•If an electrical accident occurs, proceed as follows:
–Use caution; do not become a victim yourself.
–Turn off power to the room using the emergency power-off switch.
–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 can damage equipment and impair electrical circuitry. Electrostatic discharge occurs when electronic printed circuit cards, such as those used in Cisco network modules, are improperly handled and can result in complete or intermittent equipment failure. Always observe the following electrostatic discharge damage (ESD) prevention procedures when installing, removing, and replacing Cisco network modules, Cisco interface cards, Cisco expansion modules, or other electronic printed circuit cards:
•Make sure that the router chassis is electrically connected to earth ground.
•Wear an ESD-preventive wrist strap, and make sure that it makes good contact with your skin.
•Connect the wrist strap clip to an unpainted portion of the chassis frame to channel unwanted ESD voltages to ground.
Caution The wrist strap and clip must be used correctly to ensure proper ESD protection. Periodically confirm that the resistance value of the ESD-preventive wrist strap is between 1 and 10 megohms (Mohm).
•If no wrist strap is available, ground yourself by touching the metal part of the router chassis.
General Maintenance Guidelines for Cisco Network Modules
The following maintenance guidelines apply to Cisco network modules:
•Keep the router chassis area clear and dust-free during and after installation.
•If you remove the chassis cover for any reason, store it in a safe place.
•Do not perform any action that creates a hazard to people or makes equipment unsafe.
•Keep walk areas clear to prevent falls or damage to equipment.
•Follow installation and maintenance procedures as documented by Cisco Systems, Inc.

Replacing Network Modules in Cisco Access Routers with Online Insertion and Removal Support
Online insertion and removal (OIR) provides uninterrupted network operation, maintains routing information, and ensures session preservation. The following Cisco access routers support OIR for similar network modules:
•Cisco 3660 routers
•Cisco 3745 routers
•Cisco 3845 routers
Caution These Cisco access routers support OIR with similar network modules only. If you remove a network module, install the same model network module in its place. For 1- or 2-slot network modules, you must install the same network module and interface card combination.
Caution Do not perform OIR on interface cards in 1- or 2-slot network modules. To avoid damage to the interface card and to the network module, turn off electrical power and disconnect network cables before inserting an interface card into a network module slot.
OIR procedures require some interaction with Cisco IOS software. For more information on Cisco IOS software-related tasks, see documents listed in the "Where to Go Next" section.
Tip Not all Cisco network modules and Cisco interface cards support OIR. Check the hardware documentation specific to your network module or interface card to confirm OIR support before starting OIR procedures.
To replace a network module with OIR support from a Cisco access router, perform the following steps:
Step 1 Initiate a console session with your Cisco access router.
Step 2 Enter interface configuration mode and shut down each interface on the network module you plan to remove. (See Example 2-1.)
Example 2-1 Shutting Down Interfaces on Cisco Network Modules
Router(config)# interface fastethernet 1/0
Router(config-if)# shutdown
Tip To see information for all interfaces available on the network module, use the show interfaces command.
Step 3 Repeat Step 2 for each interface on the network module.
Step 4 Unplug all cables from the network module.
Timesaver To make it easier to work with network cables, label the cables or prepare a network cabling diagram before removing network interface cables from the network module.
Step 5 Remove the network module as described in the "Removing or Replacing Single-Wide, Extended Single-Wide, and Extension Voice Network Modules from Cisco Access Routers" and "Removing or Replacing Double-Wide and Extended Double-Wide Network Modules in Cisco Access Routers" sections.
Step 6 Install a replacement network module. If you are not planning to install another network module at this time, install a blank faceplate over the network module slot. (See the "Installing Blank Faceplates on Cisco Access Routers" section.)
Step 7 Connect the cables removed from the previous network module.
Step 8 Confirm that the network module LEDs come on, and that the Active/Ready LEDs on the front panel of the router also come on. For further information on network module LEDs, see the chapter describing your specific network module.
Step 9 Initiate a console session with your Cisco access router.
Step 10 Enter interface configuration mode and activate each interface on the network module, as shown in Example 2-2.
Example 2-2 Activating Interfaces on Cisco Network Modules
Router(config)# interface fastethernet 1/0
Router(config-if)# no shutdown
Step 11 Repeat Step 10 for every interface on the network module.
Removing or Replacing Application and Service Network Modules
Application and service network modules use hard disks and require special software procedures prior to removal or replacement.
Caution Online removal of disks without proper shutdown can result in file system corruption and might render the disk unusable. The operating system on the applications or services network module must be shut down in an orderly fashion before the network module can be removed.
To perform online removal of a Cisco application and service network module and insertion of a replacement, follow these steps with the router in privileged EXEC mode:
Step 1 Initiate an application and service network module console session using the following command:
Router# service-module service-engine slot/port session
Trying 10.10.10.1, 2129 ... Open
SE-netmodule> enable
Password:
SE-netmodule#
SE-netmodule con now available
Press RETURN to get started!
SE-netmodule> enable
Password:
SE-netmodule#
Timesaver Cisco application and service network modules use a blank password. Press Enter at the password prompt.
Step 2 Save the running configuration for the network module by entering the following command from the SE-netmodule prompt:
SE-netmodule# copy running-config ftp:
Address or name or remote host? username/password/remote host
Destination filename? filename
Step 3 Exit the network module console session by pressing Ctrl-Shift-6, followed by x.
Step 4 On the router, clear the network module console session with the following command:
Router# service-module service-engine slot/port session clear
Step 5 Perform a graceful halt of the network module disk drive with the following command:
Router# service-module service-engine slot/port shutdown
Step 6 Remove the network module, using the procedure described in the "Removing or Replacing Single-Wide, Extended Single-Wide, and Extension Voice Network Modules from Cisco Access Routers" section.
Step 7 Install the replacement network module, using the procedure described in the "Installing Cisco Network Modules in Cisco Access Routers" section.
Step 8 Check that the network module LEDs come on and that the Active/Ready LEDs on the router front panel also come on. This inspection ensures that connections are secure and that the new unit is operational.
Step 9 Initiate a network module console session with the following command:
Router# service-module service-engine slot/port session
Trying 10.10.10.1, 2129 ... Open
SE-netmodule con now available
Press RETURN to get started!
SE-netmodule> enable
SE-netmodule#
Step 10 Restore the running configuration for the network module with the following command from the SE-netmodule prompt:
SE-netmodule# copy ftp: running-config
Address or name or remote host? username/password/remote host
Source filename? filename
Step 11 Exit the network module console session by pressing Ctrl-Shift-6, followed by x.
Step 12 On the router, clear the console session using the following command:
Router# service-module service-engine slot/port session clear
Installing Cisco Interface Cards in 1- or 2-Slot Network Modules
Some network modules have one or two interface card slots, which support a variety of voice and data interface cards. (See Table 1-2 on page 1-8 for more information.)
Note Do not install an ISDN BRI WAN interface card or an ISDN BRI network module in the same chassis as an ISDN PRI network module unless you are using Cisco IOS Release 11.3(3)T or later.
Note Do not install newer BRI WAN interface cards in the same network module as older BRI WAN interface cards. To identify newer BRI WAN interface cards, examine the B-channel LEDs. Newer BRI WAN interface cards have B-channel LEDs that are arranged horizontally. Older BRI WAN interface cards have B-channel LEDs that are arranged vertically.
To install an interface card in a 1- or 2-slot network module, perform the following steps:
Step 1 Turn off electrical power to the router. Leave the power cable plugged in to channel ESD voltages to ground.
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. Statement 7
Warning To avoid electric shock, do not insert a WAN or voice interface card into a 2-slot module while power is on or network cables are connected. Statement 68
Caution Do not perform OIR on interface cards in 1- or 2-slot network modules. To avoid damage to the interface card and to the network module, turn off electrical power and disconnect network cables before inserting an interface card into a network module slot.
Step 2 Remove all network cables, including telephone cables, from the rear panel of the router.
Timesaver To make it easier to work with network cables, label the cables or prepare a network cabling diagram before removing network interface cables from the network module.
Step 3 Using a number 1 Phillips or flat-blade screwdriver, loosen the screws on the blank interface card faceplate. (See Figure 2-16.) Remove the blank faceplate.
Figure 2-16 Blank Interface Card Faceplate
Tip Save blank interface card faceplates for future use.
Step 4 Align the interface card with the guides in the slot on the network module and slide it gently into place until the edge connector is seated into the connector on the module. (See Figure 2-17.)

Step 5 Using a number 1 Phillips or flat-blade screwdriver, tighten the captive mounting screws into the holes on the network module faceplate.
Step 6 Reinstall the network interface cables and power up the router.
The following warning applies to routers that use a DC power supply:
Warning After wiring the DC power supply, remove the tape from the circuit breaker switch handle and reinstate power by moving the handle of the circuit breaker to the ON position. Statement 8
Installing Other Accessories on Cisco Network Modules
Some Cisco network modules support a variety of additional modules, such as gigabit interface converters (GBICs) and small form-factor pluggable modules (SFPs).
Installing and Removing GBICs
To install a GBIC, perform the following steps:
Warning Because invisible laser radiation may be emitted from the aperture of the port when no fiber cable is connected, avoid exposure to laser radiation and do not stare into open apertures. Statement 125
Step 1 (For optical GBICs) Confirm insertion of plugs into the SC connectors on the GBIC to prevent laser emissions.
Step 2 Hold down the clips on the side of the GBIC while inserting the GBIC into the GBIC slot in the network module faceplate. (See Figure 2-18.)
Figure 2-18 Installing a GBIC into a Network Module
Step 3 Release the side clips on the GBIC to lock the GBIC in place.
Step 4 Confirm that the GBIC is seated.
Caution Do not remove the optical port plugs used on the GBIC until you are ready to connect cabling to the network module.
Step 5 (For optical GBICs) Remove the plugs from the SC connectors on the GBIC.
Timesaver If installing the GBIC in a loose network module, install the network module (see the "Installing Cisco Network Modules in Cisco Access Routers" section) before connecting the network module to the network.
To remove a GBIC, perform the following steps:
Warning Because invisible laser radiation may be emitted from the aperture of the port when no fiber cable is connected, avoid exposure to laser radiation and do not stare into open apertures. Statement 125
Step 1 Disconnect the GBIC from the network.
Step 2 (For optical GBICs) Insert plugs into the SC connectors on the GBIC to prevent laser emissions.
Step 3 Hold down the clips on the side of the GBIC and remove the GBIC from the network module.
Step 4 Replace the GBIC with a similar model, or continue with network module removal.
Tip Gigabit Ethernet network modules can be removed with the GBIC installed.
