Troubleshooting the Installation
Your Cisco 7206 router went through extensive testing before leaving the factory. However, if you
encounter problems starting the router, use the information in this chapter to help isolate the cause of the
problems. This chapter contains the following sections:
• Contacting a Customer Service Representative, page 6-1
• Troubleshooting Overview, page 6-2
• Troubleshooting the Power Subsystem, page 6-5
• Troubleshooting the Processor Subsystem, page 6-6
• Troubleshooting the Cooling Subsystem, page 6-7
The procedures in this chapter assume that you are troubleshooting the initial system startup, and that
the Cisco 7206 is in the original factory configuration. If you have removed or replaced components or
changed any default settings, the recommendations in this chapter might not apply. Make sure to review
the safety warnings listed in the publication Regulatory Compliance and Safety Information for the
Cisco 7200 Series Routers that accompanied your Cisco 7206 before using the troubleshooting
procedures in this chapter.
Contacting a Customer Service Representative
If you are unable to easily solve the problem, contact a customer service representative for assistance
and further instructions. Provide the representative with the following information:
• Date you received the router
• Chassis serial number
• Type of software and release number
• Brief description of the problem you are having
• Brief explanation of the steps you have taken to isolate and resolve the problem
• Maintenance agreement or warranty information
Figure 6-1 shows the general troubleshooting strategy described in this chapter. Refer to this chart, as
necessary, to follow the steps to isolate problems to a specific subsystem; then resolve the problem if
possible.
