Installation Flow
Reference information
Operation
When the delivered subrack has been equipped with boards in cabinet, you can skip the steps involving "Installing
Subrack" and "Installing Boards and Components".
NOTE
If boards have been installed on a PTN 7900-32 before delivery, do not remove any board or module (such as the fan
module) during transportation. To learn how to replace boards and modules after an installation is complete, see the
chapters "Installing the Subrack" and "Installing Boards and Components ".

CAUTION
ESD Protection
Always wear ESD gloves or an ESD wrist strap prior to contact with the equipment or before handling devices, boards,
or IC chips to prevent damage to sensitive components due to electrostatic discharge from the human body. Ensure that
the ESD wrist strap is properly grounded.
CAUTION
Pre-Installation Check
Ensure that the equipment room, cabinets, power supplies, ground cables, optical cables, and associated devices are
ready for installation. Start the installation according to the engineering design documents after confirming that all
conditions are met.
Bundling Cables
Binding intervals between cable ties or optical fiber binding straps inside the cabinet cannot exceed 250 mm. (Binding
intervals cannot exceed 200 mm for user cables.)
Binding intervals between cable ties for all cables and corrugated pipes outside the cabinet are determined based on
the distance between the two horizontal beams. If the cable trough does not contain any beams, the binding intervals
between cable ties cannot exceed 250 mm.
CAUTION
Safety Information
Always wear protective gloves when lifting or transporting a cabinet to prevent hand injuries or damage to the cabinet
surface.
The equipment is heavy. To prevent human injuries or equipment damage, always use a lifting device to transport or
position the equipment. Use a pallet truck or heavy-duty bogie wagon to transport the equipment on even ground, and
use a cargo lift to transport the equipment between different floors.
CAUTION
This document provides guidelines for quick hardware installation. It describes procedures for onsite installation,
but does not describe pre-delivery assembly.
NOTE
Installation Precautions

Requirements and Precautions for Operating Boards
22
Always wear ESD gloves to operating a board to prevent damage to sensitive components.
Any vacant slot must be covered by a filler panel to
prevent foreign objects from entering the subrack or
system ventilation ducts. Foreign objects may
cause an NE failure.
Boards are fragile and vulnerable. When transporting or placing a board, exercise caution and ensure that
the board is packed in a dedicated box to protect the board against damage.
Boards must be packed with original packaging materials during transportation. If the original packaging
materials are lost, contact Huawei technical support personnel.
Hold the protection plate under the board with hands and handle with care.

panels into upper-portion slots, ensure that the ejector levers are on
the left side of the front panels. When installing service boards or filler
panels into lower-portion slots, ensure that the ejector levers are on the
right side of the front panels.
Wear an ESD wrist strap or ESD
gloves during operations.

2 Installing Fan powered box
Determine the mounting direction of the
Fan powered box and push it into the slot.
Press the button on each side of the Fan powered box and push
the assembly until it is fully seated in the slot. After releasing the
buttons, check whether they are restored to their original positions.
If they are not, withdraw the Fan powered box, restore the buttons
to their original positions, and then install the Fan powered box
again.
NOTE
A yellow-green button is located on the
left and right sides of a Fan powered
box. You must press these two buttons
to completely plug the Fan powered box
into the subrack or to remove it from the
slot.
Button
The air flows in the upper and lower portions of a cabinet are in opposite directions, so the Fan powered box assemblies at
the top and bottom of the cabinet are installed differently. Four labels are located on the Fan powered box: two on the top
surface and two on the bottom. One of the labels, a mounting direction label, indicates the mounting direction of the Fan
powered box. Another mounting direction label is present on the air blocking panel that covers a vacant Fan powered box
slot or inside the Fan powered box slot. When installing a Fan powered box in the upper portion of a cabinet, ensure that the
mounting direction label on the right of the Fan powered box surface faces upward. When installing a Fan powered box in
the lower portion of a cabinet, ensure that the mounting direction label on the left of the Fan powered box surface faces
upward.
The Fan powered box is designed for
easy installation. If you feel a blockage
when inserting a Fan powered box into a
slot, remove it and check whether it was
inserted correctly. Do not use force to
insert the Fan powered box.

Do not install or remove power cables while the equipment is powered on. Ensure that the circuit breaker or fuse
of the first power cabinet is disconnected prior to removing or installing a power cable to avoid bodily injuries.
CAUTION
•The equipment is powered off only after all power inputs to each PIU
board are disconnected.
WARNING
•The label below advises you to read corresponding manuals before
operating the equipment.
•Install the OT terminals on the power cables according to the instructions
on the plastic cover of each PIU board. Ensure that the terminals are

When the number of power inputs for the array cabinets in the equipment
room of the customer cannot meet the requirements of the 5 + 5 power
supply solution, short-circuiting processing is required for power input of
the PIUs using copper fittings. There are two locations for installing copper
fittings on a PIU. Install short copper fittings and corresponding input
power cables, and then install long copper fittings and corresponding input
power cables.
