Precautions

NOTE

This document provides quick guidelines for hardware installation.

This document does not describe pre-delivery assembly. This document describes only procedures for

onsite installation.

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

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.

CAUTION

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.

CAUTION

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.
