Diagnostic Error Codes
If an error is detected, the following appears:
Large X on the left side of the device icon.
Device ID (three digits)
Error code (two digits)
FRU code (four digits)
The device ID and error code indicate the detailed portion
of the FRU that caused the error. If replacing a FRU does
not correct the problem, see the device ID or error code
from the previous failure. If they have changed, the cause
might be because the new FRU is detective or the FRU
was incorrectly installed.
Device ID: If an error is detected by the diagnostic
tests, a three-digit device ID is displayed, indicating the
suspected device.
