  Troubleshooting the Fan Assembly
Troubleshooting the Fan Assembly
To isolate a fan assembly problem, follow these steps:
Step 1Verify that the FAN LED on the fan assembly is green.
If the FAN LED is not green, see the “Solving Problems at the System Component Level” section on 
page A-2 to determine whether or not the power subsystem is functioning properly.
Step 2Check to determine if the FAN LED is red. If the FAN LED is red, the fan assembly is not seated in the 
backplane or has malfunctioned. 
Do the following:
To ensure that the fan assembly is seated properly, loosen the captive installation screws, remove the 
fan assembly, and reinstall it.
Tighten all captive installation screws, and then restart the system.
If the FAN LED is still red, the system detects an individual fan failure. Contact a customer service 
representative for instructions.
Troubleshooting Modules
To isolate a supervisor engine or switching module problem, follow these steps:
Step 1Verify that all status LEDs are on.
Step 2If any status LEDs on the supervisor engine or any switching modules are red or off, the module might 
have shifted out of its slot. Reseat the module until both ejector levers are at right angles to the rear of 
the chassis. Tighten the captive installation screws at the left and right of the module front panel, and 
restart the system.
STATUS LED Indications
The STATUS LEDs can indicate two alarm types: major and minor. Major alarms indicate a critical 
problem that could lead to the system being shut down. Minor alarms are for informational purposes 
only, giving you notice of a problem that could turn critical if corrective action is not taken. 
When the system has an alarm (major or minor) that indicates an overtemperature condition, the alarm 
is not canceled and no action is taken (such as a module reset or a shutdown) for 5 minutes. If the 
temperature falls 5°C (41°F) below the alarm threshold during this period, the alarm is canceled. 
Ta b l e A - 1 lists the environmental indicators for the supervisor engine and switching modules.
NoteRefer to the Catalyst 6500 Series Switch Module Installation Guide for additional information on LEDs, 
including the supervisor engine SYSTEM LED.

  Troubleshooting Modules
Refer to the Catalyst 6500 Series Switch Software Configuration Guide, the Catalyst 6500 Series Switch 
Cisco IOS Software Configuration Guide, the Catalyst 6500 Series Switch Command Reference, or the 
Catalyst 6500 Series Switch Cisco IOS Command Reference publications to configure or enable the 
interfaces. After the system reinitializes the interfaces, the status LED on the module should be green.
If you still experience trouble with the startup, see the “Contacting Customer Service” section on 
page A-7.

2. A STATUS LED is located on the supervisor engine front panel and all module front panels.
3. The STATUS LED is red on the failed supervisor engine. If there is no redundant supervisor, the SYSTEM LED is red also.

shuts down.
If there is no redundancy and the overtemperature 
condition is not corrected, the system shuts down 
after 5 minutes.
