Juniper EX4400-48MP – Multigigabit PoE+ Ethernet Switch

Guide price: Price range: £2,937.50 through £3,739.00 Ex. VAT

Product Overview

The Juniper EX4400-48MP is a high-performance, multigigabit access switch optimised for enterprise and campus edge deployments that need both advanced wired speeds and substantial Power over Ethernet support. It provides a mix of 12 x 100 Mb/1 Gb/2.5 Gb/5 Gb/10 GbE multigigabit PoE++ ports and 36 x 100 Mb/1 Gb/2.5 GbE PoE++ ports, delivering up to 90 W per port in line with IEEE 802.3bt. With flexible uplink/stacking options and Junos OS for rich Layer 2/Layer 3 services, EVPN-VXLAN fabric support and cloud-ready management, the EX4400-48MP meets the needs of modern, high-density access networks.

Ideal deployment / environment:
The EX4400-48MP is well suited to enterprise access layers where both high-speed multigigabit connectivity and strong PoE++ power delivery are needed to support dense device populationsósuch as Wi-Fi 6/7 access points, high-power IoT devices, VoIP phones and security cameras. Its substantial PoE budget and flexible uplinks simplify aggregation into distribution or core layers, while EVPN-VXLAN and Virtual Chassis enable scalable fabric designs with unified management. This model aligns with campus networks, large building access points and distributed enterprise environments that demand rich telemetry, resilient forwarding and cloud-ready operations.
