1.7.3 Alarm Interface Panel

The AIP is located above the alarm contacts on the lower section of the backplane. The AIP provides

surge protection for the ONS 15454 ANSI. It also provides an interface from the backplane to the

fan-tray assembly and LCD. The AIP plugs into the backplane using a 96-pin DIN connector and is held

in place with two retaining screws. The panel has a nonvolatile memory chip that stores the unique node

address (MAC address). The MAC address identifies the nodes that support circuits. It allows

Cisco Transport Controller (CTC) to determine circuit sources, destinations, and spans. The

TCC2/TCC2P cards in the ONS 15454 ANSI also use the MAC address to store the node database.

The 5-A AIP (73-7665-XX) is required when installing fan-tray assembly 15454-FTA3 or

15454-CC-FTA, which comes preinstalled on the shelf assembly (15454-SA-ANSI or 15454-SA-HD).

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

1.7.4 Alarm Interface Panel Replacement

If the AIP fails, a MAC Fail alarm appears on the CTC Alarms menu and/or the LCD display on the

fan-tray assembly goes blank. To perform an in-service replacement of the AIP, you must contact the

Cisco Technical Assistance Center (Cisco TAC). For contact information, see the
