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.

Solving Problems at the System Component Level

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:

System software boots successfully.
The supervisor engine and all switching modules are installed properly in their slots, and each was
initialized without problems.
Power supply—Includes the power supplies and power supply fans.
Fan assembly—The chassis fan assembly should operate whenever system power is on. You should
see the FAN LED turn green and hear the fan assembly operating. A red FAN LED indicates that
one or more fans in the fan assembly is not operating. You should immediately contact a customer
service representative if the fan assembly is not functioning properly. (See the
Customer Service" section on page
the fan assembly does not function properly at initial startup.
Supervisor engine—The supervisor engine contains the system operating software, so check your
supervisor engine if you have trouble with the system software. Status LEDs on the supervisor
engine indicate whether or not the supervisor engine is able to initialize the switching module.
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.
Switching modules—Status LEDs on each switching module indicate if the module has been
initialized by the supervisor engine. A switching module that is partially installed in the backplane
can cause the system to halt.
