The advanced diagnostic tests are intended to test only IBM products.
Non-IBM products, prototype cards, or modified options can give false
errors and invalid system responses.
IMPORTANT:
If more than one error code is displayed, diagnose the first error
code first. The cause of the first error code can cause false error
codes to be displayed.
If an adapter or device consists of more than one FRU, an error code
may be caused by any of the FRUs. Before replacing the adapter or
device, remove the FRUs, one by one, to see if the symptoms change.
