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 19 (page 24) ).
•
PDMs A1 through A4 connect to receptacles A through D on PDU A. Power cords connect
these PDMs to the left power supplies on the disk enclosures and to the left power supplies on
the controllers.
•
PDMs B1 through B4 connect to receptacles A through D on PDU B. Power cords connect
these PDMs to the right power supplies on the disk enclosures and to the right power supplies
on the controllers.
NOTE: The locations of the PDUs and the PDMs are the same in all racks.
