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. Ta ble 5-1 describes the
switching module LEDs and their expected behavior.
