Looking things over

In any complex system, there is potential for a forgotten connection, a forgotten switch, or a loose connector. If you try to start up the server and it does not start up, perform the following checks:

•Is the power cord connected to the CPU system and an AC outlet?•Is the AC outlet supplying power?•If a power strip is used, is it switched on? Is the circuit breaker set?

•Does the voltage selection switch on the system’s power supply reflect the proper voltage?

Verifying your configuration

If your system is not operating correctly, the BIOS may contain an invalid configuration parameter. Enter the BIOS program and check your configuration settings. The BIOS Setup utility, configuration fields, and the options for those fields are provided in the Maintaining and Troubleshooting Guide.

Troubleshooting guidelines

As you troubleshoot your system, keep the following guidelines in mind:•Never remove the system covers while the system is on.

•Do not attempt to open the monitor. It is extremely dangerous. Even if the monitor power is disconnected, stored energy in the monitor’s components can cause a painful or harmful shock.

•If a peripheral such as the keyboard, mouse, drive, or printer does not work, ensure that all connections are secure.

•If the screen displays an error message, write it down word-for-word. You may be asked about it when calling Technical Support.

•Only qualified personnel should open the system for maintenance.

•If you are qualified to maintain the system yourself, make certain you are properly grounded before opening the system chassis.

Important!

If the CMOS has been corrupted by a power outage or an interrupted flash update and you plug the system into a power outlet, it will power up immediately. This is normal.
