UPSUNIT

The uninterruptible power supply (UPS) might be the failing component.

Complete the following steps:

1. Is the problem that the system has a UPS reference code, but the UPS does not have a fault code?
   • Yes: Continue with the next step.
   • No: Go to step 3.
2. Remove the UPS signal cable from the system connector. Does the system report a UPS reference code now?
   • No: Continue with the next step.
   • Yes: Replace the following, one at a time, until the problem is resolved. Use the following table to determine the part number for the field replaceable unit (FRU).

     CCIN or FCC	Type and model	Part number	Description	Location code
     	8202-E4B, 8202-E4C, 8202-E4D, 8205-E6B, 8205-E6C, 8205-E6D, 8231-E2B, 8231-E1C, 8231-E1D, 8231-E2C, 8231-E2D, 8233-E8B, 8236-E8C, 8268-E1D	See System parts.	System backplane	Un-P1
     	8248-L4T, 8408-E8D, 8412-EAD, 9109-RMD, 9117-MMB, 9117-MMC, 9117-MMD, 9179-MHB, 9179-MHC, 9179-MHD	See System parts.	Service processor card (SPCN function for the system unit)	Un-P1-C1
     	UPS		Remote power controller (RPC)

     If you need additional information for failing part numbers, location codes, or removal and replacement procedures, see Part locations and location codes. Select your machine type and model number to find additional location codes, part numbers, or replacement procedures for your system.

     This ends the procedure.
3. Complete the following steps:
   1. Verify the UPS signal cable, between the UPS and the system, is connected and seated properly.
   2. Have the customer call the UPS provider for service if a problem is found.
   3. Call service support if the problem is not resolved after the UPS is verified as working correctly.

This ends the procedure.
