Power On/Off Slide Switch SW2

SW2 is the ML605 board main power on/off switch. Sliding the switch actuator from the
off to on position applies 12V power from either J60 (6-pin Mini-Fit) or J25 (4-pin ATX)
power connector to the VCC12_P power plane via the 1 m
resistor R346. See
Green LED DS25 will illuminate when the ML605 board power is on. See section

CAUTION!
DO NOT plug a PC ATX power supply 6-pin connector into
the J60 connector on the ML605 board. The ATX 6-pin
connector has a different pinout than J60 and will damage
the ML605 board and void the board warranty.
DO NOT plug an auxilliary PCIe 6-pin molex power
connector into the J60 connector as this could damage the
PCIe motherboard and/or the ML605 board. J60 is marked
with a NO PCIE POWER label to warn users of the poten-
tial hazard.
DO NOT apply power to J60 and the 4-pin ATX disk drive
connector J25 at the same time as this will damage the
ML605 board.
