EX4400 Multigigabit Ethernet Switch

The Juniper Networks^® EX4400 line of Ethernet switches offers a secure, cloud-ready portfolio of access switches ideal for enterprise branch, 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 
• End-to-end encryption using Media Access Control Security (MACsec) AES256
• IEEE 802.3bz Multigigabit
• 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
• Precision Timing Protocol – Transparent clock
• 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 eight SKUs:

• The EX4400-48MP, which offers 12 x 100M/1/2.5/5/10GbE and 36 x 100M/1/2.5GbE PoE access ports, delivering up to 90 W per PoE port with an overall total 2200 W of PoE power budget (using two power supplies)
• The EX4400-24MP, which offers 24 x 100M/1/2.5/5/10GbE PoE access ports, delivering up to 90 W per port with an overall total 1776 W of PoE power budget (using two power supplies). A total PoE budget of 2160 W can be achieved with two optional 1600 W power supplies.
• 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 1806 W of PoE power budget (using two power supplies). A total PoE budget of 2160 W can be achieved with two optional 1600 W 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 2200 W of PoE power budget (using two power supplies)
• The EX4400-24X, which offers 24 x 10GbE SFP+ fiber access/distribution ports
• The EX4400-48F, which offers 12 x 10GbE SFP+ and 36 x 1GbE SFP fiber access ports

Note: EX4400-24X can be used as an access or a distribution layer switch.

Each EX4400 model offers a choice of optional 4 x 1/10GbE SFP+,  a 4 x 10/25GbE SFP28 and a 1 x 100GbE QSFP28 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. The 100GbE ports can also accept 40GbE optics for virtual chassis connection or 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. In addition, the EX4400 switches support perpetual PoE, which provides uninterrupted power to connected PoE powered devices (PDs) even when the switch is rebooting.
