Safety Recommendations

Caution To avoid damaging electrostatic discharge (ESD)-sensitive components, ensure that you

have discharged all static electricity from your body before opening the chassis. Before performing

procedures described in this document, review the next section, “Safety Recommendations.”

Safety Recommendations

Follow these guidelines to ensure general safety:

•Keep the chassis area clear and dust-free during and after installation.

•Put the removed chassis cover in a safe place.

•Keep tools away from walk areas where you or others could fall over them.

•Do not wear loose clothing that could get caught in the chassis. Fasten your tie or scarf and roll

up your sleeves.

•Wear safety glasses when working under any conditions that might be hazardous to your eyes.

•Do not perform any action that creates a potential hazard to people or makes equipment unsafe.

Warning The ISDN connection is regarded as a source of voltage that should be inaccessible to

user contact. Do not attempt to tamper with or open any public telephone operator (PTO)-provided

equipment or connection hardware. Any hardwired connection (other than by a nonremovable,

connect-one-time-only plug) must be made only by PTO staff or suitably trained engineers. (To see

translated versions of this warning, refer to the Regulatory Compliance and Safety Information

document that accompanied the router.)

Warning Network hazardous voltages are present in the BRI cable. If you detach the BRI cable,

detach the end away from the router ﬁrst to avoid possible electric shock. Network hazardous

voltages also are present on the system card in the area of the BRI port (RJ-45 connector), regardless

of when power is turned off. (To see translated versions of this warning, refer to the Regulatory

Compliance and Safety Information document that accompanied the router.)

Warning The Ethernet 10BaseT, Token Ring, serial, console, and auxiliary ports contain safety

extra-low voltage (SELV) circuits. BRI circuits are treated like telephone-network voltage (TNV)

circuits. Avoid connecting SELV circuits to TNV circuits. (To see translated versions of this

warning,refer totheRegulatory ComplianceandSafetyInformation document thataccompaniedthe

router.)

Safety with Electricity

Warning Before working on equipment that is connectedtopowerlines,removejewelry (including

rings, necklaces, and watches). Metal objects will heat up when connected to power and ground and

can cause serious burns or weld the metal object to the terminals. (To see translated versions of this

warning,refer totheRegulatory ComplianceandSafetyInformation document thataccompaniedthe

router.)

Safety Recommendations

Follow these guidelines when working on equipment powered by electricity:

•Locate the emergency power-OFF switch in the room in which you are working. Then, if an

electrical accident occurs, you can quickly shut the power OFF.

•Before working on the router, turn OFF the power and unplug the power cord.

•Disconnect all power before doing the following:

—Installing or removing a router chassis

—Working near power supplies

•Do not work alone if potentially hazardous conditions exist.

Warning Before opening the chassis, disconnect the telephone-network cables to avoid contact

with telephone-network voltages. (To see translated versions of this warning, refer to the Regulatory

Compliance and Safety Information document that accompanied the router.)

Warning Do not work on the system or connect or disconnect cables during periods of lightning

activity. (To see translated versions of this warning, refer to the Regulatory Compliance and Safety

Information document that accompanied the router.)

•Never assume that power is disconnected from a circuit. Always check.

Warning Do not touch the power supply when the power cord is connected. For systems with a

power switch, line voltages are present within the power supply even when the power switch is OFF

and the power cord is connected. For systems without a power switch, line voltages are present

within the power supply when the power cord is connected. (To see translated versions of this

warning,refer totheRegulatory ComplianceandSafetyInformation document thataccompaniedthe

router.)

•Look carefully for possible hazards in your work area, such as moist ﬂoors, ungrounded power

extension cables, and missing safety grounds.

•If an electrical accident occurs, proceed as follows:

—Use caution; do not become a victim yourself.

—Turn OFF power to the router.

—If possible, send another person to get medical aid. Otherwise, determine the condition of the

victim and then call for help.

—Determine if the person needs rescue breathing or external cardiac compressions; then take

appropriate action.

Preventing Electrostatic Discharge Damage

Electrostatic discharge (ESD) can damage equipment and impair electrical circuitry. It occurs when

electronic printed circuit cards are improperly handled and can result in complete or intermittent

failures. Always follow ESD prevention procedures when removing and replacing cards. Ensure that

the router chassis is electrically connected to earth ground. Wear an ESD-preventive wrist strap,

ensuring that it makes good skin contact. Connect the clip to an unpainted surface of the chassis

Required Tools and Equipment

frame to safely channel unwanted ESD voltages to ground. To properly guard against ESD damage

and shocks, the wrist strap and cord must operate effectively. If no wrist strap is available, ground

yourself by touching the metal part of the chassis.

Caution For safety, periodically check the resistance value of the antistatic strap, which should be

between 1 and 10 megohms (Mohm).

Required Tools and Equipment

You need the following tools and equipment to install a WAN interface card in a Cisco 3600 series

router:

•WAN interface card

•2-slot network module

•Number 1 Phillips screwdriver or small ﬂat-blade screwdriver

•ESD-preventive wrist strap

WAN Interface Card Slot Assignments

A 2-slot network module for Cisco 3600 series routers has two slots for installing WAN interface

cards. These slots are numbered W0, on the right, and W1, on the left. Some WAN interface cards

are keyed to be installed in slot W1 only. Cards that do not have a key ﬁt into either slot.

Both BRI WAN interface cards have a key and ﬁt into slot W1 only.

Termination Jumpers

The BRI S/T WAN interface card includes two termination jumpers, labeled J1 and J2. (See

Figure 3.) Before installing this card, make sure that these jumpers are set correctly for your

installation.

The jumpers are factory-conﬁgured in the B position (100 ohms termination). Keep the jumpers in

this position to use the BRI S/T WAN interface card in a point-to-point connection or as the last

device on the line of a passive-bus connection. Set the termination jumpers to the A position to use

the BRI S/T WAN interface card in a passive-bus connection where it is not the last device on the

line.

Installing a BRI WAN Interface Card in a Router

Figure 3 Termination Jumpers on the BRI S/T WAN Interface Card

Installing a BRI WAN Interface Card in a Router

Caution WAN interface cards do not support online insertion and removal (hot swap). Before

inserting a WAN interface card into a 2-slot network module that is already installed in the router

chassis, you must turn OFF electrical power and disconnect network cables.

The following instructions apply only to installing a WAN interface card in a 2-slot network module.

If you need to install the 2-slot module in a chassis slot, see your router installation and conﬁguration

guide.

You can install WAN interface cards either before or after mounting the router, whichever is more

convenient. You can install the card in the base module either before or after installing the base

module in the router chassis.

Note Do not install a BRI WAN interface card in the same chassis as an ISDN Primary Rate

Interface (PRI) network module. This conﬁguration is not supported.

Installing a BRI WAN Interface Card in a Router

Follow this procedure to install the WAN interface card in the 2-slot network module:

Step 1 If the 2-slot network module has already been installed in the router chassis, turn OFF

power to the router. However, to channel ESD voltages to ground, do not unplug the

power cable. Remove all network interface cables, including telephone cables, from the

rear panel.

The following warning applies to routers that use a DC power supply:

Warning Before performing any of the following procedures, ensure that power is removed from

the DC circuit. To ensure that all power is OFF, locate the circuit breaker on the panel board that

services the DC circuit, switch the circuit breaker to the OFF position, and tape the switch handle of

the circuit breaker in the OFF position. (To see translated versions of this warning, refer to the

Regulatory Compliance and Safety Information document that accompanied the router.)

Step 2 Using either a number 1 Phillips screwdriver or a small ﬂat-blade screwdriver, remove the

blank ﬁller panel from the slot in the 2-slot network module where you plan to install the

card. Save the blank panel for future use.

Step 3 Align the card with the guides in the 2-slot network module and slide it gently into the

WAN interface card slot. (See Figure 4.)

Connecting the WAN Interface Card to the Network

After you install the BRI WAN interface card in the WAN card slot network module and install the

network module in the router, use the appropriate cable to connect the BRI card to your WAN.

To connect a BRI S/T WAN interface card, use a straight-through RJ-45-to-RJ-45 cable to connect

the card’s RJ-45 connector to an NT1 device. (See Figure 6.)

To connect a BRI U WAN interface card, connect a straight-through RJ-45-to-RJ-45 cable directly

to your ISDN outlet. (See Figure 7.)

Caution To prevent damage to the router, make certain you connect the BRI cable to the BRI

connector only and not to any other RJ-45 connector.

Conﬁguring the BRI Interface

Whenever you install a new WAN interface card, or if you want to change the conﬁguration of an

existing interface, you must conﬁgure the interface. If you replace a card that was already

conﬁgured, the router recognizes it and brings up the interface in the existing conﬁguration.

Before you conﬁgure an interface, have the following information available:

•Protocols you plan to route on the new interface

•IP addresses, subnet masks, network numbers, zones, or other information related to the routing

protocol

Timesaver Obtain this information from your system administrator or network plan before you

begin router conﬁguration.
