OVERVIEW

Introduction H3C MSR 20 Series Routers were self-developed by Hangzhou H3C Technologies

Co., Ltd. for use on enterprise-level networks. Depending on the network size,

MSR 20 Series Routers can be either core routers on small and medium enterprise

networks, or access routers for network branches on some large-sized enterprise

networks. Therefore, MSR 20 Series Routers are suitable for the application on the

carrier-level networks, such as telecom management networks and billing

networks. MSR 20 Series Routers adopt modular design and provide a wide range

of optional smart interface cards (SICs). The MSR-20, MSR 20-21 and MSR 20-40

are available with AC-powered units.

Currently, the H3C MSR 20 series includes the following models:

■ MSR 20-20

■ MSR 20-21

■ MSR 20-40

Router Model and

Structure

The H3C MSR 20 Series Routers include MSR 20-20, MSR 20-21, and MSR 20-40.

These three models are similar in chassis structure and layout. All of them can be

put on the tabletop and can be mounted in 19-inch standard racks. The following

subsections will give you more details about these three models.

LED Description

16 CHAPTER 1: OVERVIEW

■ Currently, MSR 20 series routers do not support PoE and regard SIC-4FSW-POE

and DSIC-9FSW-POE (if used) as only ordinary Layer 2 switching modules.

ESM Module

■ High-performance network data encryption ESM module (ESM-ANDE)

■ Standard network data encryption ESM module (ESM-SNDE)

ESM module supports IPSec and by using hardware encryption expedites IP packet

encryption. The use of hardware encryption/decryption and hashing operation

allows the router to encrypt packets with high performance and reliability.

The encryption card is optional. On a router installed with an encryption card, the

main control board functions to route IP packets and implement

encryption-enabled VPN, while the encryption card functions to encrypt packets.

VPM and VCPM Module VPM (Voice Processing Module) functions to implement the encryption/decryption,

EC and CNG of voices.

VCPM (Voice Co-Processing Module) processes the voice data in combination with

VPM.

■ Voice co-processing module (RT-VCPM)

■ 8-channel voice processing module (RT-VPM8)

■ 16-channel voice processing module (RT-VPM16)

■ 24-channel voice processing module (RT-VPM24)

■ 32-channel voice processing module (RT-VPM32)

n

VPM/VCPM is only available on MSR 20-40.

INSTALLATION PREPARATIONS

Requirements on

Environment

H3C MSR 20 Series must be used indoors. To ensure the normal operation and

prolong their service life, the following requirements for installation site must be

met.

Requirements on

Temperature/Humidity

To ensure the normal operation and prolong their service life, certain requirements

on temperature and humidity in the equipment room shall be met. If the relative

humidity is too high, the insulation materials in it will deteriorate easily or even

lead to electric leakage. Sometimes this will result in change to the mechanical

performance of the materials and rusting of the metal components. If the relative

humidity is too low, the fastening screw will become loosen due to shrinkage of

the isolation spacer. In an environment with dry climate, static electricity may be

produced, putting the CMOS of the router to risk. High temperature is of the

greatest risk: for it will significantly degrade the router’s reliability, speed up aging

process of the insulating materials, and shorten the service life of the router.

The requirements on the temperature and humidity for MSR 20 Series are shown

in the following table:

Requirements on

Cleanness

Dust is harmful to the safe operation of the Router. Dust on the chassis may result

in static absorption, thus causing poor contact of the metal connection

components or points. Especially under the condition of low indoor humidity, dust

is easier to be absorbed.

The requirements on the dust concentration and diameter are shown in the

following table:

Besides the dust specifications, the equipment room of the Router should also

meet the rigorous requirements for the content of salt, acid and sulfide. These

harmful gases could accelerate the metal erosion and aging process of some parts.

The specific limits of these harmful gases as SO

are given

18 CHAPTER 2: INSTALLATION PREPARATIONS

Requirements on

Electrostatic Discharge

Prevention

Although many antistatic considerations have been given to H3C MSR 20 Series,

damage to the router’s circuit or even the whole equipment may still happen when

the static electricity exceeds the tolerance threshold.

In the communication network to which the routers are connected, static

induction mainly comes from two aspects: external electric fields such as outdoor

high voltage power line or thunder and internal environment like flooring

materials or the whole equipment structure. Thus, the following should be

considered to safeguard the equipment against ESD.

■ Make sure that the equipment and the floor are well grounded.

■ The equipment room is dust-proof.

■ Maintain an appropriate humidity and temperature.

■ Wear an ESD-preventive wrist strap and uniform when contacting the circuit

board.

■ Place the uninstalled circuit board on the antistatic workbench, with its face

upward, or put it into the static shielding bag.

■ When observing or removing the uninstalled circuit board, please touch the

edge of the circuit board, and avoid contacting the devices on it.

Requirements on

Electromagnetic

Environments

The interference sources, no matter where they come from, affect the routers with

capacitance coupling, inductance coupling, radiation of electromagnetic wave,

common impedance (including the grounding system) or conducting line (power

line, signal line and transmission line etc.). So the following should be considered:

■ Take effective measures to prevent the power system from being interfered

with by the power grid system.

■ Use an earthing system or lightning protection grounding different from that

for the power supply equipment and keep them as far as possible.

■ Keep the router far away from the radio launcher, radar launcher, and

high-frequency devices working in high current.

■ Use electromagnetic shielding when necessary.

Requirements on

Preventing Lightning

Although many measures have been taken to protect H3C MSR 20 Series from

lightning, if the lightning intensity exceeds a certain range, damage to the router

may still happen. To protect the router from lightning better, the following should

be considered:

■ Ensure the PGND wire of the chassis is well grounded.

■ Ensure the ground point of the socket of AC power supply is well grounded.

■ To enhance the lightning protection capability of the power supply, a lightning

arrester could be installed at the input end of the power supply.

■ As for the signal line outdoors to which the interface modules of H3C MSR 20

series routers are connected, such as ISDN line, telephone line, E1/T1 line, etc, a

special lightning arrester should be installed at the input end of the signal line

to enhance the lightning protection capability.

Checking the Rack When installing H3C MSR 20 Series Routers, observe the following:

■ There is spacing reserved at the air inlet and outlet in the router so as to

facilitate the radiation of the router cabinet.

■ Make sure that the rack has a good ventilation system.

■ Make sure that the rack is sturdy enough to support the weight of the device

and the installation accessories.

■ Make sure that the rack is well-grounded.

Safety Precautions Routers play a key role in data communications network. Please pay attention to

the following:

w

Warning: It indicates that this operation is incorrect and may seriously damage

the router or endanger the operator. Please follow the correct operation

procedures for sake of safety.

c

Caution: It indicates that during the installation and usage of the router, the

operation needs attention. If this operation is performed incorrectly, it might affect
