Diagnosing Problems

The LEDs on the front panel 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, from the CLI, or from 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 2-5 for information on POST.

Note POST failures are usually fatal. Contact your Cisco technical support representative if your switch does

not pass POST.

Switch LEDs

If you have physical access to the switch, look at the port LEDs for troubleshooting information about

the switch. See the “LEDs” section on page 1-11 for a description of the LED colors and their meanings.
