Preparing for installation

Safety recommendations

Safety symbols

When reading this document, note the following symbols:

WARNING means an alert that calls attention to important information that if not understood or

followed can result in personal injury.

CAUTION means an alert that calls attention to important information that if not understood or

followed can result in data loss, data corruption, or damage to hardware or software.

General safety recommendations

• Keep the chassis and installation tools away from walk areas.

• Make sure that the ground is dry and flat and anti-slip measures are in place.

• Unplug all the external cables (including power cables) before moving the chassis.

Safety with electricity

• Locate the emergency power-off switch in the room before installation. Shut the power off at once in

case accident occurs.

• Make sure that the router has been correctly grounded.

• Do not open or close the chassis cover when the router is powered on.

• Connect the interface cables for the router correctly.

• Use an uninterrupted power supply (UPS).

• If there are two power inputs, disconnect the two power inputs to power off the router.

• Do not work alone when the router has power.

• Always check that the power has been disconnected.

Examining the installation site

The HP MSR20-1X router can only be used indoors. To ensure that the router works properly and to
prolong its service lifetime, the installation site must meet the following requirements:

• Temperature and humidity

• Cleanness

• Cooling system

• ESD prevention

• EMI

• Lightning protection

Temperature and humidity

You must maintain a proper temperature and humidity in the equipment room. Long-term high humidity
may lead to bad insulation, electricity leakage, mechanical property changes, and metal corrosion.
However, if the relative humidity is too low, captive screws may become loose as the result of contraction
of insulation washers and static electricity may be produced in a dry environment to jeopardize the
circuits on the device. A high temperature is the most undesirable condition, because it accelerates the
aging of insulation materials and significantly lowers reliability and service life of the router.

For the temperature and humidity requirements of the router, see Table 1.

Table 1 Temperature/humidity requirements

Tem

erature Relative humidit

0°C to 40°C (32°F to 104°F) 5% to 90%

Cleanness

Dust buildup on the chassis may result in electrostatic adsorption, which causes poor contact of metal
components and contact points, especially when indoor relative humidity is low. In the worst case,
electrostatic adsorption can cause communication failure.

articles/cu m)

The equipment room must also meet strict limits on salts, acids, and sulfides to eliminate corrosion and
premature aging of components, as shown in Table 3.

Cooling system

• Make sure there is enough space (greater than 10 cm (3.94 in)) around the air intake and outlet

vents on the router for good ventilation.

• Make sure the installation site has a good cooling system.

ESD prevention

g

To prevent electrostatic discharge (ESD), note the following guidelines:

• Make sure that the router and the floor are well grounded.

• Take dust-proof measures for the equipment room.

• Maintain the humidity and temperature at a proper level.

• Always wear an ESD-preventive wrist strap when touching a circuit board or transceiver module.

To use the ESD-preventive wrist strap:

1. Wear the wrist strap on your wrist.

2. Lock the wrist strap tight around your wrist to keep good contact with the skin.

3. Insert the ESD-preventive wrist strap into the specially designed hole on the router chassis or attach

it to the grounding screw of the chassis with the alligator clips.

4. Make sure that the rack is well grounded.

Figure 19 Use an ESD-preventive wrist strap

EMI

(1) ESD-preventive wrist strap (2) Lock (3) Alligator clip

CAUTION:

• Check the resistance of the ESD-preventive wrist strap for safety. The resistance readin

should be in the

range of 1 to 10 megohm (Mohm) between human body and the ground.

• No ESD-preventive wrist strap is provided with the HP MSR20-1X router. Prepare it yourself.

All electromagnetic interference (EMI) sources, from outside or inside of the router and application system,
adversely affect the router in a conduction pattern of capacitance coupling, inductance coupling,
electromagnetic wave radiation, or common impedance (including grounding system) coupling. To
prevent EMI, perform the following steps:

• Take measures against interference from the power grid.

• Do not use the router together with the grounding equipment or light-prevention equipment of

power equipment, and keep the router far away from them.

• Keep the router far away from high-power radio launchers, radars, and equipment with high

frequency or high current.

10

NOTE:

Use electromagnetic shielding when necessary.

Lightning protection

To protect the router from lightning better, do as follows:

• Make sure the grounding cable of the chassis is well grounded.

• Make sure the grounding terminal of the AC power receptacle is well grounded.

• Install a lightning arrester at the input end of the power supply to enhance the lightning protection

capability of the power supply.

• Install a special lightning arrester at the input end of outdoor signal lines (for example, E1/T1 line)

to which interface modules of the router are connected to enhance the lightning protection
capability.

Rack-mounting

Before mounting the router in a standard 19-inch rack, adhere to the following requirements:

• The rack has a good ventilation system.

• The rack is sturdy enough to support the router and installation accessories.

• Make sure that the size of the rack is appropriate for the router, and that there is enough clearance

around the left and right sides of the router for heat dissipation.

• For heat dissipation and device maintenance, make sure the front and rear of the rack should be at

least 0.8 m (2.62 ft) away from walls or other devices, and that the headroom in the equipment
room should be no less than 3 m (9.84 ft).

Configuration system problems

If the configuration environment setup is correct, the configuration terminal displays boot information
when the router is powered on. If the setup is incorrect, the configuration terminal displays nothing or
garbled text.

No terminal display

If the configuration terminal displays nothing when the router is powered on, follow these steps to
troubleshoot the failure:

1. Check the following items.

{ The power supply system works properly.

{ The console cable is properly connected.

2. If no problem is found, check the following reasons that may apply:

36

{ The console cable is connected to an incorrect serial port (the serial port in use is not the one set

on the terminal).

{ The properties of the terminal are incorrect. You must configure the console terminal as follows:

set Bits per second to 9600, Data bits to 8, Parity to None, Stop bits to 1, Flow control to None,
and Terminal Emulation to VT100.

{ The console cable fails.

Garbled terminal display

If terminal display is garbled, make sure that the Data bits field is set to 8 for the console terminal. If the
Data bits field is set to 5 or 6, the console terminal will display garbled characters.

No response from the serial port

If the serial port gives no response, check that the serial cable is in good condition and serial port settings
are correct.

Reset button

The MSR20-1X has a Reset button to restart the system and restore the factory defaults.

• If you press the button shortly, the router is restarted.

• If you press the button for at least five seconds, the router is restarted and restores to the factory

defaults.

Appendix C Setting the fixed E1 port impedance

CAUTION:

The DIP switches are located at the mother board inside the router chassis. To operate the DIP switches,
you must open the router chassis. For more information, see the chapter “Installin
modules.”

By default, the impedance of the fixed E1 port on MSR20-12/20-12-W is 75 ohms. By using the internal
DIP switches, you can change the interface impedance from 75 ohms to 120 ohms.

NOTE:

• HP recommends that you select the DIP switch of the fixed E1 port in this way: when you connect 75-ohm

cable, flip BIT1-8 to ON; when you connect 120-ohm cable, flip BIT1-8 to OFF.

• By default, all of the DIP switches are factory-configured to ON. In other words, the impedance of E1

port is 75 ohms.

Appendix D Arranging slots and numbering interfaces

Slot arrangement

The router provides SIC slots. You can expand two SIC slots to one DSIC slot by removing the slot divider.

All fixed ports on the MSR20-1X belong to slot 0.

Table 16 MSR20-1X slot arrangement

Model Slot arran

All models

—SIC slot

—DSIC slot

Numbering interfaces

The interfaces of the router are numbered in the form of interface-type X/Y,

Where,

• interface-type—Type of an interface such as serial, asynchronous, or Ethernet port.

• X—Number of the slot where an interface module resides.

• Y—Sequence number of an interface on an interface module.

Interfaces on the same interface module have the same slot number X, and are numbered from 0 in
ascending order from left to right when you face the interface module.

• For example, the fixed WAN port on the MSR20-1X is nubmered Ethernet 0/0, the four fixed

Ethernet LAN ports are numbered Ethernet 0/1, Ethernet 0/2, Ethernet 0/3, and Ethernet 0/4.

ement

• The interface module SIC-4FSW is installed in slot 1. The Ethernet ports on the interface module are

numbered from left to right: Ethernet 1/0, Ethernet 1/1, Ethernet 1/2, and Ethernet 1/3.
