A7N8X-E System Panel Connectors

System Power LED Lead (Green 3-1 pin PLED)

This 2-pin connector connects to a chassis-mounted switch to allow the use of the keyboard lock feature.

System Warning Speaker Lead (Orange 4-pin SPKR)

This 4-pin connector connects to the case-mounted speaker and allows you to hear system beeps and warnings.
