Abstract
In one embodiment, a hot swappable power supply device comprises power supply circuitry for receiving input power at a first voltage and for providing output power to a voltage bus at a second voltage, a latch element that selectively mechanically couples the power supply device to an external frame structure, and a control circuit, wherein the control circuit responds to a power down signal by powering down the power supply circuitry and releasing mechanical coupling to the external frame structure by the latch element after energy has been substantially dissipated from the power supply circuitry.
