The documentation set for this product strives to use bias-free language. For the purposes of this documentation set, bias-free is defined as language that does not imply discrimination based on age, disability, gender, racial identity, ethnic identity, sexual orientation, socioeconomic status, and intersectionality. Exceptions may be present in the documentation due to language that is hardcoded in the user interfaces of the product software, language used based on RFP documentation, or language that is used by a referenced third-party product.

Note The information in this chapter applies to all Catalyst 6500 series switches unless otherwise noted.
This chapter describes how to troubleshoot the Catalyst 6500 series switch hardware installation and contains these sections:
If your system has problems, use the information in this chapter to help isolate the cause. Problems with the initial startup are often caused by a switching module that has become dislodged from the backplane or a power supply that has been disconnected from the power cord connector. Although temperature conditions above the maximum acceptable level rarely occur at initial startup, you might encounter these conditions during extended operation. Long-term monitoring functions also include independent reporting of DC-output voltage problems.
Note This chapter covers only the chassis component hardware aspects of troubleshooting. For module-specific information, refer to the Catalyst 6500 Series Switch Module Installation Guide.
When the initial system startup is complete, verify the following:
If one or more of the above conditions are not met, use the procedures in this chapter to isolate and, if possible, resolve the problem. If all of the above conditions are met, and the hardware installation is complete, refer to these publications to troubleshoot the software: 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. Also, refer to your software release notes for hardware support information and software caveats.
The key to success when troubleshooting the system is to isolate the problem to a specific system component. The first step is to compare what the system is doing to what it should be doing. Because a startup problem can usually be attributed to a single component, it is more efficient to isolate the problem to a subsystem rather than troubleshoot each separate component in the system.
The switch consists of these subsystems:
If you have a redundant supervisor engine, refer to the Catalyst 6500 Series Switch Software Configuration Guide or the Catalyst 6500 Series Switch Cisco IOS Software Configuration Guide publications for descriptions of how the redundant supervisor engine comes online and how the software images are handled.
LEDs indicate all system states in the startup sequence. By checking the LEDs, you can determine when and where the system failed in the startup sequence.
To identify startup problems, follow these steps:
Step 1 Turn on the power supplies. You should immediately hear the system fan assembly begin to operate.
Step 2 Verify that the LEDs on the supervisor engine light as follows:
If any LEDs on the supervisor engine front panel are red or orange, see the “Troubleshooting Modules” section.
If you have a redundant supervisor engine, refer to the Catalyst 6500 Series Switch Software Configuration Guide or the Catalyst 6500 Series Switch Cisco IOS Software Configuration Guide publications for descriptions of how the redundant supervisor engine comes online and how the software images are handled.
For a complete description of the supervisor engine LEDs, refer to the Catalyst 6500 Series Switch Module Installation Guide.
Step 3 Verify that the STATUS LEDs on the supervisor engine and on each switching module are green when the supervisor engine completes initialization.
The STATUS LED indicates that the supervisor engine or switching modules are receiving power, have been recognized by the supervisor engine, and contain a valid flash code version. This LED does not indicate the state of the individual interfaces on the switching modules. If a STATUS LED is red or orange, see the “Troubleshooting Modules” section.
Step 4 If the startup information and system banner do not display at startup, refer to the Catalyst 6500 Series Switch Module Installation Guide to verify that the terminal is set correctly and that it is connected properly to the supervisor engine console port.
If the INPUT OK LED does not light after you turn on the power switch, follow these steps to isolate a power subsystem problem:
Step 1 Verify that the INPUT OK LED on the power supply is green.
If this unit has more than one power cord, repeat Verify that the INPUT OK LED on the power supply is green. for each power supply.
If the INPUT OK LED still fails to light when the switch is connected to a different power source with a new power cord, the power supply is probably faulty.
If a second power supply is available, install it in the second power supply bay, and contact a customer service representative for further instructions.
Step 2 If you have a second (redundant) power supply, repeat Verify that the INPUT OK LED on the power supply is green. for this power supply.
If you are unable to resolve the problem or if you determine that either a power supply or backplane connector is faulty, see the “Contacting Customer Service” section.
To isolate a fan assembly problem, follow these steps:
Step 1 Verify 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 to determine whether or not the power subsystem is functioning properly.
Step 2 Check 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.
To isolate a supervisor engine or switching module problem, follow these steps:
Step 1 Verify that all status LEDs are on.
Step 2 If 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.
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.
Table A-1 lists the environmental indicators for the supervisor engine and switching modules.
Note Refer to the Catalyst 6500 Series Switch Module Installation Guide for additional information on LEDs, including the supervisor engine SYSTEM LED.

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.
