CAUTION

Before doing the procedures in this section, make sure that your system is powered off and unplug the AC power cord from the back of the chassis. Failure to disconnect power before moving the jumpers can result in personal injury and equipment damage.

1.Power off the system and remove the left panel as described in Chapter 4 of this guide.

2.Check to ensure the system power cord is removed from the back of the system.

Position the jumper over the two pins for the desired setting and press it onto the pins. Be careful not to bend the pins. Refer the System Board Summary table for system board jumper settings.

4.Install the system cover and power up the system.
