Connecting Cisco Unified Messaging Gateway Enhanced Network Modules to the Network
Revised: May 1, 2008, OL-16671-01
This guide describes how to connect Cisco Unified Messaging Gateway enhanced network modules to your network. It contains the following sections:
Cisco Unified Messaging Gateway Enhanced Network Modules
The Cisco Unified Messaging Gateway enhanced network module provides centralized management for larger Cisco Unity Express voicemail networks. The Cisco Unified Messaging Gateway enhanced network module:
•Intelligently routes voicemail messages
•Exchanges subscriber and directory information among the voicemail systems
•Provides interoperability with third party voicemail vendors within a voice messaging network
There are two versions of the Cisco Unified Messaging Gateway enhanced network module:
•NME-UMG supports up to 250 nodes.
•NME-UMG-EC supports up to 1000 nodes.
Note Cisco recommends attaching an uninterruptible power supply (UPS) to the router that houses the Cisco Unified Messaging Gateway enhanced network module. The UPS should include a signaling mechanism that directs the router to shut down the Cisco Unified Messaging Gateway application properly and then powers off the router.
Cisco IOS Release 12.3(4)T and later supports automatic switchover to the UPS device.
Note The Gigabit Ethernet port and compact flash (CF) slot, though available on the hardware, are not supported by the Cisco Unified Messaging Gateway enhanced network module. The CF slot has a metal cover.

Shutting Down Cisco Unified Messaging Gateway Enhanced Network Modules
Press the SHUTDOWN button on the network module faceplate for less than 2 seconds to perform a graceful shutdown of the network module before removing power from the router or before starting an online insertion and removal (OIR) sequence on the router. The application may take up to 2 minutes to fully shut down.
Caution If you press the SHUTDOWN button for more than 4 seconds, a nongraceful shutdown of the hard disk will occur and may corrupt files on the network module's hard disk. After a nongraceful shutdown, the HD and SYS LEDs remain lit. Press the SHUTDOWN button for less than 2 seconds to gracefully reboot the network module.
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.
Caution Unlike other network modules, Cisco Unified Messaging Gateway enhanced network modules use hard disks. Online removal of network modules without proper shutdown can cause file system corruption and might render the disk unusable. You must shut down the operating system on the network module in an orderly way before removing or powering down the module.
Caution Cisco routers support OIR with identical modules only. If you remove a module, install in its place another module exactly like the one you removed. 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 descriptions 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 by using the following command:
Router# service-module integrated-Service-Engine slot/unit session
Trying 10.10.10.1, 2065 ... OpenSE-Module> enableSE-Module#
Step 2 Save the running configuration of the network module by using the following command from the
SE-Module# prompt:SE-Module# copy running-config tftp:Address or name or remote host? tftp-server-addressDestination filename? filename
Note Depending on the specific TFTP server you are using, you might need to create a file with the same name on the TFTP server and verify that the file has the correct permissions before transferring the running configuration to the TFTP server.
Step 3 Exit the network module session by pressing Control-Shift-6, followed by pressing x.
Step 4 On the router, clear the integrated-Service-Engine console session by using the following command:
Router# service-module integrated-Service-Engine slot/unit session clear
Step 5 Perform a graceful shutdown of the network module disk drive by using the following command:Router# service-module integrated-Service-Engine slot/unit shutdown
Step 6 Shut down the network module interface:Router (config)# interface integrated-Service-Engine slot/unitRouter (config-if)# shutdownRouter (config-if)# exit
Step 7 Loosen the two captive screws that are holding the network module in the chassis slot.
Step 8 Slide the network module out of the slot.
Step 9 Align the replacement network module with the guides in the chassis slot, and slide it gently into the slot.
Note If the router is not fully configured with network modules, make sure that blank panels fill the unoccupied chassis slots to provide proper airflow.
Step 10 Push the module into place until you feel its edge connector mate securely with the connector on the backplane.
Step 11 Check that the network module LEDs are on. This inspection ensures that connections are secure and that the new unit is operational.
Step 12 Initiate a network module session by using the following command:Router# service-module integrated-Service-Engine slot/unit sessionTrying 10.10.10.1, 2129 ... OpenSE-Module> enableSE-Module#
Step 13 Restore the network module running configuration by using the following command from the service module prompt:SE-Module# copy tftp: running-configAddress or name or remote host? tftp-server-addressSource filename? filename
Step 14 Exit the network module session by pressing Control-Shift-6, followed by pressing x.
Step 15 On the router, clear the network module session by using the following command:
Router# service-module integrated-Service-Engine slot/unit session clear
