Server does not respond to the Power On or Reset switch.

Verify that the Power Disable Setting in the System Configuration Utility is set to Enable, and that Secure Mode is set to Disable.

If the Power On and Reset switches are set to Enable, and Secure Mode is set to Disable, have the system serviced.

Intermittent Problems Action

A problem occurs only occasionally and is difficult to detect.

Verify that:

1.All cables and cords are securely connected to the rear of the system and attached options.

2.When the system is turned on, air is flowing from the rear of the system at the fan grill. If there is no air flow, the fan is not working. This causes the system to overheat and shut down.

3.The last external device in each SCSI chain is terminated correctly. (See “SCSI Drives” on page 159 for more information about SCSI terminators.)

If the items above are correct, have the system serviced.

Keyboard, Mouse,

All or some keys on the keyboard do not work.

1.Make sure the keyboard cable is properly connected to the system.

2.Make sure that the system and the monitor are turned on.

If the items above are correct, have the system serviced.
