Press the power cord firmly into the power
jack on the top right side of the primary
carrier’s backplane until it locks into place.
Plug the other end of the power cord into a
properly grounded three-prong wall outlet not
controlled by a switch.
Repeat Steps 7A and 7B for the expansion
carrier, plugging its cord into the same wall
outlet as the primary carrier’s cord.
To power up the control unit, push in the main
circuit breaker on the expansion carrier first,
then push in the main circuit breaker on the
primary carrier, or move the on/off switch to
the “on” position (“l”).
