To set each jumper switch, you have to bridge the two pins in the respective
column of the grid with a plastic shunt. Shunts are already attached to the
jumper switches in their default configurations.

Jumper switches
n The plastic shunts actually contain metal for bridging the two pins of a jumper switch,
creating an electrical connection between them when attached. When removed, the
jumper switch is set to "OFF ." Store unused shunts in a safe place where they will not
be lost.
Use a pair of long-nosed pliers to attach or detach the shunts accordingly.
However, make sure that the computer is switched off when doing so.
