Description

The EX4400 is a fixed 1U campus and enterprise access switch from the Juniper EX Series. This EX4400-24P-S is the spare chassis variant, suited to replacing an existing EX4400-24P or building out an access layer that needs high-power PoE for Wi-Fi access points, cameras, IoT and other 802.3bt devices.

It provides 24 10/100/1000BASE-T PoE++ ports delivering up to 90 W per port, plus 2 built-in 100GbE QSFP28 ports for uplinks or Virtual Chassis. One extension module slot accepts the EX4400-EM-4S (4x10G SFP+), EX4400-EM-4Y (4x25G SFP28) or EX4400-EM-1C (1x100G QSFP28). Packet-switching capacity is 324 Gbps unidirectional, with a 400 Gbps Virtual Chassis interconnect supporting up to 10 members as one logical device. This spare chassis SKU is supplied without fan modules or power supplies, so it needs two fan modules and one or two power supplies to operate.

It supports 1050 W AC, 1600 W AC and 2000 W DC power supplies. With two 1050 W AC supplies the PoE budget is 1440 W. It runs Junos OS from release 21.1R1.
