Juniper EX4400 Switch

The EX4400 switches combine the simplicity of the cloud, the power of Mist AITM, 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 MistTM 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
‣    End-to-end encryption using Media Access Control Security (MACsec) AES256
‣    IEEE 802.3bt Power over Ethernet (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 enables a variety of deployments, 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 consists of five SKUs:
‣    The EX4400-48F, which offers 12 x 10GbE SFP+ and 36 x 1GbE SFP 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 with an overall       total 1440W of PoE power budget (using two power supplies)
‣    The EX4400-48T, which offers 48 x 1GbE non PoE-access ports
‣    The EX4400-48P, which offers 48 x 1GbE PoE access ports, delivering up to 90 W per port with an overall       total 1800W of PoE power budget (using two power supplies)

Each EX4400 model offers a choice of optional 4 x 1/10GbE SFP+ and a 4 x 10/25GbE SFP28 extension module. The EX4400 switches include two dedicated 100GbE ports to support virtual chassis connections, which can be reconfigured to be used as Ethernet ports for uplink connectivity. EX4400 switches also include high availability (HA) features such as redundant, hot-swappable power supplies and field-replaceable fans to ensure maximum uptime.

In addition, PoE-enabled EX4400 switch models offer standards-based 802.3af/at/bt (PoE/PoE+/PoE++) for delivering up to 90 watts on any access port. The EX4400 switches can be configured to deliver fast PoE capability, which enables the switches to deliver PoE power to connected PoE devices within a few seconds of power being applied to the switches.
