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 WAFER-LX is installed in the system, the jumpers must be set in accordance

with the desired configuration. The WAFER-LX motherboard has six on-board jumpers.

The jumpers are described in Table 5-2 and shown in Figure 5-2.
