A.7 Front Jumper Locations and Pin Definitions
Explanation of Jumpers
To modify the operation of the backplane, jumpers can be
used to choose between optional settings. Jumpers create
shorts between two pins to change the function of the con-
nector. Pin 1 is identified with a square solder pad on the
printed circuit board. Note: On two pin jumpers, "Closed"
means the jumper is on and "Open" means the jumper is
off the pins.
