3-26 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.
Observe static precautions. Use an antistatic wrist strap.
To configure the system board options:
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.
3.
Locate the position of the jumpers on the system board you are
changing. 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 the
System Board Summary table for system board jumper settings.
4. Install the system cover and power up the system.
