Troubleshooting
Note This document describes the Cisco 7609 Internet Router (OSR-7609) and not
the Cisco 7609 Internet Router (CISCO7609).
This chapter describes how to troubleshoot the Cisco 7609 Internet Router
(OSR-7609) hardware installation and contains these sections:
•Getting Started, page4-2
•Problem Solving to the System Component Level, page 4-2
•Identifying Startup Problems, page 4-3
•Troubleshooting the Power Supply, page 4-5
•Troubleshooting the Fan Assembly, page4-6
•Troubleshooting Modules, page 4-6
•Contacting Customer Service, page 4-7
If your system has problems starting up, use the information in this chapter to help
isolate the cause. Problems with the initial startup are often caused by a switching
module that has become dislodged from the backplane or a power supply that has
been disconnected from the power cord connector. Although temperature
conditions above the maximum acceptable level rarely occur at initial startup,
you may encounter these conditions during extended operation. Long-term
monitoring functions also include independent reporting of DC-output voltage
problems.
