Ubiquiti UniFi USW-48 Switch

The Ubiquiti UniFi USW-48 is a high-capacity, Layer 2 Gigabit managed switch designed for versatile enterprise deployments. With 48 RJ45 Gigabit Ethernet ports and 4 SFP ports for fiber uplinks, this switch offers extensive connectivity options for growing networks that require performance, reliability, and simplified management. Whether deployed in business environments, education institutions, or multi-floor commercial buildings, the USW-48 provides the scalability and control needed to support wired infrastructure for everything from client devices to IP surveillance and VoIP.

One of the USW-48’s key features is its completely silent, fanless design. The passive cooling system ensures it operates quietly, making it suitable for noise-sensitive environments such as offices, classrooms, or even open meeting areas. Despite its lack of active cooling, the switch maintains thermal efficiency through its well-ventilated chassis and low-power component design.

The USW-48 is rack-mountable and fits easily into standard 1U slots, making it ideal for data cabinets or server rooms. Its SFP uplink ports allow for high-speed fiber connections to aggregation switches or core routers, enabling flexible network expansion without bottlenecks. The Gigabit ports can connect to workstations, UniFi access points, printers, IP phones, or other LAN devices, ensuring reliable wired performance across all endpoints.

Fully integrated with the UniFi Network Controller, the USW-48 provides powerful configuration tools for VLANs, port monitoring, link aggregation, and firmware updates. Administrators can manage large fleets of UniFi switches, access points, and gateways from a single centralized dashboard. The controller interface offers live network mapping, traffic analytics, and remote troubleshooting features that reduce complexity and speed up maintenance.

Although the USW-48 does not support PoE, it complements PoE switches in larger environments by handling non-powered devices or offloading distribution ports. This approach offers a cost-effective way to build out the wired side of a hybrid network that balances PoE requirements and pure data transport needs.

In summary, the UniFi USW-48 is a dependable, high-density switch that combines fanless operation, robust Layer 2 functionality, and seamless UniFi Controller management. It’s ideal for standard enterprise switching roles where reliability, quiet operation, and manageability matter. Built to scale and built to last, it’s an essential backbone component for UniFi-based infrastructure.
