The Juniper EX4400-48P provides resilient campus access for enterprise networks that need dependable connectivity and power for many edge devices. With PoE support and stacking, it helps simplify managed access while keeping offices, wards and depots running smoothly.
As edge access layers absorb more powered devices and tighter service expectations, infrastructure teams need switching that keeps desks, phones, wireless and security endpoints steady without adding unnecessary complexity.
The Juniper EX4400-48P is built as a campus access switch for production networks that need high PoE density in offices, wards, depots and operational support areas. It provides 48×RJ45 1G ports with 2200 W PoE budget, plus 2×QSFP28 uplinks for resilient aggregation.
With stacking support and hot-swappable PSUs, the platform fits environments where change windows are short and continuity matters. It gives network teams a cleaner way to expand access capacity while keeping the switching layer manageable.
The result is a switch that helps standardise powered endpoints on one access platform, simplify closet design, and maintain stable service as device counts rise. It is a sensible fit when gigabit access is enough, but resilience and PoE headroom still matter.
Our team can help you assess the Juniper EX4400-48P for your access layer and map it to your current port, power and uplink requirements.
Juniper EX4400-48P is an enterprise network switching platform for campus and branch environments, designed to provide reliable access connectivity, power delivery, and scalable operations in modern switching deployments.
Enterprise Access Design
The switch provides a campus and branch access layer built around reliable wired connectivity for user, device, and endpoint aggregation.
High-Density Copper Ports
It delivers 48 RJ45 1G ports to support broad access connectivity across typical enterprise edge connections.
Uplink Expansion
Two QSFP28 uplinks provide higher-speed aggregation paths for upstream network integration and capacity growth.
Power Delivery at the Edge
The platform includes PoE capability with a 2200 W budget to support powered network devices on the access layer.
Stackable Architecture
Stacking support helps present multiple switches as a coordinated system for simpler expansion and operational consistency.
Deployment Flexibility
The model supports standardized access-layer rollout patterns that fit distributed enterprise switching environments.
Service Continuity Model
The switching design is intended to maintain dependable edge connectivity while supporting incremental network growth.
If you are planning access-layer refreshes or edge power requirements, our team can help align the EX4400-48P with your campus and branch switching design.

Juniper EX4400-48P is a 48-port PoE access switch for larger campus and site-office environments that need resilient, centrally managed gigabit access. It fits when endpoint density is high, power delivery matters, and multi-gigabit ports would add cost without clear operational value.
In finance office closets, teams need stable PoE access for desks, IP phones, wireless access points and surveillance. The EX4400-48P supports that mix with enough port density for busy floors while keeping the access layer aligned to standard gigabit demand.
Healthcare sites often need many powered endpoints across wards, reception and admin areas, with consistent access control and low disruption. The EX4400-48P helps standardise those spaces on a stronger campus access platform without paying for unnecessary high-bandwidth ports.
Professional services teams usually need one access layer for phones, APs and desk devices across expanding floors. The EX4400-48P reduces closet sprawl and supports frequent moves, adds and changes when standard 1GbE access is the practical choice.
On manufacturing sites, the pressure is often on powering cameras, phones and APs in support offices and control rooms. The EX4400-48P provides resilient PoE access for those endpoints without overbuilding for wireless bandwidth that the area does not need.
Logistics teams need tidy closet-based access for scanners, phones and APs across warehouse offices and dispatch areas. The EX4400-48P gives enough PoE capacity and port count to keep edge clutter down and simplify day-to-day operations.
Our team can help design and deploy Juniper EX4400-48P access for finance, healthcare, professional services, manufacturing and logistics environments, with practical guidance on closet design, endpoint counts, resilience and rollout planning.
