Mounting the Zero RU to the front of the equipment rack:
FS129A
The HD Flex Zero RU can be mounted onto a previously
installed equipment rack using existing screws and the
HD Flex Rail Adapter Plate. The HD Flex Zero RU can be
mounted on either the left or the right rail of the
equipment rack.
1. Remove screws from existing equipment that align with
mounting holes in the HD Flex Zero RU Rail Adapter
Plate.
2. Loosen screws from existing equipment that align with
the slits in the HD Flex Zero RU Rail Adapter Plate.
3. Slide the HD Flex Zero RU Rail Adapter Plate under
the loose screws.
4. Replace and tighten the removed screws.
5. Attach the HD Flex Zero Cassette Holder assembly
to the HD Flex Zero Rail Adapter Plate using four
(4) #10-32 hex nuts

Mounting the HD Flex Zero RU to the back of the equipment rack:
If the space in front of the equipment rack is
inadequate, the HD Flex Zero RU can be mounted to
the back surface of the equipment rack.
1. Attach the HD Flex Zero RU Rail Adapter Plate to
the back surface of the equipment rack using four
(4) screws.
2. Attach the HD Flex Zero RU Cassette Holder
assembly to the HD Flex Zero RU Rail Adapter Plate
using four (4) #10-32 hex nuts.

Cassette Assembly (sold separately):
Polarity Label
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. To
install cassettes, insert into slot and push forward until
it snaps into place.

Cassettes can be removed from the front, as needed,
for replacement or migration. Disconnect patch cords
from the front of the cassette. Press the latch away
from the cassette and pull the cassette forward. Once
the cassette is pulled past the latch, the cassette can
be completely removed.
Disconnect the trunk cable from the rear of the
cassette and connect to the rear of the replacement
cassette.
Re-install the cassette or MPO FAP opposite the way it
was removed. Align the rear of the cassette or MPO
FAP in the opening and push inward until the cassette
snaps into place (for cassette changes).
FS129A
Cassettes can be removed from the back, as needed,
for replacement or migration. Disconnect patch cords
from the front of the cassette. Press the two latches on
the back of the cassette inward, then with the latches
squeezed together, pull the cassette out through the
back.

1. Insert diagonally until
rear of boot is just
past the rear post.
2. Lift cable over post.
Installing Additional Cassette Holders:
Figure 12
FS129A
If migrating to an MPO FAP, connect the MPO trunk
cable to the left most position, port 1.
To install additional trunks, remove the MPO FAP
through the back of the HD Flex Zero RU and attach the
trunks as needed.
If the MPO FAP cannot be removed through the back,
due to lack of slack in the front cables, insert the MPO
connector into the rear of the FAP diagonally between
the posts. Push the 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. Pull the FAP with
the "held" MPO trunk out through the front of the HD
Flex Zero RU. Remove the dust cap and connect the
MPO to the appropriate port of the FAP.
FAP can accommodate "holding" up to 3 MPO
connectors at a time.
The cassette holders are designed to latch to one
another and can be added or removed as needed. For
most applications, a maximum of four (4) cassette
holders can be latched together.
To remove the label card holder, depress the two locking
latches of the cassette holder below it.
Keeping the locking levers depressed, slide the label
card holder back out of the four (4) engagement hooks
of the cassette holder below it.

Reconfiguring the port configuration on the Zero RU Cassette Holder:
Select the rail to be removed. Grip the end of the rail and pull it
away from the cassette holder.
While continuing to apply pressure on the rail being removed,
pull the rail forward. As the rail begins to move, it will disengage
from the tray and be free to remove completely.
FS129A
To install the rail into the cassette holder, align the rail between
triangular cutouts and reverse the removal process. The posts
on the bottom of the rail will drop into the cutouts of the cassette
holder. As the rail is pushed toward the back of the cassette
holder, the posts will engage the cassette holder. Once the rail
is fully re-inserted, the front of the rail will snap into position.
Pull forward on the rail to ensure it is properly installed.

Labeling options for the HD Flex Zero RU 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 layout is
shown in Figure 24. Panduit label part #C061X030FJJ
can be used for single port identification, Panduit label
part #C125X030FJJ can be used for 2-port
identification, Panduit label part #C252X030FJJ can
be used for 4-port identification, or Panduit label part
#C379X030FJJ can be used for 6-port identification.

The label card coincides with the port labeling as
shown in Figure 25. Cassette holder 1 is the closest
to the mounting surface (the layout shows ports 1 12 on the first cassette holder, ports 13 -24 on the
second cassette holder, etc).
The label card should be stored in the label card
holder.
