1. INTRODUCTION
2U MPO Secure Rack-Mounted Enclosure Assembly
1553761-1 is used to house and manage MPO Secure
fiber optic connections. The enclosure fits into a
standard 483-mm [19.0-in.] Electronic Industries
Alliance (EIA) rack or cabinet.
Dimensions in this instruction sheet are in metric
units [with U.S. customary units in brackets].
Figures are not drawn to scale.

2. DESCRIPTION
The enclosure consists of a chassis with a lid, 12 blank
adapter plates (with attaching hardware), 2 front
mounting brackets, 2 (right and left) rear mounting
brackets, and mounting hardware. The mounting
holes in the enclosure chassis provide a choice of two
positions when mounting the enclosure onto the rack
or cabinet. See Figure 1.
The chassis features 12 channels for routing cable
and a rear brush. The rear brush is used to conceal
the inside of the chassis. Each channel is marked on
the front and back of the chassis to identify the
adapter plate it supports.
The enclosure accepts OM3 Hydra Kits 2193057-[ ],
SM Hydra Kits 2193758-[ ], and Cable Management
Adapter Plate Assembly 2111481-1. MPO adapter
plates are included with the hydra kits.
3. SAFETY PRECAUTIONS
DANGER
STOP
To avoid personal injury, ALWAYS wear eye
protection when working with optical fibers.
NEVER look into the end of terminated or
unterminated optical fibers. Laser radiation is
invisible, but can still damage eye tissue.
DANGER
STOP
To avoid personal injury, NEVER use defective or
damaged product. Punctured or stray laser
radiation may degrade system performance.
ALWAYS replace defective or damaged product
immediately.
— DO NOT remove the dust cap plug from a port
when the port is not in use.

— INSPECT BEFORE YOU CONNECT!
Before inspecting a fiber endface, DISCONNECT the
optical fiber from the power signal source. Always
clean and inspect a fiber endface before installing and
connecting the cable assembly.
— NEVER inspect the fiber endface when power is
applied to the optical fiber.

4.2. Preparation
Before beginning installation:
Rails of Rack (Ref)
Long Cutout of Bracket
Facing Up
— The enclosure must be installed directly below
the switch (no gap).
—If desired, remove the rear brush from the
chassis; the rear brush cannot be removed after
the enclosure is mounted onto the rack or cabinet.
4.3. Mount the Enclosure
1. Determine the vertical and horizontal (flush or
protruding) mounting position of the enclosure in the
rack or cabinet.
2. Using 4 of the 12-24 UNC-2A screws, install the 2
rear brackets onto the rack or cabinet (2 screws per
bracket, 1 bracket per side of rack or cabinet).
Observe the arrow and “TOP” marking on each
bracket (shown in Figure 1) for correct orientation
for installation (the long cutout of the bracket should
be facing up). See Figure 2. DO NOT tighten the
screws at this time.

3. Using the 6-32 UNC-2A screws, install the 2 front
brackets onto the chassis (8 screws per bracket, 1
bracket per side of chassis). Make sure that the
short leg of each bracket is facing forward. Tighten
the screws. See Figure 3.
4. Align the back of the chassis with the back of the
legs of the rear brackets. Slide the chassis through
the rails of the rack or cabinet and onto the legs.
Make sure that the legs enter the guide channels on
each side of the inside of the chassis. See Figure 4.
5. Insert 4 of the 12-24 UNC-2A screws through the
holes in the front brackets (2 screws per bracket),
and secure the front brackets to the rack or cabinet.
See Figure 5, Detail A.
6. Tighten the screws of the rear brackets to secure
the rear brackets to the rack or cabinet. See Figure
5, Detail B.

(Ref)
1. Label the end of each truck cable assembly.
2. Insert each truck cable assembly into the back of
the chassis so that it enters the applicable channel,
then slide the truck cable assembly through the
channel until the MPO connector exits the front of
the chassis. Allow a small amount of slack in the
truck cable assembly at the back of the chassis.
See Figure 6.
Figure 6
3. If desired, loosely wrap Hook and Loop Cable Tie
1375253-2, or similar cable tie, around the trunk
cable assemblies to provide strain relief at the back
of the rack or cabinet. Refer to Figure 6.
4. Connect the MPO connectors of each trunk cable
assembly to the back of an adapter of an MPO
adapter plate. Make sure to observe the port
designations marked on the front of the MPO
adapter plates. See Figure 7.
4.5.Install Adapter Plate(s)
Understand and follow the safety precautions given in
Section 3, then proceed with the following.
1. Using the captive screw attached to the MPO
adapter plate, install an MPO adapter plate onto the
front of the chassis for each opening to be used.
DO NOT remove the dust cap plugs. See Figure 7.
2. Using the captive screw attached to the blank
adapter plate, install a blank adapter plate or cable
management adapter plate assembly (includes 2
cable management saddles) onto the front of the
chassis for each opening without an MPO adapter
plate.
4.6.Connect HydraCable Assemblies
Understand and follow the safety precautions given in
Section 3, then proceed with the following.
1. Install Parking Cap 1553641-1 to any empty switch
blades that do not have a transceiver to support the
LC connector leg of the hydra cable assembly
.
2. Connect the LC connectors of the hydra cable
assemblies to the applicable ports of the switch
blade (each LC connector is labeled to match the
port markings). See Figure 8.

3. Remove the dust cap plugs from the ports of the
MPO adapter plates to be used. DO NOT remove
the dust cap plugs from the ports not to be used.
4. Connect the MPO connectors of the hydra cable
assemblies to the applicable port of the MPO
adapter plate. See Figure 8. The port designations
and color codes are marked on the front of the MPO
adapter plate, and the MPO adapters are keyed to
match the MPO connectors of the hydra cable
assemblies.
