If a Catalyst 3750-X or 3560-X switch is attached to the XPS, you can troubleshoot it from Cisco Network Assistant or from the CLI. See the switch software configuration guide or the switch command reference guide on Cisco.com.

You can also access the Support and Documentation Website (http://www.cisco.com/en/US/support/index.html) for a list of known hardware problems and troubleshooting documentation.
