Action / Possible Failing FRU
If the location code shown on the
operator panel identifies a card slot:
1. Replace the adapter in the slot
identified.
2. Replace the I/O board (See note on
page 93.)
If the location code shown does not

(See note on page 93.)
"xx" indicates the PCI bus number with
the error
1. Attempt to reboot the system in
service mode; this preserves the
AIX error log. If the reboot is
successful, run diagnostics in
problem determination mode to
determine the cause of failure.
Otherwise continue.
2. Refer to the "Bus SRN to FRU
Reference Table" page 123, using
PCI Bus "xx" for isolation of the
failing device.
1. Errors reported against the real time
clock (RTC) can be caused by low
battery voltage and (more rarely)
power outages that occur during
normal system usage. These errors
are warnings that the RTC data
content had to be re-established
and do not require any FRU
replacement unless the error is
persistent. When one of these
errors occurs, the power-on
password and time and date
information has been lost.
v To set/restore a power-on
password, use the SMS utility.
v To set/restore the time and date,
use the operating system facility.
2. If the error is persistent, replace the
battery.
3. If the error is persistent after battery
replacement, replace the I/O board.
(See note on page 93.)
