H3C VG 21-08 Voice Gateway (hereinafter referred to as VG

21-08) is a new-generation access device intended for enterprise and

SOHO (Small Office, Home Office) users. It integrates the access of

voice, fax, and data signals over IP networks, functioning to transform

analog voice or fax signals to IP data and forward the data.

The VG 21-08 provides abundant IP telephony features, such as

Voice over IP (VoIP), Fax over IP (FoIP), call control, resources

management, and maintenance management, as well as multiple

coding schemes. It also supports DHCP Client, boasting excellent

price/performance ratio.

The VG 21-08 provides eight FXO ports and two Ethernet

interfaces. So it can connect to the subscriber line of a

program-controlled telephone switching system through the FXO

ports and connect to the Internet through the Ethernet interfaces.

Installation Preparations

Chapter 2 Installation Preparations

2.1 Site Requirements

The VG 21-08 is intended for indoor use. To ensure normal

operation and long service life for your device, install it in an

environment that meets the requirements described in the following

subsections.

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 21-08.

The following table lists temperature and humidity requirements

for the VG 21-08.

Table 2-1 Temperature/Humidity requirements in the equipment

room

Temperature Relative humidity

0°C to 40°C (32°F to 104°F)

2.1.2 Cleanliness

The equipment room must be free of explosive, electric, magnetic,

and corrosive dust. The contents of dust must be limited as shown in

the following table:

Table 2-2 Requirement on dust content in the equipment room

Max. particle size (μm)

0.5 1 3 5

Max. concentration

(number of particles per

cubic meter)

1.4 × 10

7 × 10

2.4 ×

1.3 ×

Besides dust, there are rigorous limits 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 21-08 is designed to be Electrostatic Discharge

(ESD) preventive, excessive static electricity may enormously

damage the card circuits or even the whole device.

Static electricity affecting the VG 21-08 and the related network

mainly comes from outdoor high-pressure power cables and electric

fields caused by thunder and lightning as well as indoor environment

and materials. To prevent 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 temperature and 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 sales representative maintains your

VG 21-08. Huawei-3Com is not liable for any damage or consequence

resulted from users' operation without permission.

2.1.4 Electromagnetic Environment

Any possible interference source, wherever it is from, impacts the

VG 21-08 negatively in the form of capacitive coupling, inductive

coupling, electromagnetic radiation, or common-impedance (including

the grounding system) coupling. To resist the interference, make sure

to:

z Take effective measures against the interference caused by

the electrical power grid.

z Use a grounding system or lightning protection grounding

different from that for the power supply system and keep

them as far as possible.

z Keep the device far from radio transmitting station, radar

station, and high-frequency high-current devices.

z Use electromagnetic shielding when necessary.

2.1.5 Lightning Protection

Although the VG 21-08 is designed to be lightning resistant,

excessive lightning interference can damage your device. To protect

your device against lightning.

z Ensure the chassis is connected to earth ground.

z Ensure the earth point of the power socket is well connected

to earth ground.

z Add a lightning arrester to the front end of the power input to

better protect the power supply against lightning strikes.

2.1.6 Checking the Rack

When installing the VG 21-08 in a rack, make sure that:
