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.
