There are three screw holes on both the right and left sides of the rear, and upper part of the access
controller for installing the bearing screws. You need to choose a proper hole to install a bearing screw
to each side. The rear mounting brackets can support the weight of the access controller through firm
contact with the bearing screws.
4) Determine the position for installing the access controller on the rack. Use screws and the
corresponding cage nuts to fix the rear mounting brackets to the rear square-hole rack rails, as
