Patent ID: 8286010

Claim:
A data center rack comprising: an alternating current (AC) input to receive AC power from AC mains; a power supply to receive the AC power from the AC input and to generate direct current (DC) power to provide to one or more data center rack components insertable within the data center rack; a conductor connecting the AC input to the power supply; a first high-current junction at which the AC input is removably connected to the conductor, where a high current passes from the AC input to the conductor; a second high-current junction at which the power supply is removably connected to the conductor, where the high current passes from the conductor to the power supply; a first voltage sensor to detect a first voltage at the first high-current junction; a second voltage sensor to detect a second voltage at the second high-current junction; and, a controller to perform a predetermined action in response to one or more of the first voltage sensor detecting the first voltage being greater than a predetermined threshold voltage and the second voltage sensor detecting the second voltage being greater than the predetermined threshold voltage.
