Explanation of Jumpers
To modify the operation of the
serverboard, 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 cir-
cuit board. See the diagram at right
for an example of jumping pins 1 and
2. Refer to the serverboard layout
page for jumper locations.
Note 1: On two-pin jumpers, "Closed"
means the jumper is on and "Open"
means the jumper is off the pins.
