The Juniper EX4100-48T-AFI is a 48-port Gigabit access switch with back-to-front airflow. It serves wired devices that do not need power from the switch, while separate uplink and Virtual Chassis interfaces provide higher-speed network connections. The AFI suffix distinguishes its cooling direction from the standard front-to-back model.

Choosing your configuration
Choose the -48T-AFI for non-PoE Gigabit access where the rack requires air to enter at the rear and exhaust at the front. If access points, phones or cameras need switch-supplied power, select a suitable PoE model instead. Confirm optics, the Virtual Chassis design and any software or management subscriptions with Link US when ordering.
