Introduction to 4100ES-S1 Cabinet, Continued
In the expansion bay, power and data are distributed via the power distribution interface
(PDI). The PDI is a wiring board (see Figure 2-5) with eight card slots, each of which can
accommodate a 4-inch (102 mm) x 5-inch (127 mm) slave card. If 4100-style
motherboards are used, they must be mounted over the PDI using a kit of metal standoffs
(part number 4100-KT0468).

IMPORTANT: AC power must be provided to the 4100ES-S1 from a dedicated branch
circuit.
