Chapter 5 Troubleshooting The Installation - Cisco Router 7204 Installation And Configuration Manual

Troubleshooting the Installation
Your Cisco 7204 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:
Troubleshooting Overview, page 5-2
•
• Troubleshooting the Power Subsystem, page 5-5
Troubleshooting the Processor Subsystem, page 5-6
•
• Troubleshooting the Cooling Subsystem, page 5-7
The procedures in this chapter assume that you are troubleshooting the initial system startup, and that
the Cisco 7204 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 7204 before using the troubleshooting
procedures in this chapter.
