3-26 Configuring Your System
Moving System Jumpers
!
CAUTION
Before doing the procedures in this section, make sure that
your system is powered off and unplug the AC power cords
from the back of the chassis. Failure to disconnect power
before moving the jumpers can result in personal injury and
equipment damage.
Observe static precautions. Use an antistatic wrist strap.
To configure the system jumpers on the system board:
1. Remove the processor cover. See Removing the Processor Cover in
chapter 4. Set the processor cover aside for reinstallation later.
2. Locate the position of the system jumpers that you are changing on the
system board. To change a jumper setting, use a pair of needle-nose pliers or
your fingers to remove the jumper from its current location, see Figure 3-3.
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 3-4 and Table 3-5
for system jumper settings.

Processor Cover in chapter 4.
