Cisco Systems 4500 manual Troubleshooting Switching Modules, Gigabit Ethernet Port and Status LEDs

Chapter 5 Troubleshooting

Troubleshooting Switching Modules

•The switch powers down and stays down for a few minutes to a few days for no clear reason.

•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 5-1shows the Gigabit Ethernet port and status LEDs. Figure 5-2shows the 10/100BASE-T port LEDs. Table 5-1describes the switching module LEDs and their expected behavior.
