⚠ CAUTION!
Power On/Off Slide Switch
[Figure 1, callout 20]
The VEK280 board power switch is SW13. Sliding the switch actuator from the off
to the on position applies 12 VDC power from the 2x3 6-pin mini-fit power input
connector J16 (power from an external 120 VAC-to-12 VDC power adapter).
Important: Power to the VEK280 is mutually exclusive and only one of the two
power connections should be powered. Either J16 or both JP1 and JP2 should be
used to provide board power.
The two 2x4 8-pin (6+2) ATX power supply PCIe-type connectors JP1 and JP2 are
provided for higher power use cases.
The customer ATX supply chosen must support at least two PCIe (6+2) GPU
connections to support powering the evaluation board.
Only use a single ATX supply to support delivery of 12V to two PCIe GPU (6+2)
connectors or damage might occur.
When ATX PCIe GPU 6+2 connections are made, the 6 pin mini-fit Jr power
brick connection and onboard on/off power switch is disabled.
The green LED DS36 illuminates when the VEK280 board power switch is on. See
Board Power System for details on the onboard power system.
Do NOT plug a PC ATX power supply 6-pin connector into the VEK280
board power connector J16. The ATX 6-pin connector has a different pinout than
