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.
You cannot fix hardware problems yourself, but identifying them may be
helpful so that the service personnel can bring appropriate materials.
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.
