This chapter describes the LEDs used to confirm and troubleshoot operation of the route processor, switch processors, and interface modules and includes the following sections:

• Confirming the Installation

• Troubleshooting Interface Modules

• Component Troubleshooting Flowchart

• Route Processor and Switch Processor LEDs

• Interface Module LEDs

Confirming the Installation

Problems with the initial startup are often caused by an interface module or power supply that has become dislodged from the backplane or chassis power connector. Although over-temperature conditions rarely occur at initial startup, the environmental monitoring functions are included because they also monitor DC line voltages. At the initial system boot, verify the following:

•The power supplies are installed properly and are supplying power to the system.

•The system fan assembly is operating.

•The system software boots successfully.

•The route processor, switch processors, and interface modules are properly installed in their slots, and each is initialized without problems.

When these conditions are met, the hardware installation is complete. If the startup sequence fails before these conditions are met, use the procedures in this chapter to isolate and, if possible, resolve the problem.

If you are unable to solve a problem, contact a customer service representative for assistance and further instructions. Before you call, gather the following information:

•Date you received the components

•Component serial number (see label on the front of the component)

•Type of software and release number

•Brief description of the problem

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

•Maintenance agreement or warranty information

Troubleshooting Interface Modules

Your interface module went through extensive testing and burn-in before leaving the factory; however, if your system appears to have problems starting up, use the information in this chapter to help isolate the cause.

When you have completed the troubleshooting procedures in this chapter, continue with the following interface module troubleshooting steps:

•Read the "Connecting Interface Modules to a Network" section on page 2-10.

•Use the commands listed in the Layer 3 Switching Software Feature and Configuration Guide to test the interface connection.

Component Troubleshooting Flowchart

The flowchart in Figure 4-1 helps you determine which component might
have malfunctioned.
