3-3 Front Jumper Locations and Pin Defi nitions
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 connector. Pin 1 is identifi ed 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.
