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:

zMSR 20-20

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 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:

Table 2-1 Temperature/humidity requirements in the equipment room

Temperature	Relative Humidity
0°C to 40°C (32°F to 104°F)	5% to 90% (noncondensing)

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 2-2 Limitation on dust content in equipment room

	Diameter (μm)	0.5		1		3		5
	Concentration	1.4 × 107		7 × 105		2.4 × 105		1.3 × 105
	(particle/m³)

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 SO2, H2S, NO2, NH3 and CI2 are given in the following table.

2-1

Table 2-3 Harmful limits in equipment room

Gas	Max (mg/m3)
SO2	0.2
H2S	0.006
NH3	0.05
CI2	0.01

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.

zMake sure that the equipment and the floor are well grounded.

zThe equipment room is dust-proof.

zMaintain an appropriate humidity and temperature.

zWear an ESD-preventive wrist strap and uniform when contacting the circuit board.

zPlace the uninstalled circuit board on the antistatic workbench, with its face upward, or put it into the static shielding bag.

zWhen 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:

zTake effective measures to prevent the power system from being interfered with by the power grid system.

zUse an earthing system or lightning protection grounding different from that for the power supply equipment and keep them as far as possible.

zKeep the router far away from the radio launcher, radar launcher, and high-frequency devices working in high current.

zUse 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:

zEnsure the PGND wire of the chassis is well grounded.

2-2

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

zTo enhance the lightning protection capability of the power supply, a lightning arrester could be installed at the input end of the power supply.

zAs 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:

zThere is spacing reserved at the air inlet and outlet in the router so as to facilitate the radiation of the router cabinet.

zMake sure that the rack has a good ventilation system.

zMake sure that the rack is sturdy enough to support the weight of the device and the installation accessories.

zMake 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:

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

zMake sure that the router has been correctly grounded.

zWear an ESD-preventive wrist strap in installation and maintenance, making sure that the strap has good skin contact.

zDo not hot swap the interface modules and interface cards of the router.

zDo not hot swap any cable.

zCorrectly 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.

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

zAdopt uninterrupted power supply (UPS).
