Troubleshooting
The LEDs on the front panel provide troubleshooting information about the
switch. They show failures in the power-on self-test (POST), port-connectivity
problems, and overall switch performance. For a full description of the switch
LEDs, see the “LEDs” section on page 2-13.
You can also get statistics from the browser interface, from the command-line
interface (CLI), or from a Simple Network Management Protocol (SNMP)
workstation. Refer to the software configuration guide, the switch command
reference guide on Cisco.com, or the documentation that came with your SNMP
application for details.
This chapter describes these topics for troubleshooting problems:
• Understanding POST Results, page 4-1
• Clearing the Switch IP Address and Configuration, page 4-2
• Replacing a Failed Stack Member, page 4-9
Understanding POST Results
As the switch powers on, it begins the power-on self-test (POST), a series of tests
that runs automatically to ensure that the switch functions properly. POST lasts
approximately 1 minute.
