1 Overview
Introduction
MSR 20 Series Routers were self-developed by our company. 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 MSR 20 series includes the following models:
z MSR 20-20
z MSR 20-21
z MSR 20-40
Router Model and Structure
The MSR 20 Series Routers include MSR 20-20, MSR 20-21, and MSR 20-40. These three model s 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 detail s about these three models.

Generic Modules
The MSR 20 series is available with generic modules such a s SIC interface card and ESM. For detailed
information about interface cards, refer to MSR Series Routers Interface Card and 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 interfa c e, and Layer 2 switching interface, and so on.
1-7
z For an MSR 20-40 router, 4FSW/1FEA/1GEC/1ADSL/1ADSL-I can only be installed in Slot 2 or
Slot 4.
z 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
z High-performance network data encryption ESM module (ESM-ANDE)
z 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 p a ckets 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.

2 Installation Preparations
Requirements on Environment
MSR 20 Series must be used indoors. To ensure the normal operation and prolong their service life, the
following requirements for inst allation site must be met.
Requirements on Temperature/Humidity
To ensure the normal operation and prolong their service life, certain requirement s on temperat ure and
humidity in the equipment room shall be met. If the relative humidity is too high, the insulation m aterials
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 compon ents. 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 route r 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:
Table 2-1 Temperature/humidity requirements in the equipment room
Temperature Relative Humidity
0°C to 40°C (32°F to 104°F)
Requirements on Cleanness
Dust is harmful to the safe operation of the Router. Dust on the chassis may result in static ab so rption,
thus causing poor contact of the metal connection compon ents or points. Espe cially 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 2-2 Limitation on dust content in equipment room
Diameter (μm)
Concentration

1.4 × 107
5% to 90% (noncondensing)
0.5 1 3 5
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 part s. The specific limit s of these harmful g ases as SO
and CI2 are given in the following table.

Requirements on Electrostatic Discharge Prevention
Although many antistatic considerations have been given to 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.
z Make sure that the equipment and the floor are well grounded.
z The equipment room is dust-proof.
z Maintain an appropriate humidity and temperature.
z Wear an ESD-preventive wrist strap and uniform when contacting the circuit board.
z Place the uninstalled circuit board on the antistatic workbench, with its face upward, or put it into
the static shielding bag.
z 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, af fect the routers with cap acitance couplin g,
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:
z Take effective measures to prevent the power system from being interfered with by the power grid
system.
z Use an earthing system or lightning protection grounding different from that for the power supply
equipment and keep them as far as possible.
z Keep the router far away from the radio launcher, radar launcher, and high-frequency devices
working in high current.
z Use electromagnetic shielding when necessary.
Requirements on Preventing Lightning
Although many measures have been taken to protect 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:
z Ensure the PGND wire of the chassis is well grounded.
2-2
z Ensure the ground point of the socket of AC power supply is well grounded.
z To enhance the lightning protection capability of the power supply, a lightning arrester could be
installed at the input end of the power supply.
z As for the signal line outdoors to which the interface modules of 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 MSR 20 Series Routers, observe the following:
z There is spacing reserved at the air inlet and outlet in the router so as to facilitate the radiation of
the router cabinet.
z Make sure that the rack has a good ventilation system.
z Make sure that the rack is sturdy enough to support the weight of the device and the installation
accessories.
z 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:
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.
It 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:
z Keep the router far away from the heat sources and water/liquid.
z Make sure that the router has been correctly grounded.
z Wear an ESD-preventive wris t strap in installation and maintenance, making sure that the strap
has good skin contact.
z Do not hot swap the interface modules and interface cards of the router.
z Do not hot swap any cable.
z 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.
z Use laser with caution. Do not directly stare into apertures or fiber-optic connectors that emit laser
radiation.
z Adopt uninterrupted power supply (UPS).
