11. Front Panel

The common front panel feature set conforms to the industry standard SSI 2x12 connector
specification, but includes an extension to this connector to support 3
LEDs. The longer connector is a 2x15 right angle header, which includes missing pin locations
at pins 25 & 26.
While the front panel board uses a custom 2x15 connector, the baseboard simply adds a 2x2
connector in-line (and appropriately spaced) with the existing SSI 2x12 connector. Boards that
support Quad LAN can populate the 2x2 connector, and boards that only support Dual LAN can
depopulate the connector.
