TOD_BAT

The battery for the time-of-day battery is low or failing.

Use the table below to determine which FRU to replace and how to replace it.

For B1xx SRCs:

To determine which Time-of-day (TOD) battery to replace on a model 570, 590, or 595, use the last byte in word 3 of the primary SRC.

If the last byte is a 10, then replace the TOD battery on the primary unit, service processor for model 570 or service processor 0 for model 590 or 595.
If the last byte is a 20, then replace the TOD battery on the secondary unit 1, service processor for model 570 or service processor 1 for model 590 or 595.
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, then replace the TOD battery on the primary unit service processor for model 570 or the TOD battery on service processor 0 for model 590 or 595.
- If the first byte is a 51, then replace the TOD battery on the secondary unit 1 service processor for model 570 or the TOD battery on service processor 1 for model 590 or 595.
If you have access to an 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, then replace the TOD battery on the primary unit service processor for model 570 or the TOD battery on service processor 0 for model 590 or 595.
- If the first byte of the hexadecimal value is a 51, then replace the TOD battery on the secondary unit 1 service processor for model 570 or the TOD battery on service processor 1 for model 590 or 595.

System model	Name of symbolic FRU to locate	FRU name	Link to locations information
505	TOD_BAT	Time-of-day (TOD) battery	Locations — model 505
510 and OpenPower® 710	TOD_BAT	Time-of-day (TOD) battery	Locations — model 510 and OpenPower 710
520	TOD_BAT	Time-of-day (TOD) battery	Locations — Model 520
550 and OpenPower 720	TOD_BAT	Time-of-day (TOD) battery	Locations — OpenPower 720 and Model 550
570	TOD_BAT	Primary unit, Time-of-day (TOD) batterySecondary unit 1, Time-of-day (TOD) battery	Locations — Model 570
575	TOD_BAT	Time-of-day (TOD) battery	Locations — model 575
590 and 595	TOD_BAT	Service processor card 0Service processor card 1	Locations — model 590 and 595

This ends the procedure.
