Next you may want to install external switches to monitor and control the mainboard. These features are completely optional — install them only if you need them. The front panel connector (JP6) is an 16-pin male, dual in-line header and provides connections for a speaker, hard disk access indicator and an input switch for resetting the card.

Speaker

The mainboard can drive an 8Ω external speaker at 0.5 watts. If there is no external speaker, the SBC-776 provides an onboard buzzer as an alternative.

LED interface

The front panel LED indicator for hard disk access is an active low signal (24 mA sink rate).
