Description

The EX4400 24-port PoE++ model is a fixed 1U access switch for secure, cloud-ready enterprise campus, branch and data centre networks. It suits high-power PoE++ deployments such as Wi-Fi access points, IP cameras, IoT devices and unified communications endpoints, and it runs Junos OS.

It provides 24 x 10/100/1000BASE-T PoE++ ports delivering up to 90 W per port, plus 2 x 100GbE QSFP28 built-in uplink and Virtual Chassis ports. This variant uses a 1050 W AC power supply with a 783 W PoE budget in a single-PSU configuration, rising to 1806 W with two supplies. Packet switching capacity is 324 Gbps unidirectional, and up to 10 members can be joined in a Virtual Chassis over a 400 Gbps interconnect. The hardware SKU carries the base feature set, and MACsec AES-256 is available through a separate optional licence.

An optional extension module adds 4 x 1/10GbE or 4 x 10/25GbE uplinks. The switch also supports the 1600 W AC and 2000 W DC power supplies and requires Junos OS 21.1R1 or later.
