Online Insertion and Removal of Cisco Network Modules Procedure
Online Insertion and Removal of Cisco Network Modules
Procedure
Some Cisco routers allow you to replace network modules without switching off the router or affecting
the operation of other interfaces. This feature is called online insertion and removal (OIR). OIR of a
module provides uninterrupted operation to network users, maintains routing information, and ensures
session preservation.
Unlike other network modules, WAAS enhanced network modules use hard disks. Online removal of

disks without proper shutdown can result in file system corruption and might render the disk
unusable. The operating system on the network module must be shut down in an orderly way before
removing or powering down the module.
Cisco routers support OIR with similar modules only. If you remove a module, install another module

exactly like it in its place. If you remove a 2-slot module (along with any installed WAN or voice
interface cards), install another module and card combination exactly like it.
For a description of informational and error messages that may appear on the console during this
procedure, see the hardware installation guide for your router.
To perform online removal of a network module and insertion of a replacement, follow these steps, with
the router in privileged EXEC mode:
Step 1 Initiate a network module session using the following command:
Router# service-module integrated-service-engine slot / unit session
Trying 10.10.10.1, 2065 ... Open
Press RETURN to get started!
Router> enable
Router#
Step 2 Save the running configuration of the network module using the following command from the
Router # prompt:
Router# copy running-config tftp tftp-server-address filename
Step 3 Exit the network module session by pressing Control-Shift-6, followed by x.
On the router, clear the integrated-service-engine console session using the following command:
Step 4
Router# service-module integrated-service-engine slot / unit session clear
Perform a graceful shutdown of the network module disk drive by using the following command:
Step 5
Router# service-module integrated-service-engine slot / unit shutdown
Shut down the network module interface:
Step 6
Router (config)# interface integrated-service-engine slot/unit
Router (config-if)# shutdown
Router (config-if)# exit
