Description

The Juniper EX4400‑48MP is a robust multigigabit campus access switch engineered for high‑performance enterprise networks that demand flexible speeds, rich PoE capabilities, and modern fabric support. As part of the EX4400 line, this model runs Juniper’s Junos OS and integrates seamlessly with Juniper Mist Wired Assurance for cloud‑managed deployment, AI insights, and simplified operations.

This 1 RU fixed‑configuration switch features a versatile mix of multigigabit ports: 12× capable of 100 Mbps/1 GbE/2.5 GbE/5 GbE/10 GbE and 36× capable of 100 Mbps/1 GbE/2.5 GbE, enabling high‑speed access for Wi‑Fi 6/6E/7 access points, dense client devices, and aggregated uplinks. All RJ‑45 ports support IEEE 802.3bt PoE/PoE+ (PoE‑bt) up to 90 W per port, making this switch ideal for powering high‑demand endpoints such as multi‑radio wireless APs, PTZ cameras, and IoT devices.

For upstream and stacking connectivity, the EX4400‑48MP includes 2× 100 GbE QSFP28 ports, which can be used for high‑capacity uplinks to distribution/core switches or for Virtual Chassis interconnects. Optional extension modules (e.g., additional 4×10 GbE or 4×25 GbE) further enhance flexibility for diverse network topologies.

Security and performance features such as MACsec AES‑256 encryption, enriched telemetry, EVPN‑VXLAN fabric support, and Virtual Chassis clustering up to 10 units make the EX4400‑48MP a future‑ready choice for flexible and secure enterprise campus networks.
