How to Use Error Messages
Use the error codes displayed on the screen to diagnose
failures. If more than one error code is displayed, begin
the diagnosis with the first error code. Whatever caused
the first error code can result in false error codes being
displayed. If no error code is displayed, see if the error
symptom is listed in the “Symptom-to FRU Index” section.
How to Diagnose Multiple FRUs
When the adapter or device has more than one FRU, the
error code could be caused by any of them. Before
replacing multiple FRUs, try removing or exchanging each
FRU, one by one in the designated sequence, to see if the
symptoms change.
Reset Switch

microcode status) and forces the power off. Use this push
button to power off when power is not completely off or the
microcode is in a hung state. See the “Locations” section
of each model for Reset switch location.
