NOTICE
l Leave at least 50 mm of clearance around the router for heat dissipation.
l Seen from the front panel of the router, the airflow of the router is left to right.
l If multiple routers are installed in a cabinet, it is recommended that at least 1 U of space (1
U = 44.45 mm) be kept between two routers. These routers must have the same airflow
direction; otherwise, heat dissipation is affected by hot air circulation.
