Overview

Introduction

MSR 50 Routers were self-developed by our company for use on enterprise-level networks. Depending on
the network size, MSR 50 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 50
Routers are suitable for the application on the carrier-level networks, such as telecom management
networks and billing networks. MSR 50 Routers adopt modular design and support a wide range of
optional interface cards and service modules, including flexible interface card (FIC), smart interface card
(SIC), multi-service card A (MSCA), multi-service card B (MSCB), enhanced service module (ESM), voice
processing module (VPM) and voice co-processing module (VCPM).

The MSR 50-40 routers are 3U in height and the MSR 50-60 are 4U in height. Slot 0 provided on the
front panel of both the two models is for the main control board, which can be MPUF or MPU-G2
respectively. MSCA or MSCB can be installed in the MSC slot provided on the backplane to provide a
variety of security and voice services, where MSCA works in conjunction with MPUF while MSCB works
with MPU-G2.

Base on power supply mode, the MSR 50-40 and MSR 50-60 each have three models: AC, DC, and PoE
power supply. You can choose to use a DC or AC power supply unit (PSU) as the system power supply,
or install two AC or two DC PSUs to form 1+1 redundancy backup. You can also install a PoE power
module to work in conjunction with the AC or DC PSU to provide remote power supply for powered
devices (PDs).

The PSUs, fan trays, and FICs of MSR 50 routers are all hot swappable.

Currently, the MSR 50 include these models:

• MSR 50-40

• MSR 50-60

NOTE:

• Boot ROM stores the Bootstrap for booting the router.

• Communication data between the system and the CPU is stored in the memory when the system is

running.

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

system is reading/writing data from/to the CF card. In this case, do not remove the CF card; otherwise
hardware and software damage may occur.

The figures above illustrate the components of a router with MPUF installed. No SIC slots are provided if
an MPU-G2 is applied on the router.

Generic Modules

The MSR 50 is available with generic modules such as SIC and FIC interface cards. For detailed
information about interface cards, refer to MSR Series Routers Interface Module Manual.

For the types of interface modules that each model of the MSR 50 routers can accommodate, refer to

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

Currently, the MSR 50 routers primarily support the main boards MPUF and MPU-G2. See details as
follows.

MPUF/MPU-G2

Functions

As the core of the router, the MPUF/MPU-G2 functions to process protocols, forward low-speed packets,
govern interfaces, and detect faults. You can gather information about the operating state of FAN module,
PSU, and system by reading their corresponding LEDs on the main control board; alternatively, you can
monitor state using a network management system. In addition, the main control board provides a
hardware reset button: RESET. Each MPUF provides four SIC slots for extending the access capabilities.
An MPU-G2 delivers improved process capabilities without offering any SIC slots.

PSU

Functions

The power supply system of the MSR 50 can work in either single-power or dual-power mode. In
dual-power mode, the two PSUs (DC-input or AC-input) function in redundancy backup mode. That
means, when a PSU fails or its power supply is disconnected, another PSU can still work and supply all
the power required by the system.

You can connect a PSU to the backplane by inserting it from the rear of the router chassis. It is hot
swappable and its switchover does not affect the ongoing system operation.

NOTE:

• When installing your router in a communications equipment room, ensure that the AC power

distribution cabinet can provide a li

g

htning protection box or arrester against the current of 20 KA and

above.

• MPU-G2 does not support any PoE power module.

FAN Module

Functions

The MSR 50-40 is configured with six fans; the MSR 50-60 is configured with eight fans. These fans are
working in pairs and the two fans in each pair are working in redundancy. When all these fans are
working normally, the operating temperature of the system can be maintained between 0°C and 55°C
(32°F to 131°F). As the failure of a fan does not affect the operation of other fans, the normal operating

14

temperature of the system can maintain. The routing speed of the fans is adjusted by the fan controller on
the main control board and between 50% and 100% depending on the system temperature. When the
system temperature rises above the high-temperature threshold set by the fan controller, the fans are
rotating at full speed (100%); when the system temperature drops below the low-temperature threshold,
the fans are rotating only at half of the speed (50%). When a fan stops rotating, the fan controller alarms.
The alarm and state LEDs of the FAN are located on the front panel of MPUF.

Appearance

The following figure shows a FAN module, taking MSR 50-60 for example.

SIC/DSIC and FIC/DFIC Interface Cards

MSR 50 routers adopt modular design and support a wide range of optional SIC/DSIC and FIC/DFIC
interface cards, providing various interfaces, such as synchronous/asynchronous serial interface,
Ethernet interface, E1/T1, ISDN BRI/PRI, ADSL, audio interface, Layer 2 switching interface, and so on.

For details about the interface cards, refer to MSR Series Routers Interface Module Manual.

NOTE:

• For an MSR 50 router, SIC-4FSW/1FEA/1GEC/1ADSL/1ADSL-I can only be installed in Slot 2 or Slo

t

4 on the MPUF.

• Interface cards that support PoE can be used for remote power supply only if they are installed on the

PoE models; otherwise, the interface cards that support PoE can only function as normal switching
modules if they are used on non-PoE models.

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 50 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 50 are shown in the following table:

Table 12 Temperature/humidity requirements in the equipment room

Temperature Relative humidity (noncondensing)

0°C to 40°C (32°F to 104°F) 5% to 90%

Requirements on Cleanness

Dust is harmful to the safe operation of the Router. Dust on the chassis may resu lt in static absorption, t hus
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 13 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

2

, H2S, NO2,

NH

3

and CI2 are given in the following table.

SO2 0.2

H2S 0.006

NH3 0.05

Cl2 0.01

Requirements on Electrostatic Discharge Prevention

Although many antistatic considerations have been given to MSR 50, 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 the 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 removed circuit board on the antistatic workbench, with its face upward, or put it into the

static shielding bag.

• When observing or moving the removed 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 50 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.

18

• 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 50 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.

Requirements on Workbench

When installing MSR 50 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

When reading this manual, 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).
