Juniper Networks EX4000-48T 48-Port Gigabit PoE+ Switch with 4x 10G SFP+ Uplinks

As enterprise networks grow, the demand for reliable, high-performance access switching with Power over Ethernet becomes critical. The Juniper Networks EX4000-48T addresses this need by delivering 48 Gigabit Ethernet ports with PoE+ support and four 10GbE SFP+ uplinks in a compact 1U form factor. This switch is engineered to power and connect a wide range of devices—from IP phones and wireless access points to surveillance cameras—while providing the throughput and management features required for modern campus and branch deployments.

Who is it for

This switch is ideal for IT administrators and network engineers in mid-sized to large enterprises who need a scalable, secure, and easy-to-manage access layer solution. It suits organizations deploying high-density PoE devices, such as schools, hospitals, retail chains, and corporate offices, where reliability and simplified operations are paramount.

Tips

To maximize uptime, consider deploying redundant power supplies and use Virtual Chassis to simplify management across multiple switches. For high-density PoE deployments, ensure your power budget is planned to avoid exceeding the 740W limit. Use the SFP+ uplinks to connect to aggregation switches or core networks for optimal performance.
