Troubleshooting a Cisco 7500 Series Router

Your Cisco 7500 series router went through extensive testing and burn-in before leaving the factory; however, if you encounter problems starting up the router, use the information in this chapter to help isolate the cause. Problems with the initial startup will most likely be caused by the source power or a processor module that has become dislodged from the backplane.

Although an overtemperature or overvoltage condition is unlikely at initial startup, a discussion of environmental temperature and voltage monitoring functions is provided in the “Environmental Monitoring and Reporting Overview for the Cisco 7500 Series” section on page 2-22.

Note The procedures in this chapter assume that you are troubleshooting the initial Cisco 7500 series system startup, and that the router is in the original factory configuration. If you have removed or replaced components or changed any default settings, the recommendations in this chapter might not apply.

The Cisco 7505 uses a single RSP2 main system processor. It is also compatible with an RSP4 and RSP8 as an upgrade option.

The Cisco 7507, Cisco 7507-MX, Cisco 7513, and Cisco 7513-MX use up to two RSP2s, RSP4s, or RSP8s, or one of each. Two RSPs in any combination are required in these routers only when you have the high system availability (HSA) feature enabled; otherwise, only one RSP2, RSP4, or RSP8 is allowed.

Note The Cisco 7576 does not support HSA. Each of the two independent routers within the Cisco 7576 chassis operates with only one RSP (RSP4). When an RSP8 is used as the master device, the HSA feature functions only with another RSP8 as the slave device. Throughout this chapter, the RSP2, RSP4, and RSP8 are referred to as RSP and RSPs; where appropriate, specific differences are clearly noted.
