Rack AC power distribution
The power distribution in an Enterprise Virtual Array rack is the same for all variants. The site AC input
voltage is routed to the dual PDU assembly mounted in the rack lower rear. Each PDU distributes AC to a
maximum of four PDMs mounted on the left and right vertical rails (see Figure 27 ).
• PDMs 1 through 3 connect to receptacles A through D on PDU 1. Power cords connect these
PDMs to the number 1 drive enclosure power supplies and to the upper controller enclosure.
• PDMs 4 through 6 connect to receptacles A through D on PDU 2. Power cords connect these
PDMs to the number 2 drive enclosure power supplies and to the lower controller enclosure.
NOTE:
The locations of the PDUs and the PDMs are the same in all racks.
