Description

The EX4400 24-port multigigabit PoE++ switch is a spare chassis for the Juniper EX4400 Series. It suits enterprise campus, branch and data centre access deployments that need multigigabit PoE++ for Wi-Fi 6, 6E and 7 access points, cameras, IoT and other high-power PoE devices, as a spare or replacement unit.

The chassis provides 24 access ports running 100M/1/2.5/5/10GbE, each delivering PoE++ (802.3bt) up to 90 W, plus 2 x 100GbE QSFP28 ports for Virtual Chassis or uplinks. Switching capacity is 540 Gbps unidirectional and 1080 Gbps bidirectional. A 400 Gbps Virtual Chassis backplane allows up to 10 members to be managed as one logical device. This is the spare chassis only, with no power supplies or fan modules, so the PoE budget depends on the power supplies you fit: 753 W with one 1050 W AC supply, up to 2160 W with two 1600 W AC or 2000 W DC supplies.

An optional extension module slot adds 4 x 1/10GbE SFP+, 4 x 10/25GbE SFP28 or 1 x 100GbE QSFP28 ports using the EX4400-EM-4S, EX4400-EM-4Y or EX4400-EM-1C. The 1U unit takes 1050 W AC, 1600 W AC or 2000 W DC power supplies.
