Table 9. Common Firmware Error Codes (continued)
Error Code Description
B1xx 4672 Critical temperature in I/O subsystem
B1xx 4681 JTAG scan interface
B1xx 4682 Problem with system VPD on operator panel.
B1xx 4690 Description: Operating system surveillance time out (AIX to service processor interface failure).
Action:
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, another error that points to the cause of the operating system
crash. Use the other error as the starting point for your service action.
If the system will not boot to AIX, power off and look at the service processor error log. Look for
error codes (with time stamps that correspond to the boot that was just attempted) that indicate
hardware failures. If these error codes are found, record them, find the error code listed in the
Chapter 5, "Error Code to FRU Index," on page 131, and perform the indicated actions.
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:
a. Look at the AIX error log entry containing B1xx4690. This will be a "SCAN_ERROR_CHRP"
b. In the detail data, find the string "B1xx4690" (If present, it will be at byte 60 of the detail
c.
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.
B1xx 4691 Description: System firmware to service processor interface failure. (System firmware surveillance
time out)
Action:
1. Check for system firmware updates.
2. Go to the service processor main menu and select System Information Menu. Then select
Read Progress Indicators From Last System Boot. Begin your repair action with the error
code or checkpoint immediately preceding B1xx 4691. If a location code displays with the error
code or checkpoint, replace the part at that location.
3. If the problem is not resolved, call service support.

1. Check ambient temperature.
2. Check air supply to fans.
3. Check fans for proper installation and
operation.
4. Check for unsupported cards (which may be
too hot)

1. Replace the operator panel, location:
U0.1-L1. Do not swap the old VPD module
onto the new operator panel. Call service
