Troubleshooting Strategy for Cisco 7505 Startup Problems 
Identifying Cisco 7505 Startup Problems
When you start up the router for the first time, you should observe the startup sequence described in the 
. This section contains a 
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.
