Hardware Troubleshooting

Your Cisco AS5800 was thoroughly tested before leaving the factory. If you encounter problems

initializing system startup, use the infor mation in this chapter to help isolate the cause.

This chapter contains the following sections:

•Problem Solving with Subsystems

•Identifying Startup Problems

•Troubleshooting the Power Subsystems

•Troubleshooting the Cooling Subsystems

•Troubleshooting the Processor Subsystems

•Troubleshooting Network Interfaces

The procedures in this chapter assume that you are troubleshooti ng the initial hardw are configura tion

and system startup. If you have removed or replaced components or changed any default settings,

the recommendations in this chapter might not apply. Review the safety warnings listed in the

publication Cisco AS5800 Universal Access Server Regulatory Compliance and Sa fety Information

before using the troubleshooting procedures in this chapter.

If you are unable to resolve the problem, contact a customer servic e represent ativ e for assista nce and

further instructions. Provide the representative with the following information:

•Date you received the system

•Chassis serial number

•Type of software and release number

•Brief description of the problem

•Brief explanation of the steps you have taken to isolate and resolve the problem

•Maintenance agreement or warranty information
