Description

The EX4400-24T is a fixed 1U access switch from the Juniper EX4400 Series, built for campus and branch access layers and for distribution or core roles in EVPN-VXLAN campus fabrics. It can be managed through Juniper Mist cloud management.

It provides 24 x 10/100/1000BASE-T non-PoE ports and two built-in 100GbE QSFP28 ports on the rear, used for Virtual Chassis interconnect or uplinks. Switching throughput is 324 Gbps unidirectional (648 Gbps bidirectional) with 482 Mpps of Layer 2 and Layer 3 forwarding. The 550 W AC power supply uses front-to-back airflow (AFO), and there is a second PSU slot for redundancy. Virtual Chassis supports up to 10 members managed as one logical device over a 400 Gbps interconnect. This base SKU runs Junos OS with the base (Standard) software feature set, with Advanced and Premium licences available separately.

A single expansion module slot accepts the EX4400-EM-1C (1x100GbE QSFP28), EX4400-EM-4S (4x1/10GbE SFP+) or EX4400-EM-4Y (4x10/25GbE SFP28) for additional uplinks. Supported from Junos OS 21.1R1.
