2-4 Front Jumper Location and Settings
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 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.

Note: Unless explicitly instructed otherwise by the manufacturer, do not move the
jumpers from their default locations of pins 1-2. Doing so will likely cause the card
to become disabled.
