Self Made Lights Out Management aka SM-LOM is a little USB Connected box, providing the user with a serial console, power cycle and reset ability. Its build using a FTDI FT232R Devel board and a little daughter board.
The idea is to use the additional CBUS pins of the FT232R chip to drive some relais. The FT232R has 4 CBUS aka General purpose i/o (GPIO) pins which can be used to e.g. driver receive and transmit leds, or to drive some relais. Those pins can be written/read via libftdi (See the example directory for bitbang_cbus.c). Then the ULN2803 open collector relais driver is used to drive the 5V Relais. To correctly program the CBUS pins you'll need the FTDI MPROG or FT_PROG utility (See here: http://www.ftdichip.com/Resources/Utilities.htm)
