4.5 Jumpers

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

JRU1. To set Pin 2 of JFP1 for BMC reset support, close Pins 3 and 4 of jumper JRU1. Please
