    Product Description

    The Juniper Networks® EX4400 line of Ethernet switches offers a secure, cloud-ready portfolio of access switches ideal for enterprise campus and data center networks. The EX4400 switches combine the simplicity of the cloud, the power of Mist AI™, and a robust hardware foundation with best-in-class security and performance to deliver a differentiated approach to access switching in the cloud, mobile, and IoT era. With Juniper Mist™ Wired Assurance, the EX4400 can be effortlessly onboarded, configured, and managed from the cloud. This simplifies operations, improves visibility, and ensures a much better experience for connected devices.

    Key features of the EX4400 include:
    • Cloud-ready, driven by Mist AI with Juniper Mist Wired Assurance and Marvis Virtual Network Assistant
    • Ethernet VPN-Virtual Extensible LAN (EVPN-VXLAN) to the access layer
    • Media Access Control Security (MACsec) AES256
    • Power over Ethernet (PoE)++ (90W per port)/PoE
    • Standards-based microsegmentation using group-based policies (GBP)
    • Flow-based telemetry to monitor traffic flows for anomaly detection
    • 10-member Virtual Chassis support
    Offering a full suite of Layer 2 and Layer 3 capabilities, the EX4400 supports a variety of applications, including campus, branch, and data center top-of-rack deployments. As requirements grow, Juniper's Virtual Chassis technology allows up to 10 EX4400 switches to be seamlessly interconnected and managed as a single device, delivering a scalable, pay-as-you-grow solution for expanding network environments.

    The EX4400 line includes:
    • The EX4400-48F, which offers 12 x 10GbE and 36 x 1GbE fiber access ports
    • The EX4400-24T, which offers 24 x 1GbE non-PoE access ports
    • The EX4400-24P, which offers 24 x 1GbE PoE access ports, delivering up to 90 W per port and a power budget of 1800 W
    • The EX4400-48T, which offers 48 x 1GbE non PoE-access ports
    • The EX440-48P, which offers 48 x 1GbE PoE access ports, delivering up to 90 W per port and a power budget of 1400 W
    Each EX4400 model offers 4 x 10GbE SFP+/25GbE SFP28 uplinks and two fixed 100GbE Virtual Chassis stacking ports, which can be reconfigured as Ethernet ports as needed. The switches also include high availability (HA) features such as redundant, hot-swappable internal power supplies and field-replaceable fans to ensure maximum uptime. The PoE-enabled EX4400 switch models offer standardsbased 802.3af/at/bt (PoE/PoE+/PoE++), delivering up to 90 watts on all ports.
