These procedures can often reveal the source of a problem or indicate the correct starting point for servicing the system.

  • Page 3: Observing The Boot Routine

    You can run the system diagnostics from the utility partition by pressing <F10> during startup (this is the suggested method in most situations) or from a set of diskettes created from the Dell OpenManage Server Assistant CD. To observe problem indications during the boot routine, perform the following steps: 1.

  • Page 4: Running The System Diagnostics

    For a quick check of the system, select Test All Devices and then select Quick Tests. This option runs only the device tests that do not require user interaction and that do not take a long time to run. Dell recommends that you choose this option first to increase the chance of tracing the source of the problem quickly.
