The information machine room universal equipment support comprises a support plane, a side plate, a front panel, front panel installing holes, a front fixing groove and a rear fixing groove. One side of the support plane is fixedly provided with the side plate. The support plane and the side plate are arranged in an L-shaped way. One end of the side plate is fixedly provided with the front panel. Two front panel installing holes are arranged on the front panel. The front fixing groove and the rear fixing groove are arranged on the side plate. The support which is suitably used for installation supporting operations of different equipment makes installation operations of conventional various types of supports with different structures replaced. Brainwork and manual labor can be reduced. Meanwhile, the problems that spare parts from an original factory are hard to buy and once an original support is damaged, the equipment cannot be installed are solved.
