Detailed Description
17. Switches
The SP605 Evaluation board includes the following switches:
• Power On/Off Slide Switch SW2
• FPGA_PROG_B Pushbutton SW3 (Active-Low)
• SYSACE_RESET_B Pushbutton SW9 (Active-Low)
• System ACE CF CompactFlash Image Select DIP Switch S1 (Active-High)
• Mode DIP Switch SW1 (Active-High)
Power On/Off Slide Switch SW2
SW2 is the SP605 board main power on/off switch. Sliding the switch actuator from the off 
to on position applies 12V power from either J18 (6-pin Mini-Fit) or J27 (4-pin ATX) power 
connector to the VCC12_P power plane. Green LED DS14 will illuminate when the SPL605 
board power is on. See 19. Power Management for details on the on-board power system.

CAUTION! 
DO NOT plug a PC ATX power supply 6-pin connector into 
the J18 connector on the SP605 board. The ATX 6-pin 
connector has a different pinout than J18 and will damage 
the SP605 board and void the board warranty. 
DO NOT plug an auxilliary PCIe 6-pin molex power 
connector into the J18 connector as this could damage the 
PCIe motherboard and/or the SP605 board. J18 is marked 
with a NO PCIE POWER label to warn users of the poten-
tial hazard.
DO NOT apply power to J18
 and the 4-pin ATX disk drive 
connector J27 at the same time as this will damage the 
SP605 board.
