Diagnostic Error Codes
A detected error is shown as in the following example:
Large X on the left side of the device icon.
Device ID (three digit)
Error code (two digit)
FRU code (four digit)
The device ID and error code are used to indicate the
detail 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 that the FRU was incorrectly installed.
Device ID: If an error is detected by the diagnostic
tests, a three-digits device ID is displayed. The device ID
indicates suspected device.
