Troubleshooting
Note The information in this chapter applies to all Catalyst 6500 series switches (Catalyst 6503,
Catalyst 6503-E, Catalyst 6504-E, Catalyst 6506, Catalyst 6506-E, Catalyst 6509, Catalyst 6509-E,
Catalyst 6509-NEB, Catalyst 6509-NEB-A, and Catalyst 6513) unless otherwise noted.
This chapter describes how to troubleshoot the Catalyst 6500 series switch hardware installation and
contains these sections:
• Getting Started, page E-1
• Solving Problems at the System Component Level, page E-2
• Identifying Startup Problems, page E-3
• Troubleshooting the Power Supply, page E-4
• Troubleshooting the Fan Assembly, page E-5
• Troubleshooting Modules, page E-5
• Contacting Customer Service, page E-7
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.
Getting Started
When the initial system startup is complete, verify the following:
• Power supplies are supplying power to the system.
• The system fan assembly is operating.
