1. A system for automated equipment cabinet leveling, comprising:
a foot leveling device for each foot of an equipment cabinet comprising a plurality of cabinet feet, each foot leveling device comprising a drive gear and a worm gear;
a motor for each foot leveling device, each motor driving the worm gear of one of the feet leveling devices;
a controller interfacing with each of the motors and controlling an operation of each motor; and
a sensor positioned on a portion of the equipment cabinet to be leveled that detects an orientation of the equipment cabinet and provides orientation data to the controller;
wherein the foot leveling device interfaces with a foot shaft of the cabinet foot by a drive shaft driven by the drive gear;
wherein the controller:
drives each of the motors in a first direction to retract the cabinet feet until each of the motors skips or stalls;
drives each of the motors in a second direction at a first amperage level to extend each of the cabinet feet until each of the motors skips or stalls;
receives orientation data from the sensor;
identifies one of the motors to drive to level a surface of the equipment cabinet based on the orientation data; and
drives the identified motor at a second amperage level that is greater than the first amperage level in the second direction to level the surface of the equipment cabinet by extending the cabinet foot associated with the identified motor, wherein the second amperage prevents the identified motor from skipping or stalling.
