3.11.6 Expansion Connector
In an expanded voter system consisting of more than one chassis, this connector is cabled to the
Console Connector in the next chassis in the system. In the final voter (Expansion shelf 2 in a
three chassis system, Expansion shelf 1 for two chassis) in a system, this connector is not used.
This male 15 pin D-sub connector is labeled P3. See Figure 3-4 and Figure 3-5 for expansion
cable diagram drawings. The expansion cables may be ordered from us (the cable lengths
assume that all voters in an expanded system are located in the same rack, and separated by no
more than 3U, or 5.25”).
