4.9 Jumper Settings

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.

The following jumpers can be found on the motherboard installed in the AFL-4

Series-N270. Before the AFL-4 Series-N270 is installed, the jumpers must be set in

accordance with the desired configuration. The jumpers on the AFL-4 Series-N270

motherboard are listed in

Table 4-1.
