If your system has problems starting up, use the information in this chapter to help isolate the cause.
Problems with the initial startup are often caused by a module that has become dislodged from the
backplane or a power supply that has been disconnected from the power cord connector. Although
temperature conditions above the maximum acceptable level rarely occur at initial startup, you may
encounter these conditions during extended operation. Long-term monitoring functions also include
independent reporting of DC-output voltage problems.
Note
This chapter covers only the chassis component hardware aspects of troubleshooting. For

The system fan assembly is operating.
•
System software boots successfully.

The supervisor engine and all modules are installed properly in their slots, and each was initialized
without problems.
