1. A sub-rack for converting cooling pattern of a side-to-side cooled equipment, comprising:
a first unit comprising a first cover, a front side wall that is disposed at a front side of the first cover and has at least one inlet vent, a rear side wall that is disposed at a rear side of the first cover and has at least one outlet vent, and an air flow guiding member comprising a division plate that protrudes from the first cover towards the side-to-side cooled equipment to be mounted in the sub-rack and divides the first unit into a first portion and a second portion, wherein the at least one outlet vent of the first unit is proximate the first portion and the at least one outlet vent of the first unit is proximate the second portion, and wherein the air flow guiding member operates to guide an air flow introduced from the at least one inlet vent of the front side wall to one of a first lateral side and a second lateral side of the first unit before exiting the at least one outlet vent of the rear side wall;
a second cover disposed at the first lateral side of the first unit; and
a third cover disposed at the second lateral side of the first unit;
wherein at least one cover of the second cover and the third cover is disposed to be movable relative to the first unit in a lateral direction via a first moving mechanism.
