The power input connector (Molex 39-28-1083, MINI-FIT, 8-way) pin-out is shown
here:

There are four user LEDs directly connected to the FPGA.

The default Xilinx Spartan-3 FPGA firmware provided by default with the SMT111
drives the LEDs to monitor some "health" status. This feature is coded in the FPGA
firmware and cannot be switched off, unless the firmware is modified.
When powering-off and then powering-on the SMT111 carrier board, the Xilinx
Spartan-3 FPGA (located on the SMT111) configures from a Xilinx PROM. Once the
configuration is successful, you should see a red LED flashing at regular intervals
(the first LED down from the USB connector). You should also see D1, D2, D3 and D4
"ON". They are the 4 LEDs next to the power connector (JP2).
