Be sure that cables and other equipment do not block the air intake or outflow on an Extreme Networks router.
Depending on other conditions in the equipment room, it may be possible to install the routers closer to each other; consult your Extreme Networks Customer Support representative for guidance.
Leave at least 3 inches (8 cm) of clear space in front of the air intake and outflow vents on the sides of the router.
Airflow moves from side to side. For proper airflow through an E4G series router, leave clear space on the left and right sides of the router.
