env <Return>
and step 3.
7. Run selftest by typing in
st <Return>
The tests take as much as 10 minutes, depending
on RAM size. They are complete when the
prompt returns. (The onboard selftest is a
valuable tool in isolating defects.)
8. The system may indicate that it has passed all the
selftests. Or, it may indicate a test that failed. If
neither happens, enter
de <Return>
Any errors should now be displayed. If there are
any errors, go to step VI. If there are no errors, go
to step V.
V. The debugger
is in system
mode and the
board auto
boots, or the
board has
passed selftests.
A. No problems.
Troubleshooting
is done.
No further troubleshooting steps are required.
Note
Even if the board passes all tests, it may
still be bad. Selftest does not try out all
functions in the board (for example,
SCSI, or VMEbus tests).
VI. The board
has failed one or
more of the tests
listed above, and
can not be
corrected using
the steps given.
A. There may be
some fault in
the board
hardware or the
on-board
debugging and
diagnostic
Þrmware.
1. Document the problem and return the board for
service.
2. Phone [phone].
