Troubleshooting Switching Modules
•
The output-fail LED on the power supplies are red and no power is delivered to the chassis. The
other LEDs on the power supply are green.
•
The Status LEDs on the switching modules and the supervisor engine are flashing green.
•
CPU Utilization LEDs are flashing green or off.
If you observe these conditions, contact the Cisco TAC for assistance in ordering replacement
redundancy modules and a clock.
Troubleshooting Switching Modules
Each switching module has one LED labeled STATUS that provides information about the module and
one numbered LED labeled LINK for each port on the module.
Figure 5-1
shows the Gigabit Ethernet
port and status LEDs.
Figure 5-2
shows the 10/100BASE-T port LEDs.
Table 5-1
describes the
switching module LEDs and their expected behavior.
