6. You may need to use the cnfg command (see 

Appendix A) to change clock speed and/or 
Ethernet Address, and then later return to
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.

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 1-800-222-5640.
