Detailed Description
18. Switches
The ML605 Evaluation board includes the following switches:
Power On/Off Slide Switch SW2
FPGA_PROG_B SW4 (active-Low)
SYSACE_RESET_B SW3 (active-Low)
System ACE CF CompactFlash Image Select DIP Switch S1 (active-High)
MODE, Boot EEPROM Select and CCLK Osc Enable DIP switch S2 (active-High)
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 1m
Ω 1% 3W series current sense
resistor R346. See “22. System Monitor,” page 68 for further details on 12V input current
sensing. Green LED DS25 will illuminate when the ML605 board power is on. See section
“21. Power Management,” page 65 for details on the onboard power system.

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 d
amage the
ML605 board.
