This chapter contains the following sections:
•

•
Additional Reference Information for Troubleshooting
The procedures in this chapter assume that you are troubleshooting the initial Cisco 12012
system startup, and that the system 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.
At the initial system boot, you should verify the following:
•
External power cables are connected, and proper source power is being supplied.
•
The system blower modules are operating.
•
The Cisco IOS software boots successfully.
•
The RP and line cards are properly installed in their slots, and each initializes (is enabled
by the system software) without problems.
