Chapter 23 Connecting Cisco Unity Express Network Modules
Online Insertion and Removal with a Cisco Unity Express
Network Module
Some Cisco modular access routers allow you to replace network modules without switching off the
router or affecting the operation of other interfaces. This feature is often called hot-swapping or online
insertion and removal (OIR). Hot-swapping of network modules provides uninterrupted operation to
network users, maintains routing information, and ensures session preservation.
Cisco Unity Express network modules use hard disks. Online removal of disks without proper shutdown
Caution
can result in file system corruption and might render the disk unusable. The operating system on the
Cisco Unity Express network module must be shut down in an orderly fashion before the network
module is removed.
Cisco routers support hot-swapping with similar modules only. If you remove a network module, install
Caution
another module exactly like it in its place.
For a description of informational and error messages that may appear on the console during this
procedure, see the hardware installation guide for your type of router.
To perform online removal of a Cisco Unity Express network module and insertion of a replacement,
follow these steps with the router in privileged EXEC mode:
Step 1 Initiate a Cisco Unity Express network module console access session using the following command:
Router# service-module service-engine slot / port session
