When you turn on the server, it performs a series of tests to check the operation of

information.
These charts list problem symptoms, along with suggested steps to correct the
problems. See the "Error symptoms" on page 68 for more information.
You can create a customized support page that is specific to your hardware,
complete with Frequently Asked Questions, Parts Information, Technical Hints
