Primary and Expansion Ports
There are two RJ-45 jacks on the rear panel of the jack box labeled Primary and
Expansion. The Primary jack is used to connect the jackbox to the console system with
which it is being used. A shielded 8-conductor RJ45 patch cable (recommended Zetron
part number 709-7889) is used for this. Pin 1 is to the left when looking at the port.
