Catalyst 2970 Switch Hardware Installation Guide
3-2
If a switch fails POST, the System LED turns solid amber. The RPS LED is either
solid or blinking amber. The other LEDs are off.
POST failures are usually fatal. Call Cisco Systems if your switch does not pass
POST.
The LEDs on the front panel provide troubleshooting information about the
switch. They show POST failures, port-connectivity problems, and overall switch
performance. For a full description of the switch LEDs, see the
on page
1-6.
You can also get statistics from the browser interface, 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.
