Three-phase power feed

Three-phase power feed is a method of receiving power feeds from a three-phase
power supply rather than a single-phase power supply.
The customer needs to prepare an external power distribution unit for three-phase
power feed for the SPARC M10-1, M10-4, or M10-4S. There are two types of
three-phase power feed: three-phase star connection and three-phase delta connection.
An expansion rack can have three-phase power feed according to the selection of the
three-phase star type or three-phase delta type. The power distribution units of an
expansion rack are mounted inside the rack.
