If desired, mounting brackets can be adjusted to change
the position of the front of the enclosure relative to the
equipment rails. Brackets are adjustable in 0.50"
increments.
If RU space is open above enclosure location, partially
install two screws, one on each side of the rack. These
partially installed screws will assist in mounting the
enclosure to the rack.

latches down and swing door open.
Install the remaining screws and tighten all to secure the

The enclosure trunk slack plate (sold separately as
Panduit part no. FLEX-PLATE1U, FLEX-PLATE2U, and
FLEX-PLATE4U) installs to the rear of the enclosure.
Engage the pins on the plate into the slots on the
enclosure and tilt down into place. Tighten captive screws
to secure.
The trunk slack plate includes an optional vertical divider
to aid in organizing and managing the cables. Divider
plates are recommended for split routing. Do not use the
divider if routing all rear cables to one side of the rack.

The enclosure rear cover kits (FLEX-PLATE*UR*) will include 3
pieces:
1. Enclosure trunk slack plate compatible with rear covers
The enclosure trunk plate compatible with rear covers (See figure
6) is the same length as the trunk slack management plate sold in
FLEX-PLATE*U. Features which differentiate it from the trunk
slack management plate in FLEX-PLATE*U are as follows:
•Holes located on flanges to accept plungers and grommets
used to fasten rear covers to trunk slack plate
•Slot added to trunk plate to be used as an extra Tak-Ty slot
for holding down cable exiting the enclosure
The rear cover will sit on the back waterfall feature of the trunk
management plate when properly installed. Instead of using a tie
down point with the Tak-Ty wrapped around the back waterfall of
the trunk slack pate, use the extra slot to create a tie down point
and properly route the cables off the slack management plate.
2. Rear cover (1RU, 2RU, and 4RU options for FLEX-PLATE1UR*, FLEX-PLATE2UR* AND FLEX-PLATE4UR*)
The 2RU and 4RU rear cover options will have brushes installed to protect the opening where cable exits the rear cover.

The enclosure plate compatible with rear covers can be installed in the same fashion as the enclosure trunk slack plate explained previously.
Engage the pins on the plate into the slots on the enclosure and tilt into place. Tighten captive screws to secure.
The 2RU and 4RU rear cover options will have brushes installed to protect the opening where cable exits the rear cover.

To install the respective rear cover, slide the rear cover over the installed slack plate. Fasten the rear cover to the slack plate by depressing the
plungers after they have been inserted into the holes on the slack plate compatible with the rear cover. The middle tongue on the rear cover
must be situated underneath the center flange bracket on each enclosure to ensure collect installation

Note: Prior to cassette installation, make sure door on front of
enclosure is closed.
First, attach trunk cabling to the rear port of the cassette or FAP to be
installed. Note the polarity label on the cassette and orient properly as
needed. Cassettes should be installed one at a time starting with the
bottom most slot on the right, as shown. To install cassettes, insert
into slot and push forward until it clicks into place.
Populate the entire row across from right to left before moving to the
next row above. Repeat process until all desired slots are filled.
Create a slack loop for all incoming trunk cable. Slack
is required to allow movement of the trays from the
front of the enclosure. For split routing, allow a
minimum of 28" of slack from the rear of the cassette
to the tie down point. When routing cables all to one
side, allow a minimum of 32" of slack from the far side
of the enclosure to the tie down point. Use Tak-Tys to
secure trunk cables to the cable slack plate or vertical
cable manager as needed. Test trays to make sure
they move freely after routing cable and adjust if
necessary.

FAPs that can be installed

Patch cable is installed from the front of the enclosure.
Open enclosure door to expose cassettes. Pull bottom
tray out slowly until it clicks into the first stop position,
the service position.
Cassettes are compatible with LC Uniboot patch
cords.
Panduit recommends split routing for patch cable. For
split routing, the unification clip must be removed to
allow each side of the tray to move independently.
To remove the clip, lift up on the front of the clip, rotate
upward 90°, and lift out. Discard or set aside for future
use as needed. To re-install clip, reverse the
procedure.
FS127A
Split Routing (Recommended)
Unified Routing
Install patch cords into the front of the cassettes
working from left to right starting with the bottom most
row. Populate each row across before moving to the
next row above. Repeat process until all patch cabling
is installed.
For unified routing (all cables routed to one side) leave
unification clips installed.

Cassettes can be removed from the front of the
enclosure as needed for replacement or migration.
Open door and slide tray out slowly until it clicks into
the second stop position, the cassette change
position.
Disconnect patch cords from the front of the cassette.
Lift cassette up from the front to disengage it from the
tray and remove.
Figure 21
Disconnect trunk cable from the rear of the cassette
and connect it to the rear of the replacement cassette.
Re-install cassette or MPO FAP opposite the way it
was removed. Align the rear of the cassette or MPO
FAP in the tray first, push inward until the cassette
stops, then press down gently on the top of the
cassette, near the front/center, until it clicks into place.
Re-attach patch cords (for cassette changes) and
push tray back into the enclosure to the home position.
Note: Tray resistance is intended to support cassette
during patch cord installation. This resistance must be
overcome to return tray to the home position.
If migrating to an MPO FAP, connect the MPO trunk
cable to left most position, port 1.

Installing Additional MPO Trunks
INSTALLATION INSTRUCTIONS
From the rear of the enclosure, select the FAP to add
additional MPO trunk cables to. Insert the MPO
connector into the rear of the FAP diagonally between
the posts. Push connector in until the rear of the boot
just passes the rear post and lift the cable over the
post to “hold” the connector in place.
Move to the front of the enclosure and pull open the
tray containing the FAP with the “held” MPO trunk
cable to the cassette change position (as shown in
Figure 21). Remove the dust cap and connect the
MPO to the appropriate port on the FAP. Return tray
to the home position.
FAP can accommodate “holding” up to 3 MPO
connectors at a time. Follow the steps in Figure 30.
Once all connectors are held in place, move to the
front of the enclosure and pull open the tray containing
the FAP to the cassette change position (as shown in
Figure 21). Remove dust caps and attach the MPO
connectors to the appropriate ports (Step 6 in Figure
30). Return tray to the home position.

Labeling
Labeling options for the HD Flex Fiber Enclosures allow for identification to follow the EIA 606-B labeling standards. Panduit labels, used in
conjunction with Panduit Easy-Mark Labeling Software, simplifies label creation and allows for ease of editing and label replacement when
necessary. The labeling location in the upper right corner of the enclosure door, as shown in Figure 31, is used for identifying the enclosure
within the cabinet or rack. Panduit label part #C125X030FJJ fits in this area.
Panduit Part #C125X030FJJ
Figure 31
The labeling layout for the 1U enclosure is shown in Figure 32 below for typical application. Panduit label part# C061X030FJJ can be
used for single port identification, Panduit label part # C125X030FJJ for 2-port application, Panduit label part # C252X030FJJ for 4-port
application, and Panduit label part # C379X030FJJ for 6-port identification.

The label on the inside of the front cover coincides with the port and tray labeling as shown below in Figures 33 & 34. Trays 1 and 2 are
the lowermost trays (the layout shows ports 1 - 24 on the first two trays).
