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 Device Manager,
from the CLI, or from an SNMP workstation.
Switch POST Results
POST failures are usually fatal. Contact your Cisco technical support representative if your switch does
not pass POST.
Note
Switch LEDs
If you have physical access to the switch, look at the port LEDs for troubleshooting information about the
switch. See the LED section for a description of the LED colors and their meanings.
