Redundant Power System
The SuperStack 3
Advanced
Redundant Power
System provides
redundant power
supplies for all
SuperStack units,
ensuring high
availability.
The 3Com® SuperStack®3 Advanced
Redundant Power System provides
crucial protection for SuperStack
components, ensuring that businesses
experience no loss of data or connec-
tivity during power interruptions or
failures. This modular system
incorporates eight slots that accept one
of four varieties of hot-swappable
power modules, each capable of
supporting one SuperStack device.
For extra protection, two modules can
be connected using a Y-cable to create a
completely redundant system powering
a single SuperStack device. If one
module fails, the second takes over
without disrupting other devices.
Modules can be installed together in
various combinations within a single
SuperStack 3 Advanced Redundant
Power System chassis, depending on
the power consumption of SuperStack 3
components being protected. The
chassis can support up to eight Type 1
60W modules, four Type 1 100W or
Type 2A 100W modules, or two Type 3
325W modules.
With the SuperStack 3 Advanced
Redundant Power System, businesses
enjoy peace of mind knowing that their
network remains trouble free and
operational at all times. Plus, they
receive added assurance with the
knowledge that the system is backed by
the proven reliability of 3Com and a
lifetime limited warranty.
Feature Benefits
High availability Redundant power supplies, with hot-
swappable power modules provide
high availability operation.
Modular, hot-swappable solution Provides extra assurance that the
network will remain operational
during power interruptions and
failures.
Complete redundancy Two ARPS modules can be connected
using a Y-cable, providing total
resilience.
Dual phase mains power Additional resilience can be achieved
by using mains from different phase
supplies or by using an uninterruptible
power system (UPS) input as a back
up to the primary mains input.
Reliable back-up The SuperStack 3 Advanced
Redundant Power System ensures
reliable network operation even in
the unlikely event of a power supply
failure.

When there is a switch unit power supply failure and a single ARPS chassis
and related modules are utilized, the switch unit will experience a typical 5-20
second delay before normal operation is resumed.
For completely uninterrupted operation, two ARPS chassis and modules must
be used in conjunction with a Y cable, and the switch unit be powered
entirely from two ARPS Chassis. With this configuration, no reset period will
be experienced should an ARPS Chassis or mains supply fail.
The SuperStack 3 Advanced Redundant Power System can support any
combination of the above modules, up to its rated maximum power of 480
Watts. An exception can be made in the case of the Type 3 module, whereby
two of these modules can be installed into a single chassis.
