Overview

Introduction

MSR 20 Routers were self-developed for use on enterprise-level networks. Depending on the network size,

MSR 20 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 Routers are suitable

for the application on the carrier-level networks, such as telecom management networks and billing

networks. MSR 20 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 MSR 20 includes the following models:

• MSR 20-20

• MSR 20-21

• MSR 20-40

Router Model and Structure

The MSR 20 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.

is running.

• The CF card is used to store the software system and configuration file. The CF card LED blinks when the

system is readin

/writin

data from/to the CF card. In this case, do not remove the CF card, otherwise

hardware and software damage may occur.

• Do not unplug the USB device during USB data transmission; otherwise, data loss or even hardware

failures may occur.

• The USB interface does not support hot-swapping of USB modems from Sierra Wireless.

information about interface cards, refer to MSR Series Routers Interface Module Manual.

For the types of interface modules that each model of the MSR 20 routers can accommodate, refer to

Appendix A Interface Card and Interface Module Purchase Guide in the MSR Series Routers Interface

Module Manual.

SIC and DSIC Interface Cards

MSR series routers adopt modular design and support a wide range of optional SIC/DSIC interface

cards, providing various interfaces, such as synchronous/asynchronous serial interface, Ethernet

interface, E1/T1, ISDN BRI/PRI, ADSL, audio interface, and Layer 2 switching interface, and so on.

NOTE:

• For an MSR 20-40 router, 4FSW/1FEA/1GEC/1ADSL/1ADSL-I can only be installed in Slot 2 or Slo

• Currently, MSR 20 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.

Installation Preparations

Requirements on Environment

The MSR 20 routers are designed for indoor applications. 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 are shown in the following table:

Table 9 Temperature/humidity requirements in the equipment room

Temperature Relative humidity

0°C to 40°C (32°F to 104°F) 5% to 90% (non-condensing)

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:

Table 10 Limitation on dust content in equipment room

Diameter (μm) 0.5 1 3 5

Concentration

(particle/m³)

1.4 × 107

7 × 105

2.4 × 105

1.3 × 105

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

, H

S, NO

and CI

are given in the following table.

Requirements on Electrostatic Discharge Prevention

Although many antistatic considerations have been given to MSR 20, 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 MSR 20 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 MSR 20 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 MSR 20 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:

WARNING: 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.

CAUTION: indicates that during the installation and usage of the router, the operation needs

attention. If this operation is performed incorrectly, it might affect the operation of the router.

When installing or working on the router, you are recommended to:

• Keep the router far away from the heat sources and water/liquid.

• Make sure that the router has been correctly grounded.

• Wear an ESD-preventive wrist strap in installation and maintenance, making sure that the strap has

good skin contact.

• Do not hot swap the interface modules and interface cards of the router.

• Do not hot swap any cable.

• Correctly connect the interface cable for the router. Do not connect the telephone cable (including

the ISDN cable) to the AUX port or the console port.

• Use laser with caution. Do not directly stare into apertures or fiber-optic connectors that emit laser

radiation.

• Adopt uninterrupted power supply (UPS).
