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

document.

Software Requirements

The minimum version of Cisco Internetwork Operating System (Cisco IOS) software needed for

2-slot network modules is 11.1(6)AAS.

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.

4WAN Card Slot Network Module Conﬁguration Note

Safety Recommendations

•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 the equipment

unsafe.

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,refertotheRegulatoryComplianceandSafetyInformationdocumentthataccompaniedthe

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 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.)

Safety with Electricity

Warning Before workingon equipment that is connected to power lines, 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,refertotheRegulatoryComplianceandSafetyInformationdocumentthataccompaniedthe

router.)

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.

WAN Card Slot Network Module Configuration Note 5

Safety Recommendations

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,refertotheRegulatoryComplianceandSafetyInformationdocumentthataccompaniedthe

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

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).

6WAN Card Slot Network Module Conﬁguration Note

Required Tools and Equipment

You need the following tools and equipment to install a network module in a Cisco 3600 series

chassis slot:

•Network module

•Number 1 Phillips screwdriver or small ﬂat-blade screwdriver

•ESD-preventive wrist strap

Installing a 2-Slot Network Module in a Chassis Slot

Caution Network modules do not support online insertion and removal (hot swap). To avoid

damaging the module, before you insert a network module into a chassis slot, you must turn OFF

electrical power and disconnect network cables.

The following instructions apply only to installing network modules in a chassis slot. To install a

WAN interface card in a network module, see the conﬁguration note for the WAN interface card.

You can install network modules in the chassis either before or after mounting the router, whichever

is more convenient.

Follow this procedure to install a network module:

Step 1 Turn OFF electrical 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 chassis slot where you plan to install the module. Save the

blank panel for future use.

Step 3 Align the network module with the guides in the chassis and slide it gently into the slot.

(See Figure 4.)

Network Module Connectors

The number and type of connectors on a 2-slot network module depend on the type of module.

1E 2-Slot Network Module

The 1E 2-slot network module has one Ethernet attachment unit interface (AUI) DB-15 connector

and one 10BaseT RJ-45 connector. (See Figure 7.) Only one of these two connectors can be active

at a time. The active port is identiﬁed in software by port type (Ethernet), the module’s slot number,

and port number 0.

The module detects the type of network connection automatically, and you do not need to select the

media type in software. If cables are plugged into both ports, the 10BaseT connection is selected.

Figure 7 1E 2-Slot Network Module

2E 2-Slot Network Module

The 2E 2-slot network module has ports for two Ethernet connections. (See Figure 8.)

Ethernetport 0 uses either theAUI (DB-15)connector on theright or the10BaseT (RJ-45) connector

in the center, but only one at a time. Ethernet port 1 uses the 10BaseT connector on the left. This port

does not provide an AUI connector. Ports are identiﬁed in software by port type (Ethernet), the

module’s slot number, and the port number.

The module detects the type of network connection automatically, and you do not need to select the

media type in software. If cables are plugged into both ports, the 10BaseT connection is selected.

10 WAN Card Slot Network Module Conﬁguration Note

Connecting Ethernet Ports

On 1-Ethernet network modules and on Ethernet port 0 (the right-hand port) of 2-Ethernet network

modules, connect either the Ethernet AUI or the 10BaseT connector, but not both at the same time.

Ethernet port 1 (the left-hand port) of 2-Ethernet network modules provides only a 10BaseT

connector.

AUI ConnectionsUse an Ethernet AUI cable to connect the AUI port on an Ethernet network module to an Ethernet

transceiver. The female end of the AUI cable mates with the slide-latch connector of the transceiver

cable. (See Figure 10.)

Figure 10 Connecting an Ethernet AUI Port to a Transceiver

If the transceiver cable has thumbscrew connectors, you can connect it directly to the AUI port by

replacing the AUI port slide latch with a jackscrew (provided in a separate bag).

10BaseT Connections

Use an Ethernet 10BaseT cable to connect the 10BaseT port on an Ethernet network module to a hub

or other network device. Figure 11 shows the 10BaseT port on an Ethernet network module

connected to a hub.
