Cisco SG550X-48P 48-Port PoE Switch Refurbished | Layer 3, Stackable — SG550X-48P-K9NA-RF

Refresh the access layer with a switch designed for dense endpoint power and straightforward network segmentation. The Cisco SG550X-48P delivers 48 PoE-enabled Gigabit ports in a manageable, stackable platform, making it a practical fit for office floors, branch closets, and distributed campus wiring rooms. Layer 3 support gives network teams more control over routing at the edge, while VLAN support helps separate voice, data, guest, and surveillance traffic cleanly. The modular design and optical fiber/twisted pair connectivity options make it easier to align the switch with existing uplink standards and migration plans. As a refurbished unit, it can be a smart way to extend the life of a proven access architecture while preserving budget for higher-value upgrades elsewhere. Choose this model when you need a mature switching platform with enough PoE density for modern endpoint counts, plus the flexibility to fit into established Cisco environments. It is especially useful where procurement wants lower acquisition cost, but operations still expect stable behavior and familiar management patterns.
