1. INTRODUCTION

Distribution Patch Panel Enclosures 559542–[ ]

(24–port), 559614–[ ] (48–port), shown in Figure 1,

and 559552–[ ] (72–port) are used for housing

singlemode and multimode fiber optic connections.

The enclosure fits into standard 483–mm [19.0–in.] or

584–mm [23.0–in.] Electronic Industries Alliance (EIA)

racks only. Read these instructions thoroughly before

starting installation.

Dimensions in this instruction sheet are in

millimeters [with inches in brackets]. Figures are

not drawn to scale.

Reasons for reissue of this instruction sheet are

provided in Section 5, REVISION SUMMARY.

2. DESCRIPTION

(Figure 1)

The enclosure consists of a chassis and interchange–

able front cover and back cover. The enclosure

features a fixed patch panel, and two cutouts on each

side for cable entrance and exit. The patch panel

holds “snap–in” adapter plates and is marked by

alphabet for connector identification.

Inside the front of the enclosure are three split fiber

saddle rings; inside the back of the enclosure are two

cable clamp brackets, two split fiber saddle rings, and

a lug (mounted onto the floor of the chassis). The

cable clamp brackets are used for securing the

breakout cable to the enclosure, and the lug is used

for securing the central strength member (if present)

to the enclosure. Cable routing within the enclosure is

facilitated by the fiber saddles.

Two universal mounting brackets and four 12–24

UNF–2A pan head screws are included for mounting

in the rack. Also included are two label cards and a

danger label.

3. INSTALLATION

3.1. Mounting the Enclosure

ALWAYS use safe lifting techniques. NEVER lift

more than you can manage comfortably. Lifting

guidelines are available from the Occupational

Safety and Health Administration (OSHA).

1. Unlatch and open the front cover, and set aside.

Unlatch and open the back cover, and set aside.

The covers are not attached to the enclosure.

2. The enclosure is assembled for mounting in a

483 [19.0] rack; mount the enclosure in the rack.

See Figure 2. For a 584 [23.0] rack, remove the

screws securing the brackets to the enclosure.

Turn the brackets so that the long leg of the “L” is

protruding, and secure the brackets to the

enclosure using the screws. Mount the enclosure

in the rack. See Figure 2.

3.2. Preparing the Cable

ALWAYS wear eye protection when working with

optical fibers. NEVER look into the end of a

terminated or unterminated fiber. Laser radiation

is invisible but can damage eye tissue. NEVER

eat, drink, or smoke when working with fibers.

This could lead to ingestion of fiber particles.

BE VERY CAREFUL to dispose of fiber ends

properly. The fibers create slivers that can easily

puncture the skin and cause irritation.

1. Strip the outer sheathing of the breakout cable,

and if present, cut the central strength member to

the dimensions shown in Figure 3.

2. Trim the strength members close to the end of

the outer sheathing. Wipe the fibers with a clean,

dry cloth. If necessary, use an alcohol pad to

remove any oily residue from the fibers.

3.3. Installing the Adapter Plate onto the Patch Panel

1. Position the adapter plate over the front of the

patch panel so that the split end of the lock pins

align with the holes in the patch panel. Push the

lock pins into the holes until the adapter plate is

secure. See Figure 4.

2. Follow same procedure for remaining adapter

plates.

3.4. Routing the Cable

Use the following guidelines when installing cable and

routing the fiber in the enclosure. Whatever method is

used, make sure that it not only meets the application

needs, but also conforms to local codes and

standards:

Allow enough fiber in the enclosure for routing

Coil excess fiber around split fiber saddle rings

Tyco Electronics Corporation

Keep bend radii of cable and fiber as large as

possible (always follow manufacturer’s

minimum bend radius)

DO NOT exceed minimum bend radii for the

cable or fiber. ALWAYS avoid placing fiber under

tension or torsion.

These instructions reflect a typical installation

where cable or fiber is routed through only one side of

the enclosure, however cable or fiber can be routed

through both sides of the enclosure. Follow the same

procedure for both.

A. Securing the Breakout Cable

1. Route the cable through the cutout in the back

of the enclosure and closest to the adapter plate to

be used. Make sure that at least 2000 [79.0] of

fiber is inside the enclosure. Lay the cable over the

cable clamp bracket, and secure the cable to the

bracket using cable ties. See Figure 5.

2. If a central strength member is present, loosen

the mounting screw in the lug, and pivot the lug so

that the opening faces the cable. Tighten the

Member Secured to

Lug (See Detail)

mounting screw. Loosen the setscrew, and insert

the central strength member into the lug so that the

central strength member butts against the terminal.

Tighten the setscrew firmly. See Figure 5.

B. Routing Fiber

1. Separate the first group of 12 fibers to be

located on the first two adapter plates. Terminate

these fibers onto connectors according to the

instructions provided with the connectors.

2. Dress the fiber around the split fiber saddle ring

at the opposite side of the enclosure. Join the

connectors to the coupling bushings at the back of

the adapter plate. See Figure 6, Detail A.

3. Separate the next group of 12 fibers to be

located on the next two adapter plates. Terminate

these fibers onto connectors according to the

instructions provided with the connectors.

4. Dress the fiber around the other split fiber

saddle ring. Join the connectors to the coupling

bushings at the back of the adapter plate. See

Figure 6, Detail B.

5. If applicable, continue separating groups of 12

fibers and terminating the fibers until the adapter

plates are completely loaded.

6. If necessary, fiber can be routed through the

back of the enclosure and joined to the front the

adapter plate, or routed through the front of the

enclosure and joined to the back of the adapter

plate. In this case, route the fiber through either

opening between the side of the enclosure and the

patch panel. Refer to Figure 7.

C. Routing Jumper Cable

1. Route the jumper cable through the cutout

(either or both sides) in the front of the enclosure.

2. Dress the cable through the split fiber saddle

rings, and join the connectors to the coupling

bushings at the front of the adapter plate. See

Figure 8.

3.5. Inspecting and Closing the Enclosure

1. Record connector positions using the label

cards, then install one label card onto the front

cover and one label onto the back cover.

Some enclosures contain a label holder installed

onto the front of the enclosure.

2. Install the danger label onto the front cover.

3. Inspect installation according to the following:

— enclosure is secure to rack (pan head screws

are tight)

— cable is not nicked or broken

— cable is secured to cable clamp bracket

— center strength member (if present) is fully

inserted into lug and setscrew is tight

— there are no sharp bends or kinks in the

fibers

— there are no fibers under tension

— connectors are undamaged

— all connectors are fully joined to coupling

bushings

4. Install the front and back covers onto the

enclosure, close the covers, and inspect closing

according to the following:

— covers are fully latched

— no cable or fibers are pinched in covers
