Ethernet Segment Bank Selector
The Ethernet segment bank selector on the Main Logic Module (see
Figure 2-1), consisting of three rows of 20 pins (J6) and a jumper,
determines whether the module connects to Ethernet segments 1
through 6 or segments 7 through 12 at power up. When the jumper
is installed between the bottom and middle rows of pins, the module
has access to segments 1 through 6 (the factory default setting); when
the jumper is installed between the top and middle rows of pins, the
module has access to segments 7 through 12.
