Troubleshooting

If your system has problems during start up or operation, use the information in this chapter to help isolate the cause. Problems with the initial startup are often caused by a switching module that has become dislodged from the backplane or a power cord that is disconnected from the power supply.

Although temperature conditions above the maximum acceptable level rarely occur at initial startup, some environmental monitoring functions are included in this chapter because they also monitor power supply output voltages.

Information about troubleshooting software features and configuration problems is not discussed in this chapter.

More up to date information can be found in the release notes or Error Message Decoder tool. Information specific to your software release can be found in the software configuration guide for that release, or in the system message guide for your release.
