5.5 Jumper Settings
NOTE:
A jumper is a metal bridge that is used to
close an electrical circuit. It consists of
two 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.
Before the MXGD is installed in the system, the jumpers must be set in accordance with
the desired configuration. The jumpers on the MXGD are listed in Table 5-1.
