• 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 5-1 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.
