The Superdome Enclosure is designed to support N+N redundancy of the power supplies. To retain dual
source redundancy in conjunction with the power supply redundancy of Superdome 2, it is necessary to
connect all six power supplies located left of center (three top and three bottom) to one source and all six
power supplies located right of center (three top and three bottom) to the other source.
There are nine AC power connection options offered in Superdome Enclosures. These can be divided into
three main configurations
• Single Phase only (16A/20A, single phase cords that plug directly into wall sockets)
− Connectors on back of the compute enclosure are IEC60320-C19:
− A total of 12 single phase power cords are necessary to power the 12 power supplies in the
Superdome Enclosure. (power option #001)
− To limit the number of power cords exiting the rack (decrease from 12 cords to 4 cords) it
is possible to use a single phase IEC309 63A Power Distribution Units (PDUs) for power
cord aggregation. (power option #006)
− Power option #010 is only available in Japan. There are 6 NEMA L6-30P single phase
PDU's at the bottom of the rack. NOTE: Power option #010 is not available with the 36u
rack.
• Below is a photo of the rear of a Superdome Enclosure with the single phase power interface
modules installed, they are visible at the extreme top and bottom of the unit:
• Single and Three Phase mix (single phase cables within the rack connected to the PDU, three phase
cables to customer supplied receptacles)
