Chapter 23 Connecting Cisco Unity Express Network Modules Online Insertion and Removal with a Cisco Unity Express Network Module 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. Caution Cisco Unity Express 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 Cisco Unity Express network module must be shut down in an orderly fashion before the network module is removed. Caution Cisco routers support hot-swapping with similar modules only. If you remove a network module, install 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 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 The Cisco Unity Express network module uses a blank password. Press Enter at the password prompt. Step 2 Step 3 Save the running configuration of the Cisco Unity Express network module using 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 Exit the Cisco Unity Express network module console access session by pressing Ctrl-Shift-6, followed by x.
