1.5.1 Power Supply Options
The power cabinet and the rack-mountable dual power feed option for the M8000 
server are offered as power supply options. 
The power cabinet enables dual power feed or three-phase power feed.
The rack-mountable dual power feed option for the 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 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 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 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.
TABLE 1-6 lists specifications of the power cabinet.
