3.2 Power Supply
The power supply of the hardware module is realized via a 2x8-pin connector (Molex PS 43045-1619,
mating connector: Molex PS 43025-16xx). The 12 volt supply is needed for PCI-Express cards and for the
fan connector. COM3 RXD and TXD can also be used for connecting a second power supply unit, e. g.
for UPS. As an ordering option SMBus signals SCL/SDA can be provided (replacing COM3 TXD/RXD).
