Connecting Cisco Unity Express Enhanced Network Modules

This chapter describes Cisco Unity Express enhanced network modules for Cisco integrated services routers, and contains the following sections:

Tip

To determine whether your Cisco router supports a specific network module, see Table 1-6 on page 1-16.

Cisco Unity Express Enhanced Network Modules

The Cisco Unity Express enhanced network module (NME-CUE) provides 24 ports that store a maximum of 250 voice mailboxes and 300 hours of voice messages. (See Figure 24-1.)

Caution

To comply with the Telcordia GR-1089 NEBS standard for electromagnetic compatibility and safety, connect the Cisco Unity Express enhanced network module (NME-CUE) only to intrabuilding or nonexposed wiring or cabling. The intrabuilding cable must be shielded, and the shield must be grounded at both ends

The NME-CUE ships from the factory with the following hardware preinstalled. (See Table 24-1.)

Table 24-1 Preinstalled Hardware in Cisco Unity Express Enhanced Network Modules
Model	Hard Disk	Memory
NME-CUE	80 GB (SATA)	512 MB

Note The Gigabit Ethernet port and compact flash (CF) slot, though available on the hardware, are not supported by the Cisco Unity Express enhanced network module. The CF slot has a metal cover.


SHUTDOWN	Press the SHUTDOWN button for less than 2 seconds to gracefully shut down the module. Press the SHUTDOWN button for more than 4 seconds to cause an immediate module shutdown, which may impact file operations that are in progress.
DISK	Status of hard drive activity: On—Active. Off—Inactive.
SYS	Status of system shutdown: Note Do not remove power without first shutting down the application. On—Application is stable. Off—System is shut down and ready for host power down. Flashing—System shutdown is in progress.
EN	Status of the network module: On—Detected by the host Cisco IOS software and enabled. Off—Disabled.

Shutting Down Cisco Unity Express 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 Unity Express Enhanced Network Modules

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 Unity Express enhanced network modules use hard disks. Online removal of disks 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 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.

Caution

If you need to preserve the data on the Cisco Unity Express enhanced network module, or need to transfer the data to a new Cisco Unity Express enhanced network module, perform a backup of the data before removing the module, and restore the data after installing the new module. For more information about backing up and restoring data, see the "Backup and Restore" chapter in the Cisco Unity Express 3.0 Voice-Mail and Auto-Attendant CLI Administrator Guide:

To perform online removal of a network module and insertion of a replacement, follow these steps, with the router in privileged EXEC mode:

Step 2

Save the running configuration of the network module by using the following command from the
SE-Module# prompt:

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:

Step 8

Loosen the two captive screws that are holding the network module in the chassis slot.

Step 10

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 11

Push the module into place until you feel its edge connector mate securely with the connector on the backplane.

Step 12

Reconnect the network interface cables previously removed in Step 7.

Step 13

Check that the network module LEDs are on and that the power (PWR) and enable (EN) LEDs on the front panel are also on. This inspection ensures that connections are secure and that the new unit is operational.

Step 15

Restore the network module running configuration by using the following command from the service module prompt:

Step 16

Exit the network module session by pressing Control-Shift-6, followed by pressing x.

Step 17

On the router, clear the network module session by using the following command:

Router# service-module integrated-service-engine slot/unit session clear
