2.2.7 Space Requirements
For the sake of adequate ventilation and easy equipment maintenance, you are
recommended to keep one meter of clearance between the rear/front of the switch
cabinet and the wall surface or other devices. If the optional cabinet is desired, the clear
height of the equipment room must be more than 3 meters inclusive.
