Power On/Off Slide Switch
[Figure 4, callout 18]
The VPK180 board power switch is SW13. Sliding the switch actuator from the o to the on
posion applies 12 VDC power from the 2x3 6-pin mini-t power input connector J16 (power
from an external 120 VAC-to-12 VDC power adapter).
IMPORTANT!
Power to the VPK180 is mutually exclusive and only one of the two power connecons
should be powered. Either J16 or all of JP1, JP2, JP3, and JP4 should be used to provide board power.
The four 2x4 8-pin (6+2) ATX power supply PCIe-type connectors JP1, JP2, JP3, and JP4 are
provided for higher power use cases.
• The customer ATX supply chosen must support at least four PCIe (6+2) GPU connecons to
support powering the evaluaon board.
• Only use a single ATX supply to support delivery of 12V to four PCIe GPU (6+2) connectors or
damage might occur.
• When ATX PCIe GPU 6+2 connecons are made, the 6 pin mini-t Jr power brick connecon
and onboard on/o power switch is disabled.
The green LED DS36 illuminates when the VPK180 board power switch is on. See Board Power
System for details on the onboard power system.
