peak AC inrush current shall be less than 40A peak for one-quarter of the AC cycle and less then the ratings of power supply's critical AC input components, including: input fuse, bulk caps, rectifiers, and surge limiting device. Also, a single inrush current disturbance It value MUST NOT exceed 20% of the It rating of the power supply's AC input fuse. The power supply must meet the AC inrush current requirements for any rated AC voltage, during turn-on at any phase of AC voltage, during a single cycle AC dropout condition as well as upon recovery after AC dropout of any duration, and over the specified temperature range Top, (includes hot and cold inrush). 2.7.7 AC Line Surge The power supply is tested with the system for immunity to AC Ring Wave and AC Unidirectional wave, both up to 2kV, per EN 55024:1998, EN 61000-4-5:1995 and ANSI C62.45: 1992. The pass criteria include: No unsafe operation is allowed under any condition; all power supply output voltage levels to stay within proper spec levels; No change in operating state or loss of data during and after the test profile; No component damage under any condition. 2.7.8 AC Line Transient Specification AC line transient conditions shall be defined as "sag" and "surge" conditions. "Sag" conditions are also commonly referred to as "brownout", these conditions will be defined as the AC line voltage dropping below nominal voltage conditions. "Surge" will be defined to refer to conditions when the AC line voltage rises above nominal voltage. The power supply shall meet the requirements under the following AC line sag and surge conditions. Table 9. AC Line Sag Transient Performance Duration Continuous 0 to 1 AC cycle > 1 AC cycle Sag 10% 95% AC Line Sag (10sec interval between each sagging) Operating AC Voltage Line Frequency Performance Criteria Nominal AC Voltage ranges 50/60Hz No loss of function or performance Nominal AC Voltage ranges 50/60Hz No loss of function or performance >30% Nominal AC Voltage ranges 50/60Hz Loss of function acceptable, self recoverable Revision 2.0 14 Intel order number C78845-001 Intel(R) Server Chassis SR2400 AC Power Subsystem Table 10.

The surge-withstand test must not produce damage to the power supply. The supply must meet surge-withstand test conditions under maximum and minimum DC-output load conditions. 2.7.10 AC Line Leakage Current The maximum leakage current to ground for each power supply module shall be not more then 3.5mA when tested at 240VAC. 2.8 DC Output Specification 2.8.1 Power Supply Mating Connector The power distribution board provides an edge connector slot for each of the supported power supply modules. Each power module has a keyed edge connector which is blind mated to the edge connector slot of the PDB. The following table provides the pinout for both the connector and slot. Table 11.

Power Module Edge Connector View Revision 2.0 16 Intel order number C78845-001 Intel(R) Server Chassis SR2400 2.8.2 AC Power Subsystem Grounding The ground of the pins of the PDB output connectors provides the power return path. The output connector ground pins are connected to safety ground (PDB enclosure). 2.8.3 Standby Output / Standby Mode The 5VSB output shall be present when an AC input greater than the power supply turn-on AC voltage is applied. Applying an external 5.25V to 5Vsb shall not cause the power supply to shut down or exceed operating limits. When the external voltage is removed the voltage shall return to the power supplies operating voltage without exceeding the dynamic voltage limits. 2.8.4 Remote Sense The PDB 12V to 3.3V and 5V converters use remote senses to regulate out voltage drops in the system for the +3.3V output. The remote sense output impedance to this DC/DC converter must be greater than 200. This is the value of the resistor connecting the remote sense to the output voltage internal to the DC/DC converter. Remote sense must be able to regulate out of up to 300mV drop on the +3.3V and 5V outputs. Also, the power supply ground return remote sense (ReturnS) passes through the PDB and the output harness to regulate out ground drops for its +12V and 5Vsb output voltages. The power supply uses remote sense (12VRS) to regulate out drops up to the 240VA protection circuit on the PDB. 2.8.5 Power Module Output Power / Currents The following table defines power and current ratings for the 700W continuous (810W pk) power supply in 1+0 or 1+1 redundant configurations. The combined output power of both outputs shall not exceed the rated output power. The power supply module must meet both static and dynamic voltage regulation requirements for the minimum loading conditions. Also, the power module shall be able to supply the listed peak currents and power for a minimum of 10 seconds. Outputs are not required to be peak loaded simultaneously. Table 12. Load Ratings MAX Load MIN DYNAMIC Load MIN STATIC Load PEAK Load (10 sec min) Max Output Power (continuous), see note 1 Peak Output Power (for 10s min), see note 2 +12V 58.0A 5.0A 1.0A 67.0A 12V x 58A = 696W max 12V x 67A = 804W pk +5Vsb 2.0A 0.1A 0A 2.5A 5V x 2A = 10W max 5V x 2.5A = 12.5W pk Note: 1. In reality, at max load the 12V output voltage is allowed to sag to -3%, which is 11.64V; so the actual max power will then be: 11.64V x 58A = 675.12 W, and the same applies for 5VSB: 4.85Vx2A=9.7W; so total max continuous Power = 675.12+9.7=684.82W 2. In reality, at peak load the 12V output voltage is allowed to sag to -3%, which is 11.64V; so the actual peak power will then be: 11.64V x 67A = 780 W; and the same applies to 5VSB: 4.85Vx2.5A=12.125W. The total peak power = 792 W pk. Revision 2.0 17 Intel order number C78845-001 Intel(R) Server Chassis SR2400 AC Power Subsystem 2.8.6 +12V Outputs Load Requirements This section describes the +12V output power requirements from the power distribution board with a either single or dual ERP700W power supply module plugged into the input of the power distribution board. Note: The combined total power limit for all outputs is 700W max. Table 13. +12V Outputs Load Ratings +12V1/2/3/4 combined output limit = 48A / 60A pk max MAX Load MIN Static / Dynamic Load Peak load Max Output Power, see note 1 2.8.7 +12V1 12.5A 0.5 15A 12 x12.5 =150W +12V2 12.5A 0.5 15A 12 x12.5 =150W +12V3 14A 1.5A 17A 12V x14A =168W +12V4 10A 1.5A 16A 12V x10A =120W DC/DC Converters Loading The following table defines power and current ratings of 3 DC/DC converters located on the PDB, each powered from the +12V rail. The 3 converters must meet both static and dynamic voltage regulation requirements for the minimum and maximum loading conditions. Note: 3.3V / 5V combined power limit: 140W max. Table 14. DC/DC Converters Load Ratings MAX Load MIN Static / Dynamic Load Max Output Power, see note 1 +12VDC Input DC/DC Converters +3.3V Converter +5V Converter -12V Converter 24.0A 24.0A 0.5A 0.5A 0.5A 0A 3.3x24=79.2W 5x24=120W 0.5x12=6W Notes: 1. The straight sum of the 3 max powers = 205.2W, but considering the 3.3/5V power limit, it may be 140W +6W = 146W max combined power. In reality, at max load, each output voltage is allowed to sag to Vmin, so the actual each max power will then be: for 3.3V: 3.2Vx24A = 76.8W, for 5V: 4.8Vx24A=115.2W; and for -12V: 11.4Vx0.5A=5.7W. 2.8.8 DC/DC Converters Voltage Regulation The DC/DC converters' output voltages must stay within the following voltage limits when operating at steady state and dynamic loading conditions. All outputs are measured with reference to the return remote sense signal (ReturnS). The 3.3V and 5V outputs are measured at the remote sense point, all other voltages measured at the output harness connectors. Table 15.

A minimum of: 45 degrees phase margin and -10dB-gain margin is required. Closed-loop stability must be ensured at the maximum and minimum loads as applicable. 2.8.12 Common Mode Noise The Common Mode noise on any output shall not exceed 350mV pk-pk over the frequency band of 10Hz to 20MHz. 1. The measurement shall be made across a 100 resistor between each of DC outputs, including ground,at the DC power connector and chassis ground (power subsystem enclosure). 2. The test set-up shall use a FET probe such as Tektronix model P6046 or equivalent. 2.8.13 DC/DC Converters Ripple / Noise The maximum allowed ripple/noise output of each DC/DC Converter is defined in the following table. This is measured over a bandwidth of 0Hz to 20MHz at the PDB output connectors. A 10F tantalum capacitor in parallel with a 0.1F ceramic capacitor are placed at the point of measurement.

Turn On/Off Timing (Power Supply/PDB combo Signals) 2.8.15 Residual Voltage Immunity in Standby Mode Each DC/DC converter is immune to any residual voltage placed on its respective output (typically a leakage voltage through the system from standby output) up to 1000mV. This residual voltage shall not have any adverse effect on each DC/DC converter, such as: no additional power dissipation or over-stressing / over-heating any internal components or adversely affecting the turn-on performance (no protection circuits tripping during turn on). While in Stand-by mode, at no load condition, the residual voltage on each DC/DC converter output shall not exceed 100mV. 2.9 Protection Circuits Protection circuits inside the PDB and the power supply module shall cause either the power supply's main +12V output to shutdown, which in turn shuts down the other 3 outputs on the PDB or first shut down any of the 3 outputs on the PDB, which in turn also shuts down the entire power supply combo. If the power supply latches off due to a protection circuit tripping, an AC cycle OFF for 15sec min and a PSON# cycle HIGH for 1sec shall be able to reset the power supply and the PDB. 2.9.1 Over-Current Protection (OCP) Each DC/DC converter output on PDB shall have individual OCP protection circuits. The PS+PDB combo shall shutdown and latch off after an over current condition occurs. This latch shall be cleared by toggling the PSON# signal or by an AC power interruption. The following table provides the over current limits. The values are measured at the PDB harness connectors. The DC/DC converters shall not be damaged from repeated power cycling in this condition. Also, the +12V output from the power supply is divided on the PDB into 4 channels and each is limited to 240VA of power. There shall be current sensors and limit circuits to shut down the entire PS+PDB combo if the limit is exceeded. The limits are listed below.

If the current limits are exceeded, the power supply module shall shutdown and latch off. The latch will be cleared by toggling the PSON# signal or by an AC power interruption. The power supply shall not be damaged from repeated power cycling in this condition. 5VSB shall be protected under over-current or shorted conditions, so that no damage can occur to the power supply.

In an OTP condition the PSU will shutdown. When the power supply temperature drops to within specified limits, the power supply shall restore power automatically, while the 5VSB remains always on. The OTP trip level shall have a minimum of 4C of ambient temperature hysteresis, so that the power supply will not oscillate on and off due to temperature recovery condition. The power supply shall alert the system of the OTP condition via the power supply FAIL signal and the PWR LED. 2.10 SMBus Monitoring Interface The PS+PDB combo provides a monitoring interface to the system over a server management bus. The SMBus pull-ups are located on the motherboard. This shall provide power monitoring, failure conditions, warning conditions, and FRU data. Two pins have been reserved on the connector to provide this information. One pin is the Serial Clock (PSM Clock). The second pin is used for Serial Data (PSM Data). Both pins are bidirectional and are used to form a serial I2C bus. For redundant power supplies: The device(s) in the power supply shall be located at an address(s) determined by address pins A0 and A1. The circuits inside the power supply shall be powered from the 5VSB bus and grounded to ReturnS (remote sense return). For redundant power supplies the device(s) shall be powered from the system side of the OR-ing device. The EEPROM for FRU data in each power supply is hard wired to allow writing data to the device. There are two usage modes depending on the system. The system shall control the usage mode by setting the Usage Mode bit. * Default Mode: In this mode, the LEDs and registers must automatically clear when a warning event has occurred, because there is no software, BIOS, or other agent that will access the power supply via SMBus to do any clearing. * Intelligent Mode: A system management controller or BIOS agent exists that can read and clear status. In this mode, the LEDs and registers should latch when a warning event occurs so that the system and user can read their status before it changes during transient events. There should also be a mechanism to allow the system management or BIOS to `force' the LED states in order to identify which power supply should be replaced. Critical events will cause the power supply to shutdown and latch the LED and SMBAlert signal no matter what mode the power supply is in: "default mode" or "intelligent mode". Warning events latch the LED and SMBAlert signal when in "intelligent" mode. If in the "default mode", the LED and SMBAlert signal will de-assert as soon as the condition driving the event clears. For redundant 1+1 configuration: If the power supply has failed due to an open AC fuse and therefore has no input power, the LED and SMBAlert signal must still operate with another operating power supply in parallel. Therefore, these circuits must be powered from the output side of the 5VSB OR-ing device. Revision 2.0 23 Intel order number C78845-001 Intel(R) Server Chassis SR2400 AC Power Subsystem For non-redundant 1+0 configuration: If the power supply fails due to over temperature shutdown, over current shutdown, over power shutdown, or fan failure: the LED, SMBAlert signal, and critical event registers, shall still operate correctly. If the supply fails due to loss of AC or open fuse, then the LED and signals will have no power and therefore will not operate. 2.10.1 Hot Plug I2C Requirements Since the redundant power supplies will be asynchronously installed and powered-on in a system, the SMBus devices on the supply need to be tolerant of joining the SMBus in the middle of a SMBus transaction and ignore bus activity after being powered on until a valid start of transaction is seen. 2.10.2 Power Supply Failure Communication Here, there is no failure signal from the power supply to the PDB. The SMBus Alert signal will assert if something (critical or warning) is going wrong with the power supply. Then the system will need to poll the power supply via the SMBus to see what type of warning or failure condition has occurred. 2.10.3 LED Control There shall be two bits to control the power supply LEDs. One bit forces the Amber LED ON and Green LED OFF. Another bit forces the Amber LED to blink at 1Hz and the Green LED OFF. Writing a 1b to these bits forces the LEDs to these states. Writing a 0b allows control of the LED back to the power supply. There will be a single bi-color LED to indicate power supply status. The LED operation is defined below. Table 24. LED Indicators Power Supply Condition No AC power to all power supplies No AC power to this PSU only (for 1+1 configuration) or Power supply critical event causing a shutdown: failure, fuse blown (1+1 only), OCP, OVP, Fan Failed Power supply warning events where the power supply continues to operate: high temp, high power, high current, slow fan. AC present / Only 5VSB on (PS Off) Output ON and OK Bi-Color LED OFF AMBER 1Hz Blink AMBER 1Hz Blink GREEN GREEN The LED is visible on the rear panel of each installed power supply module. There shall be bits that allow the LED state to be forced via SMBus. The following capabilities are required: * * * Force Amber ON for failure conditions. Force Amber 1Hz Blink for warning conditions. No Force (LED state follows power supply present state) The power-on default should be `No Force'. The default is restored whenever PSON transitions to assert. Revision 2.0 24 Intel order number C78845-001 Intel(R) Server Chassis SR2400 3. DC Power Subsystem DC Power Subsystem The DC power subsystem of the SR2400 consists of a Power Distribution Board (PDB) and up to two 600 Watt DC power supply modules. The power subsystem can be configured to support a single module in a 1+0 non-redundant configuration, or dual modules in a 1+1 redundant power configuration. In a 1+1 configuration, a single failed power module can be hot-swapped with the system running. Either configuration will support up to a maximum of 600 Watts of power. The PDB and the 600 Watt DC power supply module are identical to the ones used in Intel(R) Carrier Grade Server TIGI2U. For technical details, refer to TIGI2U PDB specification and TIGI2U DC Power Supply specification. Revision 2.0 25 Intel order number C78845-001 Intel(R) Server Chassis SR2400 Cooling Subsystem 4. Cooling Subsystem A 4+4 system fan module, the power supply fans, air baffle, CPU air duct and drive bay population are the necessary components to provide the system with the necessary air flow and air pressure to maintain the system's thermals when operating at or below maximum specified thermal limits. See Table 70. System Environmental Limits. 4.1 4+4 System Fan Module The primary airflow for the system is provided by a removable plastic fan housing which secures up to eight 60mm x 38mm multi-speed fans. Eight 6-pin connectors on the fan distribution board provide each fan with power and tachometer output, allowing it to be monitored independently by server management software. The following table provides the pin-out for the connectors on each fan and corresponding header on the fan distribution board. Table 25.

Fan Distribution Board Layout There are two fan control connectors located on the fan distribution board. The 24-pin connector, found on the side of the board closest to the baseboard, is cabled to a matching connector on the baseboard. This connector provides power and fan speed control to the first four fans and provides management pins for all eight fans. The 2x5 connector found on the opposite edge of the board is used to provide power and fan speed control for the optional remaining bank of four fans and is cabled to either the SCSI or SATA backplane. The following tables provide the pinout for each of the two fan control connectors.

However, the fans are not hot swappable. The server must be turned off before a fan can be replaced. Each fan within the module is capable of supporting multiple speeds. If the internal ambient temperature of the system exceeds the value programmed into the thermal sensor data record (SDR), the Baseboard Management Controller (BMC) firmware will increase the speed for all the fans within fan module. Revision 2.0 27 Intel order number C78845-001 Intel(R) Server Chassis SR2400 Cooling Subsystem * * Each fan connector within the module supplies a tachometer signal allowing for baseboard management to monitor the status of each fan. If one of the fans should fail, the remaining fans will increase their rotation and attempt to maintain the thermal requirements of the system. Each fan within the module is equipped with a failure LED. In the event of a fan failure, the failure LED on the failing fan can be illuminated by baseboard management. Note: the fan failure LED functionality is only supported when the system is configured with an Intel(R) Management Module (IMM). Fault LED Air Flow Default Fan Bank Optional Fan Bank Power Connect from Backplane Figure 17. Fan Module Assembly 4.2 Fan Redundancy By default, the Server Chassis SR2400 comes with four system fans. Under normal operating conditions, these fans provide enough cooling for the system but offer no fan redundancy. If a fan should fail, the system may heat up beyond its thermal limits causing the system to shutdown. The fan module is designed to support an additional four system fans, supporting a 4+4 fan configuration. In systems configured with an Intel Management Module, fan redundancy is supported in the event of a fan failure. Should a fan fail, the remaining seven system fans will speed up providing adequate cooling to the system. This redundancy model will allow for a single fan failure only. Should a second fan fail, fan redundancy is lost and the system may heat up beyond its thermal limits. A failed fan should be replaced as soon as possible. With no Intel Management Module installed, a 4+4 fan configuration can be used but is not recommended due to increased acoustics. Fans will operate faster with little cooling benefit. In this configuration there is no fan redundancy. Should any of the eight fans fail, the system may heat up beyond its thermal limits. Revision 2.0 28 Intel order number C78845-001 Intel(R) Server Chassis SR2400 4.3 Cooling Subsystem Air Flow Support To control airflow within the system, the Server Chassis SR2400 uses a combination air baffle and CPU Air Duct to isolate and direct airflow to three critical areas or zones: the Power Supply Zone, the Full Height PCI Zone, and the CPU/Memory/Low Profile PCI Zone. 4.3.1 Power Supply Zone An air baffle is used to isolate the air flow of the main system board zones from the zone directly behind the power supply. As the power supply fans pull pre-heated air through the power supply from inside the chassis, the zone behind it must remain as cool as possible by drawing air from the leftmost drive bays only. 4.3.2 Full Height Riser Zone The Full Height Riser zone is the area between the power supply and the full height riser card of the riser assembly. The air flow through this area is generated by FAN4 of the fan module in a non-redundant fan configuration. In a redundant fan configuration, the air flow for this zone is provided by FAN4 and FAN8. Air is drawn from the drive bay area through the fan and pushed out of the system through ventilation holes the back side of the chassis. 4.3.3 CPU / Memory / Low Profile PCI Zone The CPU / Memory / Low Profile PCI zone is the area between the Low Profile Riser card of the riser assembly and the right chassis wall. In a non-redundant fan configuration, the air flow for this zone is generated by system fans FAN1, FAN2, and FAN3 of the fan module. In a redundant fan configuration, the air flow for this zone is provided by system fans FAN1 and FAN5, FAN2 and FAN6, and FAN3 and FAN7. Air is drawn from the drive bay area, through the fans, directed through the CPU Air Duct, and out through ventilation holes on both the back wall and rear side wall of the chassis. The CPU Air duct is used to direct air flow through the processor heat sinks for both single and dual processor configurations. For single processor configurations, a flexible air baffle is attached to the air duct as shown in the following diagram. Figure 18. CPU Air Duct with Air Baffle Operating a single processor configuration without the air baffle installed will result in the processor over heating and may cause the system to shutdown. Revision 2.0 29 Intel order number C78845-001 Intel(R) Server Chassis SR2400 Cooling Subsystem 4.4 Drive Bay Population To maintain the proper air pressure within the system, all hard drive bays must be populated with either a hard drive, or drive blank.

Peripheral and Hard Drive Support Peripheral and Hard Drive Support The SR2400 server chassis can be configured to support several different types of hard drive and peripheral configurations. The chassis can support up to five hard disk drives, a slim-line optical or floppy drive, and an optional 6th hard drive or tape drive. 5.1 Slimline Drive Bay The chassis provides a slim-line drive bay that can be configured for either CDROM, DVD, or Floppy drives with or without the presence of a backplane. The peripheral drives are mounted on a tool-less tray which allows for easy installation into and removal from the chassis. Once inserted into the chassis, the assembly locks into place. For removal, the chassis top cover must be removed and the locking latch disengaged. 5.1.1 Floppy Drive Support A slim-line floppy drive can be supported in multiple system configurations. 5.1.1.1 Floppy Drive Use with Installed Backplane When either a SCSI or SATA backplane is installed, the slim-line floppy drive is cabled directly to a connector on the backplane.

For hot swap drive configurations, 3.5" x 1" hard disk drives are mounted to hot swap drive trays for easy insertion to or extraction from the drive bay. For cabled drive configurations, the SATA hard drives are mounted to a fixed mount drive tray which is only removable when detached from inside the chassis. 5.2.1 Hot Swap Drive Trays In a hot swap configuration, each hard drive must be mounted to a hot swap drive tray, making insertion and extraction of the drive from the chassis very simple. Each drive tray has its own dual purpose latching mechanism which is used to both insert/extract drives from the chassis and lock the tray in place. Each drive tray supports a light pipe providing a drive status indicator, located on the backplane, to be viewable from the front of the chassis. Note: Depending on the controller used, SATA hard disk drives may not report errors using the drive's status indicator.

SATA Backplane Functional Block Diagram 5.4.2.1 Enclosure Management Controller * The QLogic GEM424 is an enclosure management controller for the SATA backplane and monitors various aspects of a storage enclosure. The chip provides in-band SAF-TE and SES management through the SATA Host I2C interface. The GEM424 also supports the IPMI specification by providing management data to a baseboard management controller through the IPMB via the 100-pin connector. The GEM424 comes in a 80-pin Thin Quad Flat Pack (TQFP) package and operates from 3.3V and input clock frequency of 20MHz. It has general input and output pins that allow for customization. These GPIOs are used for hardware drive detection and driving FAULT and ACTIVITY LEDs. 5.4.2.1.1 SATA Interface The GEM424 implements SAF-TE over the HBA I2C interface, and supports the following SAFTE Command Set: * * * * * * Read Enclosure Configuration Read Enclosure Status Red Device Slot Status Read Global Flags Write Device Slot Status Perform Slot Operation 5.4.2.1.2 I2C Serial Bus Interface The GEM424 supports two independent I2C interface ports with bus speeds of up to 400Kbits. The I2C core incorporates 8-bit FIFOs for data transfer buffering. The I2C bus supports the National* LM75 or equivalent I2C -based temperature sensors. This enables actual temperature value readings to be returned to the host. The Intelligent Platform Management Bus (IPMB) is supported through I2C port 0. The figure below provides a block diagram of I2C bus connection implemented on the SR2400 2U SATA HSBP.

SATA Backplane I2C Block Diagram 5.4.2.2 Temperature Sensor The SATA HSBP uses a National(R) LM75 or equivalent temperature sensor with overtemperature detector. The host can query the LM75 at any time to read the temperature. The temperature sensor has the I2C address of 0x90h on GEM424's Port 0. 5.4.2.3 Serial EEPROM The SATA HSBP uses an Atmel* 24C02 or equivalent serial EEPROM for storing the FRU information. The 24C02 provides 2048 bits of serial electrically erasable and programmable read-only The serial EEPROM has the I2C addres of 0xA6h on GEM424's Port 1. 5.4.2.4 External Memory Device The SATA HSBP uses non-volatile 32K and 64K Serial EEPROM devices for Boot and RunTime/Configuration code storage respectively. These devices reside on the GEM424's private I2C bus. The SEEPROMs operate off the 5.0V rail and are housed in 8-pin SOIC packages 5.4.3 LEDs The SATA HSBP contains a green ACTIVITY LED and an amber FAULT LED for each of the six drive connectors. The ACTIVITY LED is driven by both the GEM424 controller and SATA drives themselves using pin 11 on the connector. Therefore systems with newer SATA drives supporting pin 11 can support drive activity regardless of what SATA controller is used. The FAULT LED is driven by the GEM424 controller whenever an error condition is detected. Activity and Fault LED functions are only available when a SATA host controller that supports the SAF-TE protocol over I2C is connected to the SR2400 2U SATA HSBP via the SATA Host I2C connector, J7M3.

Standard Control Panel Standard Control Panel The standard control panel supports several push buttons and status LEDs, along with USB and video ports to centralize system control, monitoring, and accessibility to within a common compact design. The control panel assembly comes pre-assembled and is modular in design. The control panel assembly module slides into a predefined slot on the front of the chassis. Once installed, communication to the baseboard can be achieved by either attaching a 50-pin cable to a hotswap backplane, or if cabled drives are used, can be connected directly to the baseboard. In addition, a USB cable is routed to a USB port on the baseboard. Figure 31. Standard Control Panel Assembly Module 6.1 Control Panel Buttons The standard control panel assembly houses several system control buttons. Each of their functions is listed in the table below. Figure 32. Control Panel Buttons Revision 2.0 57 Intel order number C78845-001 Intel(R) Server Chassis SR2400 Standard Control Panel Table 56. Contol Button and Intrusion Switch Functions Reference B Feature Power / Sleep Button ID Button C D Reset Button NMI Button A 6.2 Function Toggles the system power on/off. This button also functions as a Sleep Button if enabled by an ACPI-compliant operating system. Toggles the front panel ID LED and the baseboard ID LED on/off. The baseboard ID LED is visible through the rear of the chassis and allows you to locate the server you're working on from behind a rack of servers. Reboots and initializes the system. Pressing the recessed button with a paper clip or pin puts the server in a halt state for diagnostic purposes and allows you to issue a non-maskable interrupt. After issuing the interrupt, a memory download can be performed to determine the cause of the problem. Control Panel LED Indicators The control panel houses six LEDs, which are viewable with or without the front bezel to display the system's operating state. NIC1 and NIC2 Activity LEDs Power and Sleep LED System Status LED Hard Drive Activity LED System Identify LED Figure 33.

The amber status takes precedence over the green status. When the amber LED is on or blinking, the green LED is off. Also off when the system is powered off (S4/S5) or in a sleep state (S1). The power LED sleep indication is maintained on standby by the chipset. If the system is powered down without going through BIOS, the LED state in effect at the time of power off will be restored when the system is powered on until the BIOS clears it. If the system is not powered down normally, it is possible that the Power LED will be blinking at the same time that the system status LED is off due to a failure or configuration change that prevents the BIOS from running. The current limiting resistors for the power LED, the system fault LED, and the NIC LEDs are located on the baseboard. 6.2.1 Power / Sleep LED Table 58.

Blink rate is ~ 1Hz with at 50% duty cycle. 6.2.2 System Status LED Note: Some of the following status conditions may or may not be reported if the system is not configured with an Intel Management Module. Refer to the baseboard technical product specification for details. 6.2.2.1 Critical Conditions A critical condition is any critical or non-recoverable threshold crossing associated with the following events: * * * * * * Temperature, voltage, or fan critical threshold crossing. Power subsystem failure. The BMC asserts this failure whenever it detects a power control fault (e.g., the BMC detects that the system power is remaining ON even though the BMC has deserted the signal to turn off power to the system. A hot-swap backplane would use the Set Fault Indication command to indicate when one or more of the drive fault status LEDs are asserted on the hot-swap backplane. The system is unable to power up due to incorrectly installed processor(s), or processor incompatibility. Satellite controller sends a critical or non-recoverable state, via the Set Fault Indication command to the BMC. Critical event logging errors, including: System Memory Uncorrectable ECC error, and fatal / uncorrectable bus errors such as PCI SERR and PERR. Revision 2.0 59 Intel order number C78845-001 Intel(R) Server Chassis SR2400 Standard Control Panel 6.2.2.2 Non-Critical Conditions A non-critical condition is threshold crossing associated with the following events: * * * * 6.2.2.3 Temperature, voltage, or fan non-critical threshold crossing Chassis intrusion Satellite controller sends a non-critical state, via the Set Fault Indication command, to the BMC. Set Fault Indication command from system BIOS. The BIOS may use the Set Fault Indication command to indicate additional `non-critical' status such as a system memory or CPU configuration changes. Degraded Conditions A degraded condition is associated with the following events: * * * 6.2.3 Non-redundant power supply operation. This applies only when the BMC is configured for a redundant power subsystem. One or more processors are disabled by Fault Reliant Booting (FRB) or BIOS. BIOS has disabled or mapped out some of the system memory. Drive Activity LED The drive activity LED on the front panel indicates drive activity from the onboard hard disk controllers. The server board SE7520JR2 also provides a header giving access to this LED for add-in controllers. 6.2.4 System Identification LED The blue system identification LED is used to help identify a system for servicing. This is especially useful when the system is installed when in a high density rack or cabinet that is populated with several similar systems. The system ID LED will blink when the System ID button on the control panel is pressed or it can be illuminated remotely through server management software. 6.3 Control Panel Connectors The control panel has two external I/O connectors: * * One USB port One VGA video port The following tables provide the pin-outs for each connectors.

The video source is the same for both connectors and is switched between the two, with the control panel having priority over the rear video. This provides for easy front accessibility to the server. 6.4 Internal Control Panel Assembly Headers The Control Panel interface board has two internal headers: A 50-pin header provides control and status information to/from the server board. Using a 50-pin flat cable, the header can either be connected to a matching connector on a hot swap backplane or, in cabled drive configurations, can be connected to a matching connector on the baseboard. A 10-pin header is used to provide USB support to the control panel. The round 10-pin cable is routed from the control panel assembly to a matching connector on the baseboard.

PCI Riser Cards and Assembly The Server Chassis SR2400 supports different riser card options depending on the add-in card configuration desired. The riser assembly for the Server Chassis SR2400 is tool-less. Stand-offs on the bracket allow the riser cards to slide onto the assembly where a latching mechanism than holds each riser in place. Holding down the latch releases the risers for easy removal. When re-inserting the riser assembly into the chassis, tabs on the back of the assembly should be aligned with slots on the back edge of the chassis. The tabs fit into the slots securing the riser assembly to the chassis when the top cover is in place. The riser assembly provides two extraction levers to assist with riser assembly removal from the riser slots. There are 4 different riser card options offered: o Low profile PCI-X - This riser card is capable of supporting up to three low profile 66/100 MHz PCI-X cards o Full height PCI-X - This riser card is capable of supporting up to three full height/full length 66/100 MHz PCI-X cards o Full height PCI-X (active) - This riser card is capable of supporting two 133 MHz PCI-X cards and one 66/100 MHz PCI-X card. o Full height PCI-Express - This riser card is capable of supporting two X4 PCI-Express cards and one 66/100 PCI-X card.
