4.1.17 Power input (DC version)
Power is supplied from an external source. The voltage of the external source needs
to be in the range +18V to 30V. This enters the board via an 8-pin connector
(Receptacle, mini fit 8 Way, Molex) JP14.

The external source is input to a DC-DC converter module, which produces +/-12V
to the TIM sites. It is also used as an input to two DC-DC converters that produce
the +5V, +3.3V, +2.5V and 1.5V supply to the TIM sites, carrier FPGA and other on-
board devices.
When using a +24V input, the power consumption of an unpopulated SMT148X is
approximately 6W.
Alternatively, the input power can be provided at +9 to 18V (using alternative DCDC
parts). Contact Sundance for further information.
The fan connectors, FAN1-4, are powered directly from the input supply.
