Juniper EX4300-48P — 48-Port PoE+ Gigabit Switch

Enterprise-class 1U access switch with 48 Gigabit PoE+ ports, a 950 W power budget, four built-in 40GbE QSFP+ uplinks and Virtual Chassis stacking. Runs Junos OS with full Layer 2/Layer 3 and is backed by a 12-month Reboot IT warranty.

Key Benefits

• 48 ports of PoE+: Power IP phones, wireless access points, cameras and more directly from the switch, with a generous 950 W power budget.
• High-speed 40GbE uplinks: Four built-in QSFP+ ports give ample bandwidth back to the core and eliminate uplink bottlenecks.
• Virtual Chassis stacking: Interconnect up to 10 switches and manage them as a single logical device — simpler operations, fewer touch points.
• Layer 2 and Layer 3: Junos OS delivers advanced switching and routing in one box, so you can segment and route without extra hardware.
• Carrier-class resilience: Hot-swappable redundant power supplies and fans keep the switch running through component failures and maintenance.
• Sustainable choice: Certified refurbished enterprise hardware at a fraction of new cost, keeping quality equipment out of landfill.

Performance in Use

The EX4300-48P is built for the wiring closet — campus access layers, office floors and mid-size data centres where a lot of powered devices meet the network. All 48 Gigabit ports support 802.3at PoE+, and the 950 W budget comfortably drives dense deployments of Wi-Fi access points, VoIP handsets and IP cameras without separate power injectors.

Four 40GbE QSFP+ ports handle high-bandwidth uplinks or double as Virtual Chassis links. With Virtual Chassis you can join up to ten EX4300 units into one logical switch, managed from a single address and configuration — dramatically simplifying day-to-day operations as the deployment grows.

Running Juniper's Junos OS, the switch offers robust Layer 2 features plus Layer 3 routing, so you can build segmented, resilient networks in a single device. Redundant, hot-swappable power supplies and fan modules mean maintenance and component swaps happen without taking the switch offline — the kind of reliability production networks depend on.
