CAUTION:
The AC power distribution within a rack ensures a balanced load to each PDU and reduces the
possibility of an overload condition. Changing the cabling to or from a PDM could cause an overload
condition. HP supports only the AC power distributions defined in this user guide.

Figure 19 Rack PDM
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 20).
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 Controller 1 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.
