Chapter 4 Troubleshooting

Getting Started

Note This chapter covers only the chassis component hardware aspects of troubleshooting. For module-specific information, refer to the Cisco 7600 Series Internet Router Module Installation Guide.

Getting Started

When the initial system boot is complete, verify the following:

Power supplies are supplying power to the system.

The system fan assembly is operating.

System software boots successfully.

The supervisor engine and all switching modules are installed properly in their slots, and each was initialized without problems.

If each of these conditions is met and the hardware installation is complete, refer to the Cisco 7600 Series Internet Router Software Configuration Guide, the Cisco 7600 Series Internet Router IOS Software Configuration Guide, the Cisco 7600 Series Internet Router Command Reference, or the Cisco 7600 Series Internet Router IOS Command Reference publications to troubleshoot the software. However, if any of these conditions are not met, use the procedures in this chapter to isolate and, if possible, resolve the problem.

Problem Solving to the System Component Level

The key to success when troubleshooting the system is to isolate the problem to a specific system component. The first step is to compare what the system is doing to what it should be doing. Because a startup problem can usually be attributed to a single component, it is more efficient to isolate the problem to a subsystem rather than troubleshoot each separate component in the system.

The switch consists of the following subsystems:

Power supply—Includes the power supplies and power supply fans.

Fan assembly—The chassis fan assembly should operate whenever system power is on. You should see the FAN LED turn green and should be able to hear the fan assembly to determine whether or not it is operating. If the FAN
