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)

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.
