Juniper EX4400 Series

IT teams needing steadier control at the edge use Juniper EX4400 Series to keep wired and wireless access aligned across offices, clinics and distributed sites. It gives a managed campus access layer for powered devices, user access and branch connectivity, with Juniper Mist AI and EVPN-VXLAN support helping standardise operations as demand grows.

It suits compact closets, larger access rooms and fibre-fed edge zones where consistent uptime, local control and less troubleshooting matter. The range supports multi-gigabit and 1GbE access, fibre aggregation and virtual chassis scale, helping maintain service continuity, avoid bottlenecks and keep endpoint growth under one management model.

Juniper EX4400 Quick Specs & Key Features

Multi-gigabit PoE access: Multi-gigabit and 1GbE copper options with high PoE capacity support Wi-Fi 6/6E/7 access points, phones and IoT devices from one closet, so dense edge spaces can expand wireless capacity without replacing the access layer.
EVPN-VXLAN campus fabric: EVPN-VXLAN integration provides a policy-aware campus fabric for consistent segmentation across distributed buildings, so enterprise networks gain simpler scaling and tighter control as sites grow.
Mist AI operations: Mist AI cloud management adds visibility, automation and troubleshooting across the range, so IT teams can standardise deployment and reduce operational overhead in branch, office and clinical environments.

Virtual Chassis scaling: High-speed Virtual Chassis interconnects let multiple switches operate as one managed system, so closets and distribution points can be expanded with less complexity and lower administrative effort.
Fibre access flexibility: Fibre-focused 10GbE SFP+ and 1GbE SFP options support long runs, electrical isolation and compact aggregation roles, so sites can replace copper where distance or interference would otherwise limit design choices.
Enterprise access resilience: Junos-based switching and high-availability campus features support stable day-to-day service for secure branches, healthcare spaces and high-value offices, so endpoint access remains available under operational pressure.

Juniper EX4400 Deployment Scenarios and Industries

Data Centres

Data-centre teams need compact fibre access or aggregation for server rooms and edge racks where 10GbE links are enough, but a full leaf switch would be excessive. The EX4400 series supports fibre-based designs, central management and campus fabric integration for smaller compute and storage environments.

Media & Entertainment

Media teams need faster movement between edit workstations, shared storage and production systems, with less delay than 1GbE access can provide. The EX4400 series supports fibre-rich edge designs for studios and suites that rely on 10GbE connectivity and consistent network control.

Hotels and Hospitality

Hotels need access switching that can support guest Wi-Fi, conference areas and many powered endpoints without overbuilding small closets. The EX4400 series fits these spaces with PoE capacity, multi-gigabit options for higher-demand wireless, and managed campus features.

Professional Services

Professional services firms need dependable access for phones, APs, meeting rooms and shared work areas, often across older or space-limited offices. The EX4400 series supports standard PoE, fibre access and cloud-managed operations so distributed teams can keep day-to-day service consistent.

Healthcare

Healthcare teams need resilient access in clinical areas, admin spaces and dispersed buildings where powered devices, wireless coverage and cable reach all matter. The EX4400 series supports higher PoE demand, fibre options and campus fabric designs for dependable clinical connectivity.
