EX4300-48P Juniper EX4300 Series Ethernet Switches is listed by YYST Global for buyers looking for JUNIPER EX4300 Series Ethernet Switches. EX4300-48P is Juniper's 1U 48-port 1GbE PoE+ access switch with four built-in 40GbE QSFP+ ports, a 1100W AC power supply and a 900W-class PoE budget. The listed condition is New Factory Sealed. The reference price is US$ 3,000.00. Contact our sales team to confirm stock, lead time, warranty and configuration before ordering.
EX4300-48P provides 48 built-in 10/100/1000BASE-T access ports, all enabled for PoE+, plus four built-in 40GbE QSFP+ ports. Juniper ships this non-S model with two front-to-back fan modules and one 1100W AC power supply; it is not the component-excluded EX4300-48P-S form.
Juniper's product table gives this model a 900W PoE budget and 30W-per-port PoE+ support. A full forty-eight-device plan must use measured endpoint demand, not simply multiply the maximum per-port figure. Reserve startup margin for phones, cameras and access points, and decide whether a second supply is needed for load sharing, redundancy or a larger available power budget.
The EX4300-48P is rated for 496Gbps switching and 369Mpps wire-speed throughput. Its four QSFP+ ports default to Virtual Chassis ports and can join as many as ten EX4300 members into one logical system. An optional EX-UM-4X4SFP module adds four 1/10GbE SFP/SFP+ uplinks; transceivers and the optional module require separate BOM lines.
Map every copper port to an endpoint class and expected watts, then verify total draw under failover conditions. Test the 1100W supply, both fans, front-to-back airflow, QSFP+ Virtual Chassis links and any optional uplink module. Confirm Junos release support, MACsec requirements and the final optics list before deployment.
