3.5 WAFER-8522 Motherboard On-board Jumpers
NOTE:
A jumper is a metal bridge used to close
an electrical circuit. It consists of two or
three metal pins and a small metal clip
(often protected by a plastic cover) that
slides over the pins to connect them. To
CLOSE/SHORT a jumper means
connecting the pins of the jumper with
the plastic clip and to OPEN a jumper
means removing the plastic clip from a
jumper.
