Cabinet-Mounting Requirements
When installing the router in a cabinet,
Install the router in an open cabinet if possible. If you install the router in a closed cabinet,
make sure that the cabinet is equipped with a good ventilation system.
Install the router on a shelf in view of the heavy weight of the router.
Make sure that the cabinet is sturdy enough to support the weight of the router and installation
accessories.
Make sure that the size of the cabinet is appropriate for the router, and that there is enough
clearance around the left and right panels of the router for heat dissipation.
For the sake of heat dissipation and device maintenance, it is recommended that the front and
rear of the cabinet should be at least 0.8 m (31.5 in.) away from walls or other devices, and that
the headroom in the equipment room should be no less than 3 m (118.1 in.).
