The rack-mountable dual power feed option for the SPARC Enterprise M8000 server receives power from two external AC power sources that are independent of each other, and duplicates the input power system.

To use a single-phase dual power feed configuration for the SPARC Enterprise M8000 server, mount the rack-mountable dual power feed option in the rack space itself. This requires a rack space with a height of 6 RUs in the cabinet. For the SPARC Enterprise M9000 server, you must add the power cabinet.

For three-phase power feed in either server, an additional power cabinet is required. Install one power cabinet for each SPARC Enterprise M8000/M9000 Server.

For details, see the SPARC Enterprise M8000/M9000 Servers Site Planning Guide.

Note – A three-phase power feed option can be installed only at the factory before shipment. A single-phase power feed cannot be changed to a three-phase power feed, or vice versa, after shipment from the factory.
