Troubleshooting Overview
At the initial system boot, you should verify the following:
•
External power cables are connected, and the proper source power is being supplied.
•
The system fan or blower is operating.
•
The system software boots successfully.
•
The RSP and all interface processors are properly installed in their slots, and each initializes (is
enabled by the system software) without problems.
Note
If after initialization your system indicates that particular interfaces cannot be found, or that your
interface processor is not recognized, verify that your loaded and running Cisco IOS software is
compatible with the Cisco 7500 series router in which your interface processor is installed. To do this,
first determine the Cisco 7500 series router you have, and then refer to the appropriate specification
tables in
Chapter 1, “Cisco 7500 Series Product Overview.”
If you determine that your loaded and running Cisco IOS software is not compatible with your Cisco
7500 series router, or you suspect it might not be compatible with your interface processor, see the
“Preface” chapter for instructions on how to obtain technical assistance.
When each of these conditions is met, the hardware installation is complete, and you should proceed to
Chapter 4, “Performing a Basic Configuration of the System,”
to perform a basic system configuration.
You should also refer to the appropriate companion software-configuration documentation to fully
configure the Cisco IOS software, protocols, and individual interfaces in your system. 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 easily solve the problem, contact a customer service representative for assistance
and further instructions. Before you call, have the following information ready to help your service
provider assist you as quickly as possible:
•
Date you received the router and the chassis serial number (located on a label on the right rear deck
of the chassis)
•
Interface processor configuration (which interface processors you have installed)
•
Type of Cisco IOS software running and its release number
•
Brief description of the problem you are having and the steps you have already taken to isolate and
resolve the problem
•
Maintenance agreement or warranty information
