Lower Backplane Cover
Step 6
Grip the lower backplane cover and gently pull it away from the backplane.
Step 7
Unscrew the two screws that hold the AIP cover in place.
Step 8
Grip the cover and gently pull away from the backplane.
Note
On the 15454-SA-HD (P/N: 800-24848), 15454-SA-NEBS3E, 15454-SA-NEBS3, and
15454-SA-R1 (P/N: 800-07149) shelves, the AIP cover is clear plastic. On the 15454-SA-ANSI
shelf (P/N: 800-19857), the AIP cover is metal.
Step 9
Grip the AIP and gently pull it away from the backplane.
Step 10
Disconnect the fan-tray assembly power cable from the AIP.
Step 11
Set the old AIP aside for return to Cisco.
Caution
The type of shelf the AIP resides in determines the version of AIP that should replace the failed AIP. The
15454-SA-ANSI shelf (P/N: 800-19857) and 15454-SA-HD (P/N: 800-24848) currently use the 5A AIP,
(P/N: 73-7665-01). The 15454-SA-NEBS3E, 15454-SA-NEBS3, and 15454-SA-R1 (P/N: 800-07149)
shelves and earlier use the 2A AIP (P/N: 73-5262-01).
Caution
Do not put a 2A AIP (P/N: 73-5262-01) into a 15454-SA-ANSI shelf (P/N: 800-19857) or 15454-SA-HD
(P/N: 800-24848); doing so will cause a blown fuse on the AIP.
Step 12
Attach the fan-tray assembly power cable to the new AIP.
Step 13
Place the new AIP on the backplane by plugging the panel into the backplane using the DIN connector.
Step 14
Replace the AIP cover over the AIP and secure the cover with the two screws.
Step 15
Replace the lower backplane cover and secure the cover with the five screws.
