Configuring Your System
Moving System Board Jumpers
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.
Notice: Observe static precautions. Use an antistatic
wrist strap.
To configure the system board options:
1. Power off the system and remove the top cover as
described in Chapter 5 of this guide.
2. Check to ensure the system power cord is removed
from the back of the system.
3. Locate the position of the jumpers on the system
board you are changing. Refer to Figure 4-3.
4. To change a jumper setting, use a pair of needle-
nose pliers or your fingers to remove the jumper
from its current location. 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 to
Table 4-8 for system board jumper settings.
5. Record changes to the system board jumpers in Table
4-8.
6. Install the system top cover and power up the
system using procedures in chapter 5 of this guide.

the system board.
