Cisco Unity Express Network Module Overview

This section provides information on the Cisco Unity Express network module (NM-CUE). (See Figure 1.)

---

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

---

---

Note The Fast Ethernet port and CompactFlash slot, though available on the hardware, are not supported by the Cisco Unity Express network module. The compact Flash slot has a metal cover.

---

Cisco Unity Express Network Module LEDs

All network modules have an enable (EN) LED. This LED indicates that the module has passed its self-tests and is available to the router.

All Cisco Unity Express network modules display an additional power (PWR) LED and a CompactFlash (CF) LED on the faceplate, and two additional LEDs for the Fast Ethernet port. (See Figure 2.)

---

Note The CF and Fast Ethernet port LEDs are not used by the Cisco Unity Express network module.

Figure 2 NM-CUE LEDs

LED	Meaning
ACT	There is activity on the Fast Ethernet connection. Note This LED is not used on the NM-CUE.
CF	The compact Flash module is active. Note This LED is not used on the NM-CUE.
DISK	There is activity on the 20-GB disk-expansion module hard drive.
EN	The module has passed self-test and is available to the router.
LINK	The Fast Ethernet connection is available to the network module. Note This LED is not used on the NM-CUE.
PWR	Power is available to the 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 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

Step 3 Exit the Cisco Unity Express network module console access session by pressing Ctrl-Shift-6, followed by x.

Step 4 On the router, clear the Cisco Unity Express network module console access session by using the following command:

Router# service-module service-engine slot/port session clear

Step 5 Perform a graceful halt of the Cisco Unity Express network module disk drive by using the following command:

Router# service-module service-engine slot/port shutdown 

Step 6 Loosen the two captive screws holding the Cisco Unity Express network module in the chassis slot.

Step 7 Slide the Cisco Unity Express network module out of the slot.

Step 8 Align the replacement Cisco Unity Express 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 9 Push the module into place until you feel its edge connector mate securely with the connector on the backplane.

Step 10 Tighten the two captive screws on the module faceplate.

Step 11 Check that the network module LEDs come on and that the power and enable LEDs on the front panel have also come on. This inspection ensures that connections are secure and that the new unit is operational.

Step 12 Initiate a Cisco Unity Express network module console access session with the following command:

Router# service-module service-engine slot/port session

Trying 10.10.10.1, 2129 ... Open

SE-netmodule con now available

Press RETURN to get started!

SE-netmodule> enable

SE-netmodule#

Step 13 Restore the Cisco Unity Express running configuration by using the following command from the SE-netmodule prompt:

SE-netmodule# copy ftp: running-config

Address or name or remote host? username/password/remote host

Source filename? filename

Step 14 Exit the Cisco Unity Express network module console access session by pressing Ctrl-Shift-6, followed by x.

Step 15 On the router, clear the console access session using the following command:

Router# service-module service-engine slot/port session clear
