13.7.3 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 5-A AIP (73-7665-XX) is required when installing the new fan-tray assembly (15454-FTA3), which
Note
comes preinstalled on the shelf assembly (15454-SA-ANSI or 15454-SA-HD).
The MAC address identifies the nodes that support circuits. It allows Cisco Transport Controller (CTC)
Note
to determine circuit sources, destinations, and spans. The TCC2 cards in the ONS 15454 ANSI also use
the MAC address to store the node database.
A blown fuse on the AIP board can cause the LCD display to go blank.
