This indicates that your boot microprocessor has failed, or your board or speaker subsystem might contain a failing component. If t system continues through POST with no errors, have the system servi no video appears, the boot processor has failed; replace the b

Note: If the Netfinity 5000 server has only one microprocessor insta that microprocessor is the boot processor. If the Netfinity server has two microprocessors installed, the microprocessor i secondary microprocessor connector is the boot processor and microprocessor in the primary microprocessor connector is the application processor.

One short	beep
If	one beep		occurs after your Netfinity 5000 server successfully
POST	(that	is,	after	the System	POST Complete (OK)	light on the
