Troubleshooting

Introduction

This chapter describes initial and system troubleshooting as well as error beep codes and
diagnostic LEDs (light emitting diodes).

Refer to the documentation supplied with additional options if you are
experiencing problems with specific options that you have installed.

Initial Troubleshooting

Follow these general procedures to troubleshoot your Digital AlphaStation 400 Series
system initially:

Check that the power indicators are on and that the fan is running.

Check the power indicator on the monitor. Also, check the monitor, keyboard, and
mouse cables to ensure that they are connected and seated properly.

Press the Halt/Reset button. If your system fails to boot, turn it off, wait 20 seconds,
and then turn it back on.

Make sure that all cables and connections are secure.

If the operating system has not loaded after two minutes, see the diagnostic LEDs
section of this chapter.

Contact Digital Services or your service provider for software- or hardware-related
problems.

__________________________ NOTE ____________________________

If you need to return a failed component, pack it in its original container and
return it to Digital Equipment Corporation or your service provider.
