System Board and CPU Card Checkout
The processing functions are performed by both the
system board and the CPU card.
Processor problems can
be caused by either FRU.
However, the CPU card
generally has a lower probability of failure.
If a numeric
code indicates the system board or the CPU card as a
failing FRU, or the CPU card is indicated by a diagnostic
test by showing FRU code 11, use the following procedure
to isolate the problem:
1.
Run the system board test to verify the symptom.
This test verifies both the system board and the CPU
card.
If no error is detected, return to “Checkout
Guide” on page
