Installation Preparations

Chapter 2 Installation Preparations
2.1 Site Requirements
The VG 31-08 is intended for indoor use only. To ensure normal
operation and longevity of your device, install it in an environment that
meets the requirements below.
2.1.1 Temperature/Humidity
You must keep the temperature and humidity in the equipment
room within a certain range. Long-term high humidity will lead to bad
insulation or even electricity leakage, mechanical property change,
and corrosion. However, too low relative humidity is likely to leave
captive screws loose due to contraction of insulation washers and
static electricity that threatens the CMOS circuit on the device. High
temperature accelerates aging of insulation materials and lowers
reliability and service life of your VG 31-08.
The following table lists temperature and humidity requirements
for the VG 31-08.
Table 2-1 Temperature/Humidity requirements in the equipment
room

2.1.2 Cleanliness
The equipment room must be free of explosive, electric, magnetic,
or corrosive dust. The contents of dust must be limited as sh own in the
following table:
Table 2-2 Requirement on dust content in the equipment room
Max. particle size
(μm)

Besides dust, there are rigorous limit s on harmful gases that can
accelerate erosion and aging of metals, such as salts, acids, and
sulfides, as shown in the following table.

2.1.3 ESD Prevention
Although VG 31-08 is designed to be electrostatic discharge
(ESD) preventive, it may be damaged by excessive static electricity.
Static electricity affecting the VG 31-08 and the related network
mainly comes from outdoor electric fields caused by high-pressure
power cables or thunder and lightning, as well as indoor environment,
materials and device structure. To prevent ESD damage, observe the
following:
z Ensure the unit and the floor is connected to earth ground.
z Keep the equipment room clean.
z Maintain suitable temperatu re an d humidity.
z Wear an ESD-preventive wrist strap and uniform when
handling the circuit board.
z Place the removed circuit board on an ESD-preventive
workbench or in an antistatic bag right-side up.
z Hold the removed circuit board only by its edge when
observing or moving it. Do not touch the components on it.
Warning:
There is an anti-dismantle seal on a screw on the chassis. You must
keep the seal intact before your agent maintains your VG 31-08.
Huawei-3Com is not liable for any damage or consequence resulted
from users' operation without permission.
