A-5 Catalyst 6500 Series Switches Installation Guide OL-5781-08 Appendix A Troubleshooting 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.
A-6 Catalyst 6500 Series Switches Installation Guide OL-5781-08 Appendix A Troubleshooting 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. Table A-1 Environmental Monitoring for Supervisor Engine and Switching Modules ComponentAlarm Type LED Indication Action Supervisor engine temperature sensor exceeds major threshold 1 1. Temperature sensors monitor key supervisor engine components including daughter cards. Major STATUS2 LED red3 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. Syslog message and SNMP trap generated. If redundancy, system switches to redundant supervisor engine and the active supervisor engine shuts down. If there is no redundancy and the overtemperature condition is not corrected, the system shuts down after 5 minutes. Supervisor engine temperature sensor exceeds minor threshold Minor STATUS LED orange Syslog message and SNMP trap generated. Monitor the condition. Redundant supervisor engine temperature sensor exceeds major or minor threshold Major MinorSTATUS LED red STATUS LED orangeSyslog message and SNMP trap generated. If major alarm and the overtemperature condition is not corrected, the system shuts down after 5 minutes. If minor alarm, monitor the condition. Switching module temperature sensor exceeds major threshold Major STATUS LED red Syslog message and SNMP trap generated. Power down the module. Switching module temperature sensor exceeds minor threshold Minor STATUS LED orangeSyslog message and SNMP trap generated. Monitor the condition.
