Moving System Jumpers

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.

the pins. Be careful not to bend the pins. Refer to Table 3-4 and Table 3-5
for system jumper settings.
