Product Description
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:

EX4400-48F, offers 12 x 10GbE SFP+ and 36 x 1GbE SFP fiber access ports
Cloud-ready, driven by Mist AI with Juniper Mist Wired Assurance and Marvis Virtual Network Assistant
Ethernet VPNVirtual Extensible LAN (EVPN-VXLAN) to the access layer
End-to-end encryption using Media Access Control Security (MACsec) AES256
IEEE 802.3 bz Multigigabit
IEEE 802.3 bt 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, Junipers 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.
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 802.3 af/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.

Most traditional campus networks have used a single-vendor, chassis-based architecture that worked well for smaller, static campuses with few endpoints. However, this approach is too rigid to support the changing needs of modern campus networks. The EX4400 supports EVPN-VXLAN, extending an end-to-end fabric from campus core to distribution to the access layer.

Virtual Chassis Technology
Junipers Virtual Chassis technology allows multiple interconnected switches to operate as a single, logical unit, enabling users to manage all platforms as one virtual device.

Flow-Based Telemetry
Flow-based telemetry enables flow-level analytics, allowing network administrators to monitor thousands of traffic flows on the EX4400 without burdening the CPU. This improves network security by monitoring, baselining, and detecting flow anomalies. For example, if predefined flow thresholds are breached due to an attack, IP Flow Information Export (IPFIX) alerts can be sent to an external server so the attack can be quickly identified. Network administrators can also automate specific workflows, such as further examining the traffic or quarantining a port, to triage the issue.
