This document aims to provide simple and distinctive guidelines for hardware installation.
This document does not describe operations for the pre-delivery installation. Instead, this document
describes only the operations for on-site installation.
NOTE
Electrostatic Discharge
Before touching the device, or holding the boards and IC
chips, wear the anti-static wrist strap to prevent the
electrostatic discharge of the human body from
damaging the sensitive components. Ensure that the
other end of the antistatic wrist strap is well grounded.
Bundling Cables
The distance between cable ties or fiber binding straps inside the cabinet should be within 250 mm. (For
subscriber cable, the distance is 200mm. )
The distance between cable ties for all cables and corrugated pipes outside the cabinet is determined
according to the distance between two horizontal beams. For the cabling trough without beams, bundle the
cables with the distance not exceeding 250 mm between cable ties.
Pre-Installation Check
Verify that the equipment room, power supply, ground cables and optical cables are ready for installation.
Start the installation according to the engineering design documents after confirming that conditions are met.
Refer to the Installation Guide for information about specific operational requirements and technical
specifications.
Affixing Labels or Tags
Affix the label or tag to the signal cable, 2 cm away from the connector. When the cable is placed vertically,
the label or tag should point towards the right. When the cable is placed horizontally, the label or tag should
point downwards.
Precautions

Instructions and Precautions for Handling Boards
Do not hold a board without hand protection. Wear an ESD wrist strip or ESD gloves before handling a board.
Insert filler panels into vacant slots on an NE to prevent foreign matters from getting into the NE, which may
result in faults on the NE.
Boards are fragile and valuable. When handling or placing a board, exercise caution and put it into a
dedicated packing box.
Holding aboard without hand protectionWearing ESD gloves Wearing an ESD strip
Hold the front panel of a board with hands.

A DC PDC contains eight power inputs and eight power outputs. If a short-circuit copper bar is used, the eight
power inputs and eight power outputs are changed to four power inputs and eight power outputs.
Area A and area B of the DC PDU serve as mutual hot backups.
The power output terminal at side A of the DC PDU provides two channels of power supplies to the PIU
housed in slot 27 of the OptiX PTN 3900 subrack. The power output terminal at side B of the DC PDU
provides two channels of power supplies to the PIU housed in slot 28 of the subrack.

Installing and Routing Power Cables －Installing Copper Plates on Site (TN81PDU)
Do not install the copper plates in the power supply output area of the DC PDU. You should determine
whether the copper plates are installed in the power supply input area only according to the on-site power
supply situation.
If new equipment is not configured with sufficient external power inputs according to the standard
configurationsof a cabinet, instead, if it is configured with external power inputs according to the number of
actually configured subracks, power cables of the subracks need to be increased during later installation of
subracks for expansion. For how increase the power cables, refer to the Appendix.
The following figures show how to install short-circuit copper bars in Area A. The method to install short-circuit
copper bars in Area B is the same as that in Area A.
Determine the input terminal groups to be short-circuited. Install the copper plate on the input terminal
groups (+) to be short-circuited. Then, connect the external power cables (black) to the input terminals (+).
Repeat the preceding operations and short-circuit the target input terminal groups (-). Then, connect the
external power cable (blue) to the input terminals (-).
Repeat the preceding operations and short-circuit the target input terminal groups (-). Then, connect the
external power cable (blue) to the input terminals (-).

Do not install the copper plates in the power supply output area of the DC PDU. You should determine
whether the copper plates are installed in the power supply input area only according to the on-site power
supply situation.
Determine the input terminal pairs that must be connected internally. Then position the copper plates to the
NEG(-) input terminals on the air breakers on the PDU. Tighten the screws on the air breakers to secure
the copper plates. Note that there are copper plates targeted for the left and right power input areas and
they are not interchangeable.
Install an appropriate copper fitting on the RTN(+) input terminals in the middle of the PDU.
Connect external power cables (blue) to the NEG(-) input terminals and BGND cables (black) to RTN(+)
input terminals.

Do not install or demount the power cable while the power is on. To avoid personal injuries, turn off the power
before performing the operations.
The signal cable, power cable and fiber should be routed and bundled separately. Connect these cables in
sequence: PGND cable > BGND power cables > -48 V power cables.
When installing the PGND cable, connect the PGND cable to one grounding bolt on the cabinet and to the
grounding bar on the other side.

When the power cables are routed downward, the number of cables respectively routed on the two sides of
the cabinet should be the same. See the previous figure.
