Setting the system board jumpers
The system board has three jumpers. Each of these jumpers has a specific function described in the sections below.
The CMOS Clear jumper
The CMOS Clear jumper on the system board (pins 1 through 3 of jumper J2J1) lets you clear all BIOS Setup settings. (See the figure on page 6 for the location of the jumper.)
The following table shows the settings required to perform this task. Make sure you turn off the server and unplug the power cord before moving the jumper.
