Ethernet Segment Bank Selector
The Ethernet segment bank selector (see
), consisting of three
rows of 20 pins (labeled J5, J21 and J22) and a jumper card, determines
whether the module connects to Ethernet segments 1 through 6 or
segments 7 through 12 at power up. When the jumper card is installed on
the two rows of pins nearest the front of the module (using J21), the
module has access to segments 1 through 6 (the factory default setting);
when the jumper card is installed on the two rows of pins nearest the back
of the module (using J22), the module has access to segments 7 through
12.
