Abstract:
A hot-swappable power supply that electrically plugs into a rack, the power supply comprising:at least one circuit board;a housing assembly, said housing assembly having a substantially square rear side thereby allowing at least partial insertion of the power supply into the rack in at least a first, a second, a third, and a fourth orientations;at least a first connector accessible from said rear side, said first connector having at least one pin which extends from said rear side by a first amount, said pin in electrical communication with said circuit board, said first connector adapted to couple with a connector in the rack;a first key assembly extending from said rear side by a second amount, said first key assembly configured to permit said power supply to be fully inserted into the rack in a first orientation; anda standoff assembly including at least four standoffs extending from said rear side by a third amount greater than said first amount and greater than said second amount, where the standoff assembly protects the first connector and the first key assembly when rested on the rear side, but allows the first connector and the first key assembly to couple with the connector in the rack when inserted in the first orientation, where the standoff assembly includes:a first standoff spaced a first distance from a first side of the housing and a second distance less than the first distance from a second side of the housing, where the second side of the housing is adjacent to the first side of the housing;a second standoff spaced at about the second distance from the second side of the housing and at about the second distance from a third side of the housing, where the third side of the housing is opposite to the first side of the housing;a third standoff spaced a third distance different than the first distance from the first side of the housing and at about the third distance from a fourth side of the housing, where the fourth side is opposite to the second side of the housing; anda fourth standoff positioned about the third distance from the third side of the housing and at about third distance from the fourth side of the housing.
