Possible Failing FRU
Errors reported against the real-time
clock can be caused by low battery
voltage and (more rarely) power
outages that occur during normal
system usage. These errors are
warnings that the real-time clock data
content needs to be re-established
and do not require any FRU
replacement unless the error is
persistent. When one of these errors
occurs, the time and date information
has been lost.
To set/restore the time and date, use
the operating system facility.
If the error is persistent:
1. Replace the battery.
2. Replace primary I/O backplane
Location: U0.1-P1
