Precautions
This document provides quick guidelines for hardware installation.
This document does not describe pre-delivery assembly. This document pertains to onsite installation.
Electrostatic Discharge
Put on ESD gloves or an ESD wrist strap before handling plugboards, 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
The binding intervals between cable ties or fiber binding straps inside a cabinet must not exceed 250 mm.
The interval must not exceed 200 mm for user cables inside a cabinet.
If a cable trough passes two through beams, binding intervals between cable ties for all cables and
corrugated pipes outside a cabinet are determined by the distance between the two beams. If a cable trough
does not pass through beams, the binding interval between cable ties must not exceed 250 mm.
Pre-installation Check
Check that the equipment room, cabinet, power supply, ground cables, optical cables, and associated
facilities are all ready prior to installation.
Installation Environment
The device does not have an air filter. It is recommended that the air filter be dustproof at the cabinet level.
This device is a class A product, which can only be installed indoors.
A product and may cause radio interference in a living environment. In this case, you may need to take
feasible measures for the radio interference.
Devices such as wireless antennas cannot be installed in the equipment room. If the devices must be
installed, they must be lower than the electromagnetic environment requirements (for details, see the
electromagnetic environment requirements) or add necessary electromagnetic shielding measures.
