Troubleshooting the Installation
Your Cisco12008 was subjected to extensive testing and burn-in before being shipped from
the factory. However, if you encounter problems starting up the router, the information in
this chapter will help you to isolate the probable cause.
This chapter contains the following sections:
•Troubleshooting Overview
•Troubleshooting the Power Subsystem
•Troubleshooting the Processor Subsystem
•Troubleshooting the Cooling Subsystem
•Additional Troubleshooting Reference Information
In this chapter, it is assumed that you are troubleshooting the initial Cisco 12008 system
startup, and that the system is in the original factory configuration. If yo u ha v e removed or
replaced components or changed any default settings, the recommendations in this chapter
might not apply.
At initial system startup, you should verify the following:
•External power cables are connected, and proper source power is being supplied.
•The card cage fan tray and the power supply fan tray are operating.
•The system software boots successfully.
•The RP and the line cards are properly installed in their slots; each card initializes (is
enabled by system software) without problems.
