Troubleshooting Hardware
This section discusses procedures for connectivity problems related to booting. It describes specific
booting symptoms, the problems that are likely to cause each symptom, and the solutions to those
problems.
Cisco 7500 Series Startup
When you start up a Cisco 7500 series router, the following should occur:
•
The AC (or DC) OK LED should go on immediately and should remain on as long as the system is
receiving power.
•
The blower should be operating.
•
The Route Switch Processor (RSP) and front-panel Normal LEDs should go on (to indicate normal
system operation) and should remain on during system operation; the CPU Halt LED should remain
off.
•
The Enabled LED on each interface processor should go on (to indicate that the RSP has completed
initialization of the interface processor).
