The cabinet has 12 mounting holes (to a wall, originally plugged). In the lower part of the cabinet there are 6 holes with 23 mm diameter. Four of them are plugged, the other two should be fitted with the included cable fittings. Rack rails with runners inside the cabinet allow for easy installation of equipment. The distance from the rack rails to the bottom is 54 cm, and to the top 20 cm, which allows free access to the equipment and safety of operations with delicate components such as fiber-optic patch cords.
