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 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).

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.

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.

Token Ring Module LEDs
The 1E1R 2-slot network module has two Token Ring LEDs, labeled 16MBPS and IN-RING. The
16MBPS LED indicates a ring speed of 16 Mbps. If it is off, the ring speed is 4 Mbps.
The IN-RING LED indicates that the Token Ring interface is inserted into the ring. If it is off, the
interface is not inserted into the ring.
Timesaver When the IN-RING LED is off, you can unplug the Token Ring cable without causing
a problem on the ring.
Configuring the LAN Interfaces
Whenever you install a new interface, or if you want to change the configuration of an existing
interface, you must configure the interface. If you replace a module 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

16 WAN Card Slot Network Module Configuration Note
Configuring the LAN Interfaces
Timesaver Obtain this information from your system administrator or network plan before you
begin router configuration.
You can configure the new interface and other router parameters by using any of the following
methods:
•Configuration Mode (manual configuration)—Recommended if you are familiar with Cisco IOS
commands. Enter the commands at the prompt.
•AutoInstall—Recommended for automatic installation if another router running Cisco IOS
software is installed on the network. This configuration method must be set up by someone with
experience using Cisco IOS software.
•System Configuration Dialog (setup facility)—Recommended if you are not familiar with
Cisco IOS commands. You are prompted for each response.
These procedures are explained in the following sections. If you have questions or need help, refer
to the section “Obtaining Service and Support” later in this document for further information.
Configuration Mode
You can configure the Ethernet or Token Ring interfaces on your 2-slot network module manually,
by entering Cisco IOS commands on the command line. This method, called configuration mode,
provides the greatest power and flexibility.
Before you begin, disconnect all WAN cables from the router to keep it from trying to run the
AutoInstall process. The router tries to run AutoInstall whenever you power it ON if there is a WAN
connection on both ends and the router does not have a valid configuration file stored in nonvolative
random-access memory (NVRAM) (for instance, when you add a new interface). It can take several
minutes for the router to determine that AutoInstall is not connected to a remote Transmission
Control Protocol/Internet Protocol (TCP/IP) host.
To enter configuration mode, follow this procedure:
Step 1 Connect a console to the router. If you need instructions for connecting a console, refer
to the installation chapter of your router installation and configuration guide. Power up
the router.
Step 2 If the current configuration is no longer valid, after about a minute you see the following
prompt:
Would you like to enter the initial dialog? [yes]:
Answer no. You now enter the normal operating mode of the router.
Note If the current configuration is valid, you enter the normal operating mode
automatically.

WAN Card Slot Network Module Configuration Note 17
Configuring the LAN Interfaces
Step 3 After a few seconds you see the user EXEC prompt (Router>). Type enable and the
password to enter enable mode:
Router> enable
Password:
Configuration changes can be made only in enable mode. The prompt changes to the
privileged EXEC (enable) prompt (Router#):
Router#
Step 4 Enter the command config terminal to enter configuration mode:
Router# config terminal
Router(config)#
The router enters global configuration mode, indicated by the Router(config)# prompt.
Step 5 If you have not configured the router before, or want to change the configuration,
configure global parameters, passwords, network management, and routing protocols. In
this example, IP routing, AppleTalk routing, and Internetwork Packet Exchange (IPX)
routing are all enabled:
Router(config)# ip routing
Router(config)# appletalk routing
Router(config)# ipx routing
For complete information about global configuration commands, refer to the Cisco IOS
configuration guides and command references.
Step 6 Select the LAN interface to configure (using the keywords Ethernet or TokenRing):
Router(config)# interface ethernet 0/0
Router(config-if)#
The prompt changes again to show that you are in interface configuration mode.
Step 7 Configure routing protocols on the interface. (You must have previously enabled these
protocols as part of global configuration.) In this example, IP, AppleTalk, and IPX are
being configured on the interface:
Router(config-if)# ip address 172.16.74.3 255.255.255.0
Router(config-if)# appletalk static cable-range 3-3
Router(config-if)# appletalk zone ZZEth
Router(config-if)# ipx network B005
Step 8 If your router has more than one LAN interface, enter the exit command to return to the
Router(config)# prompt. Repeat Step 6 and Step 7 of this procedure to configure the next
LAN interface.
Step 9 When you are finished configuring interfaces, exit configuration mode and return to the
enable prompt by pressing Ctrl-Z. To see the current operating configuration, including
any changes you just made, enter the show running-config command:
Router# show running-config
To see the configuration currently stored in nonvolatile random-access memory
(NVRAM), enter the command show startup-config at the enable prompt.
Router# show startup-config

18 WAN Card Slot Network Module Configuration Note
Configuring the LAN Interfaces
Step 10 The results of the show running-config andshow startup-configcommands differ from
each other if you have made changes to the configuration, but have not yet written them
to NVRAM. To write your changes to NVRAM, making them permanent, enter the
command copy running-config startup-config at the enable prompt:
Router# copy running-config startup-config
Building configuration. . .
[OK]
Router#
The router is now configured to boot in the new configuration.
AutoInstall The AutoInstall process is designed to configure the router automatically after it connects to your
WAN. For AutoInstall to work properly, a TCP/IP host on your network must be configured to
provide the configuration files. The TCP/IP host can reside anywhere on the network if the following
two conditions are met:
•The host must be on the remote side of the router’s synchronous serial connection to the WAN.
•User Datagram Protocol (UDP) broadcasts to and from the router and the TCP/IP host must be
enabled.
This functionality is coordinated by your system administrator at the TCP/IP host site. You should
not try to use AutoInstall unless the required files have been installed on the TCP/IP host.
Follow this procedure to prepare your router for the AutoInstall process:
Step 1 Connect the router to the WAN.
Step 2 Turn ON power to the router.
The router loads the operating system image from Flash memory. If the remote end of the
WAN connection is connected and properly configured, the AutoInstall process begins.
Step 3 If AutoInstall succeeds, you should write the configuration data to the router’s NVRAM.
To do this, enter the copy running-config startup-config command at the Router#
prompt:
Router# copy running-config startup-config
Building configuration. . .
[OK]
Router#
Note This step saves the configuration settings that the AutoInstall process created. If
you do not do this, your new configuration will be lost the next time you boot the router.

Configuring the LAN Interfaces
System Configuration Dialog
You can configure the router manually using the System Configuration Dialog facility. Unlike
configuration mode, the System Configuration Dialog prompts you for each response.
Before you begin, disconnect all WAN cables from the router to keep it from trying to run the
AutoInstall process. The router tries to run AutoInstall whenever you power it ON if there is a WAN
connection on both ends and the router does not have a configuration file stored in NVRAM. It can
take several minutes for the router to determine that AutoInstall is not connected to a remote TCP/IP
host.
This section shows a sample configuration using the System Configuration Dialog. You should enter
values appropriate for your router and network.
Many prompts in the System Configuration Dialog include default answers, shown in square
brackets following the question. Enter your response, or press Return to accept the default answer.
You can request help at any time by entering a question mark (?) at a System Configuration Dialog
prompt.
Follow this procedure to configure the router using the System Configuration Dialog:
Step 1 Connect a console to the router. If you need instructions for connecting a console, refer
to your router installation and configuration guide. Power up the router.
Step 2 If the current configuration is no longer valid, after about a minute you see the following
prompt:
Would you like to enter the initial dialog? [yes]:
Press Return or enter yes to enter the System Configuration Dialog.
Note Youcan enter the SystemConfiguration Dialog at anytimefromtheenableprompt
(Router#) by entering the setup command.
Step 3 When the System Configuration Dialog asks whether you want to view the current
interface summary, press Return or enter yes:
First, would you like to see the current interface summary? [yes]:
Interface IP-Address OK? Method Status Protocol
First, would you like to see the current interface summary? [yes]:
Interface IP-Address OK? Method Status Protocol
Ethernet0/0 unassigned NO unset up down
Ethernet0/1 unassigned NO unset up down
Ethernet1/0 unassigned NO unset up down
TokenRing1/0 unassigned NO unset reset down
Step 4 If you have not configured the router before, or want to change the configuration, you
should now configure global parameters, passwords, network management, and routing
protocols. Refer to the procedures in the Cisco IOS configuration guides and command
references. Press Return if you want to accept the default values.

Configuring the LAN Interfaces
Step 5 The System Configuration Dialog prompts you to configure network interfaces. To
configure an Ethernet interface, press Return or enter yes when you reach a prompt
similar to this one, and then continue with Step 6:
Configuring interface Ethernet0/0:
Is this interface in use? [yes]:
To configure a Token Ring interface. pressReturn or enter yes when you reach a prompt
similar to this one, enter the ring speed, 4 or 16, and then continue with Step 6:
Configuring interface TokenRing1/0:
Is this interface in use? [yes]:
Tokenring ring speed (4 or 16) ? [16]:
Step 6 Determine which protocols you want on the LAN interface and enter the appropriate
responses. (You must have previously enabled these protocols as part of global
configuration.) In the following example, the interface is being configured for IP,
AppleTalk, and IPX:
Configure IP on this interface? [yes]:
IP address for this interface: 172.16.74.3
Number of bits in subnet field [8]: 8
Class B network is 172.16.0.0, 8 subnet bits; mask is
255.255.255.0
Configure AppleTalk on this interface? [no]: yes
Extended AppleTalk network? [no]: yes
AppleTalk starting cable range [0]: 3
AppleTalk ending cable range [1]: 3
AppleTalk zone name [myzone]: ZZEth
AppleTalk additional zone name:
AppleTalk additional zone name:
Configure IPX on this interface? [no]: yes
IPX network number [1]: B005
Step 7 If your router has more than one LAN interface, repeat Step 5 and Step 6 to configure the
next LAN interface.
Step 8 The configuration you entered is displayed as a command script and you are asked if you
want to use it. If you enter no, the information you just entered is discarded and you can
begin the configuration again. If you enter yes, the configuration is saved in the startup
configuration:
Use this configuration? [yes/no]: yes
Building configuration...
Use the enabled mode 'configure' command to modify this configuration.
Press RETURN to get started!
The configuration is saved. If you added an interface, the router reboots in the new
configuration when you press Return.
