TOD_BAT

Use the table below to find the service information for the specified FRU.

For B1xx SRCs:

To determine which Time-of-day (TOD) battery to replace on a 9406-MMA or 9117-MMA, use the last byte in word 3 of the primary SRC.

• If the last byte is a 10, replace the TOD battery on the primary unit, service processor for a 9406-MMA or 9117-MMA.
• If the last byte is a 20, replace the TOD battery on the secondary unit 1, service processor for a 9406-MMA or 9117-MMA.
• If the last byte is a 30, use one of the following methods to determine which TOD battery you need to replace:
  • If you have access to the Advanced System Management Interface (ASMI), log on and display the details of the service processor error log. Using the Platform Event Log id (shown in the first table of each detail of the log), look at the first byte.
  • • If the first byte is a 50, replace the TOD battery on the primary unit service processor for a 9406-MMA or 9117-MMA.
    • If the first byte is a 51, replace the TOD battery on the secondary unit 1 service processor for a 9406-MMA or 9117-MMA.
  • If you have access to a Hardware Management Console (HMC), log in as PE user and bring up Manage Serviceable Events under the Service Focal Point screen. Display the events for the corresponding service processor system, then double-click the system to see the details. Look at the Field Platform log ID, which contains a decimal value that you need to convert to a hexadecimal value.
  • • If the first byte of the hexadecimal value is a 50, replace the TOD battery on the primary unit service processor for a 9406-MMA or 9117-MMA.
    • If the first byte of the hexadecimal value is a 51, replace the TOD battery on the secondary unit 1 service processor for a 9406-MMA or 9117-MMA.

  Use the following table to determine the part number for the field replaceable unit (FRU).

  CCIN or FFC	Type and model	Part number	Description	Location code
  	8203-E4A, 8261-E4S, 9407-M15, 9408-M25	44V4359	System unit, Time-of-day (TOD) battery	Un-P1-E1
  	8204-E8A, 9409-M50	16G8095	system unit, Time-of-day (TOD) battery	Un-P1-E1
  	9406-MMA or 9117-MMA	16G8095	Primary unit, Time-of-day (TOD) battery	Un-P1-C11-E1
  	9406-MMA or 9117-MMA	16G8095	Secondary unit 1, Time-of-day (TOD) battery	Un-P1-C11-E1

  This ends the procedure.
