Dimensions in this instruction sheet are in
millimeters [with inches in brackets]. Figures are
not drawn to scale.
2. DESCRIPTION
The enclosure consists of a chassis, slide–out tray, a
3–position faceplate for unshielded twisted pair (UTP)
fiber/optical fiber applications, and a 4–position
faceplate for UTP fiber applications. Three “snap–in”
adapter plates are included with the 3–position
faceplate.
At the back of the tray is a cutout for cable exit and
four tie–down brackets used for securing the fiber to
the tray. The tray is held closed by two flip latches.
Two universal mounting brackets and four 12–24
UNF–2A pan head screws are included for mounting
in the rack.

housing until the lower lip ‘snaps’ into place.
d. If necessary, to remove the housing from the
faceplate, refer to Paragraph 4.4.
4. Terminate the pc board assembly according to
the instructions included with the pc board
assembly.
Then install the pc board assembly
according to the following.
The pc board assembly must be terminated
before installation. The faceplate is not designed
to support the pc board assembly during
termination. Terminating the pc board assembly
installed in the faceplate could result in personal
injury or damage to the pc board assembly.
a. Position the pc board assembly over the back
of the housing. Orient the pc board assembly so
that the connector ports (side of pc board

b. Firmly push the pc board assembly into the
housing in an
even manner, making sure that all
four locking tabs engage the pc board assembly.
There will be an audible “click” when the pc
board assembly is fully seated.
c. If necessary, to remove the pc board
assembly from the housing, refer to Paragraph
4.3.
5. Install an adapter block according to the
following.
a. Position the adapter block over the back of
the housing. Orient the adapter block so that the
connector ports face the housing and the keyed
slots in the adapter block align with the keyed
tabs on the housing. See Figure 6, Detail B.
b. Firmly push the adapter block into the
housing in an
even manner, making sure that all
four locking tabs engage the adapter block.
There will be an audible “click” when the adapter
block is fully seated.
c. Install connectors according to the
instructions packaged with the connectors.

3.4. Term nate and Route the F ber
ALWAYS wear eye protectio whe worki g with
optical fibers. NEVER look i to the e d of a
termi ated or u termi ated fiber. Laser radiatio
is i visible but ca damage eye tissue. NEVER
eat, dri k, or smoke whe worki g with fibers.
This could lead to i gestio of fiber particles.
IMPORTANT: Follow approved local grounding
procedures, and conform to local requirements.
Use the following guidelines when 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:
S Allow enough fiber in the enclosure for routing
S Keep bend radii of fiber as large as possible
(always follow manufacturer’s minimum bend
radius)
DO NOT exceed mi imum be d radii for the
fiber. ALWAYS avoid placi g fiber u der te sio
or torsio .
Proceed as follows:
1. For fiber applications, terminate the fibers onto
connectors according to the instructions included
with the connectors.
BE VERY CAREFUL to dispose of fiber e ds
properly. The fibers create slivers that ca easily
pu cture the ski a d cause irritatio .
2. Route the fiber through the cutout in the back of
the tray. Make sure that at least 305 [12.0] of fiber
is inside the enclosure.
3. Remove the dust covers from the connectors.
Retain the dust covers. Join the connections to the
appropriate connections.
4. Coil excess fiber onto the tray, and secure the
fiber to the tie–down brackets using cable ties. See
Figure 7.
3.5. Inspect and Close the Enclosure
1. Record connector positions using the
identification card.
2. Inspect installation according to the following:
— enclosure is secure to rack (pan head screws
are tight)
— fiber is not nicked or broken
— excess fiber is coiled and secured to
tie–down brackets

3. Slide the tray into the chassis, and close the
latches. See Figure 8. Inspect closing according to
the following:
— latches are fully closed and secured to
chassis
— no fibers are pinched between the chassis
and the tray
4. RE-INSTALLING AND DISASSEMBLING
4.1. Installing Adapter Plate onto Faceplate
1. Position the adapter plate over the front of the
faceplate so that the split end of the lock pins align
with the holes in the faceplate.
2. Push the lock pins into the holes until the
adapter plate is secure (there will be an audible
“click”).
4.2. Removing Cassette from Faceplate
Pull the lock pins of the cassette until the cassette
releases from the faceplate.
4.3. Removing PC Board Assembly or Adapter Block
from Interface Housing
1. If the interface housing is installed onto the
faceplate (with the pc board assembly or adapter
block installed), remove the housing from the
faceplate (refer to Paragraph 4.4).

2. The pc board assembly and adapter block are
each held in the housing by four locking tabs.
Insert the tip of a small flat–blade screwdriver
between the pc board assembly or adapter block at
the locking tab slot. Slightly lift the blade to release
the locking tab.
3. Release each locking tab in the same manner,
then pull the pc board assembly or adapter block
from the housing.
4.4. Removing Interface Housing from Faceplate
From the front of the faceplate, firmly push the lower
lip of the housing through the faceplate. Slightly tilt
the housing and apply a slight downward pressure to
the upper lip until the housing is released from the
faceplate.
