Troubleshooting the Installation

C H A P T E R 5

Your Cisco 7200 VXR 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 5-1

•Troubleshooting the Power Subsystem, page 5-6

•Troubleshooting the Processor Subsystem, page 5-7

•Troubleshooting the Cooling Subsystem, page 5-10

•Fiber-Optic Cleaning Information, page 5-10

The procedures in this chapter assume that you are troubleshooting the initial system startup, and that your router 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 7200 VXR router before using the troubleshooting procedures in this chapter.

Troubleshooting Overview

This section describes the troubleshooting methods used in this chapter and describes how the Cisco 7200 VXR routers are divided into subsystems for more efficient problem solving. 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

Table 5-1shows the general troubleshooting strategy described in this chapter. Refer to this table, as necessary, to follow the steps to isolate problems to a specific subsystem; resolve the problem if possible.
