The backup power module card might be failing.

Use the backup power module card 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 the System reference code format description to find the location code for the storage IOA.
Using the location code, see Part locations and location codes to identify the storage IOA.

Use Table 1 below to determine the service action. If more than one location code is listed in the table for the backup power module card, and the location of the backup power module card is not available in the SAL, continue with step 3 to identify the location.

Table 1. Backup power module card service information
Type and model	Part number	Description	Location code	Replacement procedure
5148-21L, 5148-22L, 8247-21L, 8247-22L, 8284-21A, or 8284-22A	Using the type number of the storage IOA at the location you found, see PCI adapter information by feature type to determine the part number.	Backup power module card for the PCIe3 x8 cache SAS RAID internal adapter Note: Replace the adapter and its associated backup power module card.	U`n`-P1-C14-C1	See PCIe3 cache SAS RAID internal adapter 6Gb for the 5148-21L, 5148-22L, 8247-21L, 8247-22L, 8284-21A, or 8284-22A.
5148-21L, 5148-22L, 8247-21L, 8247-22L, 8284-21A, or 8284-22A	Using the type number of the storage IOA at the location you found, see PCI adapter information by feature type to determine the part number.	Backup power module card for the PCIe3 x8 cache SAS RAID internal adapter Note: Replace the adapter and its associated backup power module card.	U`n`-P1-C15-C1	See PCIe3 cache SAS RAID internal adapter 6Gb for the 5148-21L, 5148-22L, 8247-21L, 8247-22L, 8284-21A, or 8284-22A.
8286-41A or 8286-42A	Using the type number of the storage IOA at the location you found, see PCI adapter information by feature type to determine the part number.	PCIe3 x8 cache SAS RAID internal adapter	U`n`-P1-C14	See PCIe3 cache SAS RAID internal adapter 6Gb for the 8286-41A or 8286-42A.
8286-41A or 8286-42A	Using the type number of the storage IOA at the location you found, see PCI adapter information by feature type to determine the part number.	PCIe3 x8 cache SAS RAID internal adapter	U`n`-P1-C15	See PCIe3 cache SAS RAID internal adapter 6Gb for the 8286-41A or 8286-42A.

To determine the location of the backup power module card, complete the following actions:

Record the resource name from the product activity log (PAL) or SAL entry for this error.
From the Start a Service Tool display, select Hardware service manager > Locate resource by resource name.
Enter the resource name of the storage IOA that you recorded from the PAL or SAL entry.
Select Display detail.
The PCI bus number is shown in decimal.
Use Table 2 to determine the location of the backup power module card. Then use Table 1 to determine the service action.

Table 2. Determining the backup power module card location
Type and model	PCI bus number (decimal)	Location code
5148-21L, 5148-22L, 8247-21L, 8247-22L, 8284-21A, or 8284-22A	21	U`n`-P1-C14-C1
5148-21L, 5148-22L, 8247-21L, 8247-22L, 8284-21A, or 8284-22A	31	U`n`-P1-C15-C1
8247-42L, 8286-41A, or 8286-42A	Not applicable	U`n`-P1-C14
8247-42L, 8286-41A, or 8286-42A	Not applicable	U`n`-P1-C15

This ends the procedure.
