Error Code Description Action / Possible Failing FRU
40200053 An inlet memory temperature condition
detected. (Critically high temperature
sensed at the air flow inlet.)
1. Check system unit fans.
Locations: F1, F2, F3, F4
2. Replace the system board.
Location: P1
(See note 3 on page 109.)
40210011 A slow fan detected. Check:

was exceeded (System firmware
surveillance time-out).
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
40A0 0000. If a location code
appears with the error code or
checkpoint, replace the part at that
location.
3. If the problem is not resolved, call
service support.
40B00000 The operating system surveillance
interval exceeded (operating system
surveillance time-out).
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. Call service support.
40D00003 An unknown slow shutdown commanded. Insure the ambient temperature is in
the proper range.
40D00004 An unknown fast shutdown occurred. Insure the ambient temperature is in
the proper range.
40D00101 BIST on the system board failed. Replace the system board. (See note
3 on page 109.)
40D00102 BIST on the system board failed. Replace system board.
