The specificsegment connection for the module is determined by the
segment selectionD IP switch (described in the next section).
Segment Selection DIP Switch
DIP switch S1 on the module (see Figure2-1) is used to set the default
segment selections.Segment selection DIP switch settings are listed in
Table 2 -2. Turning a DIP switch number ON selects a particular segment
within the Ethernet segment bank. For example, turningon DIP switch
number 1 selectse ithersegment 1 or 7, depending on the positionof the
Ethernet segment bank selector jum per card.
When the jumperc ardis installed between J5 and J21, the
printedcircuit card handle is nearest the front of the module. To
installthe jumper card between J5 and J22, remove the jumper
card,rotate it 180 degrees (so that the printed circuit card handle
is nearestthe back of the module) and push it onto the pins (see
Figure2-1).
Network managementsoftware cannot override the bank
selectorsetting. The setting (segments 1–6 or 7–12) can only be
set whilethe module is outside the chassis.
If no DIPsw itchnumbers are turned on, the unit defaults to
Segments1 or 7 (depending on the position of the Ethernet
segmentbank selector jumpercard).
