3.3 Alarm Interface Panel Replacement

If the alarm interface panel (AIP) fails, a MAC Fail alarm displays on the CTC Alarms menu and/or the

LCD display on the fan tray will go blank.

Note A blown fuse on the AIP board can cause the LCD display to go blank.

To return a failed AIP, you must follow the standard Return Material Authorizations (RMA) procedures;

call (800) 553-NETS (6387) if you do not have an RMA number. Call Cisco Technical Assistance Center

(TAC) at 877-323-7368 for assistance in replacing the AIP and maintaining the original MAC address.

For more information on the AIP, see Chapter 1 in the Cisco ONS 15454 Installations and Operations

Guide.

Caution Do not perform this procedure on a node with live traffic. Hot-swapping the alarm interface panel

(AIP) can affect traffic and result in a loss of data. For assistance with AIP replacement contact Cisco

Technical Assistance Center (TAC) at 877-323-7368.
