1. Choose from the following options:
v If you are working from the Service Action Log, and a card position is listed with this failing item,
then that is where the error is located. Continue with the next step.
v Otherwise, record the bus number value, BBBB, in word 7 of the SRC, see "Breaking down the
SRC" on page 63 (in the Bus PIP Overview section) for help in determining the bus number. Search
for the bus number in HSM or the System Configuration Listing to determine which frame or I/O
tower contains the failing item. Record the frame or tower type. Then, continue with the next step.
2. Use the following table to determine which symbolic FRU to go to the system or tower you are working
on.
System frame or I/O Tower type containing the failing
item
Models 800 and 810
Model 825
Models 870 or 890 Base I/O Tower
FC 5074, FC 5078, FC 0578, FC 5079, or FC 5095

Using the type number of the storage IOA, go to Type, model, and part number list to determine the cache
battery pack part number.
To exchange the cache battery pack, see Type 2748, 2757, 2763, 2778, 2780, 2782, 5703, 5708 - Cache
