Description

The EX4400-48MP is a 1U multigigabit access switch from the Juniper EX4400 line, built for campus, branch and data-centre top-of-rack access. It suits PoE++ and multigigabit endpoints such as Wi-Fi 6/6E/7 access points, IP cameras and IoT devices, and it can be managed from the cloud with Juniper Mist Wired Assurance.

This variant has 12 ports at 100M/1/2.5/5/10GbE and 36 ports at 100M/1/2.5GbE, all with IEEE 802.3bt PoE++ delivering up to 90 W per port. The PoE budget is 1300 W with one power supply and 2200 W with two. Two 100GbE ports are used for Virtual Chassis by default and can also serve as uplinks, while an optional extension module adds 4 ports of 1/10GbE SFP+ or 10/25GbE SFP28. Switching capacity is 510 Gbps unidirectional and 758 Mpps at Layer 2/3.

It runs Junos OS with the Standard Flex licence tier, and additional features need a Flex Advanced or Premium licence. Up to 10 units can form a Virtual Chassis, and MACsec AES-256 is supported on user-facing interfaces.
