Off Position

In the OFF position, the power switch disables all modes of powering the DUT.

Power Enable Jumpers

For each power supply there are headers marked SUPPLY on one side and JACK on the other side. Appropriate placements of jumpers on these headers enables delivery of all power from either the onboard regulators or the three power supply jacks marked VCCINT, VCCO, and VCCAUX.

2. Power Supply Jacks

One method of delivering power to the DUT is by way of the power supply jacks. (Consult the Xilinx data book, http://www.xilinx.com/partinfo/datasheet.htm, for the maximum voltage rating for each device you are using.) The power supply jacks are:

VCCINT

Supplies voltage to the VCCINT of the DUT

VCCO

Supplies I/O voltages to the DUT

Each bank can be powered from one of two sources (VCCO, VCCINT) by appropriate placement of jumpers on the header

VCCAUX

Supplies voltage to the VCCAUX DUT pins
