The cache battery pack may be failing.

1. Use the cache battery pack location information in the service action log (SAL) if it is available. If the location is not available, use the address of the storage IOA, see System reference code (SRC) address formats, or see "System reference code (SRC) address formats" in the service guide for the system unit to find the location code for the storage IOA.

   Use the location code, see Locating FRUs, or see "Locating FRUs" in the service guide for the system unit to identify the storage IOA.

2. Using the type number of the storage IOA at the location you found, go to the Managing PCI Adapters document, order number SA76-0092 to determine the cache battery pack part number.
   Note: The 571F/575B combination storage and auxiliary cache IOA card set uses two card slot locations. The battery pack is located on the 575B side of the card set, regardless of the location found in the previous steps.

3. Replace the cache battery pack.
