Main Logic Board Jumpers
Jumper pins allow to set specific server parameters. They are set by changing the pin location of jumper blocks.
A jumper block is a small plastic-encased conductor (shorting plug) that slips over the pins. Place the jumper
over the two pins designated for the desired setting. Press the jumper evenly onto the pins. Be careful not to
bend the pins.
CAUTION
Do not touch any electronic component unless you are safely grounded. Wear a grounded
wrist wrap or touch an exposed metal part of the server’s chassis.
