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.
