Diagnosing Problems

The switch LEDs provide troubleshooting information about the switch. They show POST failures, port-connectivity problems, and overall switch performance. You can also get statistics from the device manager, the CLI, or an SNMP workstation. See the software configuration guide, the switch command reference guide on Cisco.com, or the documentation that came with your SNMP application for details.

Switch POST Results

See the “Verifying Switch Operation” section on page 2-5for information on POST.

Note POST failures are usually fatal. Contact your Cisco technical support representative if your switch does not pass POST.
