Configuration Testing
and Troubleshooting
Troubleshooting is limited to two areas:
•
Hardware verification
Hardware tests are limited to the Power-On Self Test (POST), the system
diagnostics provided on the Customer Test diskette, and diagnostics for
additional boards that have been installed as part of the software
packages.
After your system has been assembled, it should be tested before being
put into service.
The same techniques are used for troubleshooting when you suspect
hardware problems.
•
Application operation problems
When the system does not operate as anticipated, there may be problems
in the administration of the application or in the administration of the
switch.
If the application problem is described in the troubleshooting tables, you
may be able to fix the problem by taking the action indicated.
Hardware Verification
Power-On Self Test
When the Power-On Self Test (POST) is initiated on booting the system,
two columns of information appear on the screen. The left column
identifies the item being tested; the right column indicates “PASS” or
“FAIL,” or the amount of memory allocated.
The following table shows the item being checked and indicates possible
causes for failure. If there is more than one cause listed, try to resolve the
problem starting with the first item listed.
