b.When you have a monitor, keyboard, and mouse attached and the NAS 200 engine passes POST, one beep sounds. If the NAS 200 fails POST, a series of beeps sound (see “POST beep code descriptions” on page 87 for more details) and an error message appears on the monitor screen.

2.Power on the NAS 200 and watch the screen.

3.When the message F2 for Diagnostics appears, press F2. If a POST error is encountered, a series of beeps sound and an error message appears on the monitor screen.

4.Type in the appropriate password; then, press Enter. If a system error is encountered, the Configuration/Setup screen appears. Press Esc to start the Diagnostic program.

Note: To run the diagnostic programs, you must start the NAS 200 with the highest level password that is set. That is, if an administrator password is set, you must enter the administrator password, not the power-on password, to run the diagnostic programs.

5.Select either Extended or Basic from the top of the screen. (PC-Doctor 2.0 with

acopyright statement appears at the bottom of this screen.)

6.When the Diagnostic Programs screen appears, select the test you want to run from the list that appears; then, follow the instructions on the screen.

Notes:

a.Press F1 while running the diagnostic programs to obtain Help information.

Also press F1 from within a help screen to obtain online documentation from which you can select different categories. To exit Help and return to where you left off, press Esc.

b.If the NAS 200 engine stops during testing and you cannot continue, restart the NAS 200 engine and try running the diagnostic programs again.

c.If you run the diagnostic programs with either no mouse or a USB mouse attached to your NAS 200 engine, you will not be able to navigate between test categories using the Next Cat and Prev Cat buttons. All other functions provided by mouse-selectable buttons are also available using the function keys.

d.You can test the USB keyboard by using the regular keyboard test. The regular mouse test can test a USB mouse. Also, you can run the USB hub test only if there are no USB devices attached.

e.You can view NAS 200 engine configuration information (such as system configuration, memory contents, interrupt request (IRQ) use, direct memory access (DMA) use, device drivers, and so on) by selecting Hardware Info from the top of the screen.

f.You cannot use the diagnostics program to test adapters. Use the procedure outlined in “Adapter troubleshooting and diagnostics” on page 62.

When the tests have completed, you can view the Test Log by selecting Utility from the top of the screen.

If the hardware checks out OK but the problem persists during normal NAS 200 operations, a software error might be the cause. If you suspect a software problem, refer to the information that comes with the software package.
