Service Guide
Description
I/O cooling
JTAG Scan Interface
Operating system surveillance time
out (AIX to service processor
interface failure)
Action/ Possible Failing FRU
1. Check ambient temperature
2. Check air supply to fans
3. Check fans for proper installation
and operation
4. Check for unsupported cards
(that may be too hot)
5. Operator panel, Location: L1
1. Processor card, Location: P1-C1
2. System board, Location: P1 (See
note 3 on page 41.)
1. This error code indicates that the
operating system terminated early
(which usually implies an
operating system crash). This
error code may appear in the
service processor error log by
itself. However, in the AIX error
log, there should be another error
which points to the cause of the
operating system crash. Use the
other error as the starting point
for your service action.
2. The other possibility is that the
operating system was not found
during a prior boot attempt. To
determine if this occurred, do the
following: Look at the AIX error
log entry containing B1xx4690.
This will be a
"SCAN_ERROR_CHRP" error
with an identifier of BFEC0425. In
the detail data, find the string
"B1xx4690" (If present, it will be
at byte 60 of the detail data.)
Then go forward 8 bytes after the
"B1" to byte 68 and look at bytes
68 and 69. If the values of bytes
68 and 69 are A2B0, this
indicates that the firmware was
unable to find a bootable device
in the boot list that is set in the
SMS menus. If the system is up,
the boot list problem has been
corrected and the B1xx 4690 can
be treated as an informational
message with no actions
required.
3. Call service support.
