Identifying Cisco 7505 Startup Problems

When you start up the router for the first time, you should observe the startup sequence described in the
"Starting the System and Observing Initial Conditions" section on page
more detailed description of the normal startup sequence and describes the steps to take if the system
does not perform that sequence as expected.
By checking the state of the LEDs on the power supply and processor modules (the RSP and interface
processors), you can determine when and where the system failed in the startup sequence. Use the
following descriptions to isolate the problem to a subsystem; then proceed to the appropriate sections
(indicated in each description) to try to resolve the problem.
