Action/
Possible Failing FRU
Replace the I/O planar specified by the location
code. The I/IO planar may be in the CEC or in
an external I/O drawer.
The problem is associated with bridge "y" in
I/O subsystem "x". Replace the I/O board
associated with x
x = I/O subsystem
1=0
2=1
3=2
4=3
5=4
6=5
See "Determining the Location Code" on page
243 or location code information related to this
error.
1. Replace the part identified by the location
code associated with this error code.
2. If the location code associated with this
error code identifies an adapter, and
replacing the adapter does not correct the
problem, replace the service processor/PCI
subsystem backplane.
Location: U0.1-P2
Go to "MAP 1542: I/O Problem Isolation" on
page 144.
1. Check the SPCN and RIO cabling going to
the I/O subsystem specified by the location
code.
2. Check for system firmware updates. Apply
any available updates.
3. Replace the I/O subsystem backplane
specified by the location code.
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 RTC 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, replace the service
processor/PCI backplane,
Location: U0.1-P2
1. Set time and date.
2. Refer to Action under error code 2803
0001.
Replace the service processor/PCI backplane,
