the left-most slot, as viewed from the front (refer to Figure 2-5. Each of the
backplane connectors of a set of four slots is connected in parallel and is
supplied by one pair of the AC/DC input lines. In a double-width and triple-width
module, the module connector is located so that it mates to a backplane
connector in the right-most slot, as viewed from the front of the Mainframe. Refer
to Figure 2-4 for a diagram showing the power distribution from the input
connector to the twelve Mainframe slots.
