Identifying Cisco 7507 and Cisco 7507-MX 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.
With the exception of the system blower, LEDs indicate all system states in the startup sequence. By
checking the state of the LEDs, you can determine when and where the system failed in the startup
sequence. Use the following descriptions to isolate the problem to a subsystem, and then proceed to the
appropriate sections (indicated in each description) to try to resolve the problem.
When you start up the system by turning on the power supply switches, the following should occur:

and that the blower is faulty, contact a customer service representative. If the system blower does
not function properly at initial startup, there are no installation adjustments that you should make.
