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 pipes outside the cabinet are
determined according to 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.
Pre-installation Check
Check the telecommunications room, cabinet, power supply, ground wires, optical cables, and
associated facilities prior to installation. Start the installation according to the engineering design
documents after verifying that conditions are met.
NOTE
CAUTION
CAUTION
CAUTION
Power Supply
The equipment uses a -48 V/-60 V DC power supply. An AC power supply or a high-voltage power
supply may cause equipment damage or even human injuries and therefore is forbidden.
CAUTION

3
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 a board without hand protectionWearing ESD gloves Wearing an ESD strip
Hold the front panel of a board with hands.
