Checking the Installation

• 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

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