Precautions
This document provides quick guidelines for hardware installation.
This document does not describe pre-delivery assembly. This document describes only procedures for
onsite installation.
Electrostatic Discharge
Wear ESD gloves or an ESD wrist strap prior to contact
with the equipment or before handling the plug-boards,
boards, and IC chips to prevent damage to sensitive
components caused by electrostatic discharge from the
human body. Ensure that the other end of the ESD
wrist strap is properly grounded.
Binding Cables
Binding intervals between cable ties or optical fiber binding straps inside the cabinet cannot exceed 250 mm.
(The distance cannot exceed 200 mm for user cables).
Binding intervals between cable ties for all cables and corrugated tubes outside the cabinet are determined
accordingto 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.
Checking Before Installation
Check the telecommunications room, cabinet, power supply, ground cables, optical cables, and
associatedfacilities prior to installation. Start the installation according to the engineering design
documents after confirming that conditions are met.

Regulation and Precautions for Board Handling
Do not hold a board without hand protection. Wearan 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 and system
air ducts from being damaged, which may resulting 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.
Coherent boards, such as TN12LSC, TN11LTX, TN15LSXL, and TN55NS3, must be packed with original
packagingmaterials during transportation. If the original packaging materials are lost, contact Huawei.
