Guide price: Price range: £2,016.10 through £3,837.00 Ex. VAT

Product Overview

The Juniper EX4100-48P is a high-density enterprise access switch providing 48 x 10/100/1000 BASE-T ports with PoE+ support, ideal for powering edge devices such as wireless access points, IP phones and cameras directly from the switch. It offers a flexible uplink mix of 4 x 1/10 GbE SFP/SFP+ plus 4 x 10/25 GbE Virtual Chassis/uplink ports (optics sold separately), and runs Junos OS for consistent Layer 2/Layer 3 services and fabric integration. The model supports EVPN-VXLAN campus fabrics and Virtual Chassis scaling for unified management across up to ten switches.

Ideal deployment / environment:
The EX4100-48P is suited to enterprise access layer deployments requiring high port density and robust PoE+ power delivery. Its 48 PoE+ ports support powered devices without additional injectors, while 10 GbE and 25 GbE uplink options provide efficient data aggregation into distribution or core layers. Virtual Chassis and EVPN-VXLAN support enables scalable campus fabrics and simplified management for distributed access switches, making this model appropriate for campus networks, building wiring closets and branch offices where unified access, consistent policy enforcement and resilient data delivery are priorities.
