Ubiquiti UniFi 48 PoE Switch | 48-Port Gigabit Rackmount Switch

Ubiquiti UniFi 48 PoE Gigabit Switch (USW-48-PoE)

The Ubiquiti UniFi 48 PoE is a fully managed Layer 2 switch designed to provide expansive port density and reliable power distribution across enterprise, commercial, and educational networks. This 1U rack-mountable unit allows network administrators to consolidate a massive array of network devices—such as IP surveillance cameras, wireless access points, VoIP phone systems, and desktop workstations—into a single central patch frame.

With a total non-blocking switching throughput of 52 Gbps, the switch handles high-volume traffic trunking across all forty-eight copper interfaces simultaneously without data congestion.

High-Density Port Configuration & Uplinks

• Flexible PoE Allocation: Features forty-eight Gigabit RJ45 ports in total. Ports 1 to 32 support auto-sensing 802.3at PoE+ to deliver both high-speed data and electricity over a single network cable, while ports 33 to 48 function as standard non-PoE Gigabit connections for computers, printers, and local network drives.

• 1G Fibre SFP Uplinks: Equipped with four dedicated 1G SFP ports. These interfaces handle high-speed fibre backhaul lines to your core routing hardware, allowing you to daisy-chain multiple switches together across separate floors or network racks.

• Whisper-Quiet Thermal Management: Built with an advanced internal cooling chassis that regulates temperature dynamically. The fans operate at minimal speeds under normal loads, making the switch exceptionally quiet for deployment in open-plan offices or retail environments where dedicated server rooms are unavailable.

Power Over Ethernet Capacity

The USW-48-PoE features a dependable internal power supply system that leaves a 195W dedicated PoE power budget solely for downstream hardware deployment.

• Max. PoE+ Output Per Port: Up to 32W

• Intelligent Overcurrent Protection: Automatically tracks the electrical draw of attached devices via the UniFi network controller, preventing system damage by managing power delivery thresholds dynamically.

Centralised Control & Diagnostics

• 1.3" LCM Colour Touchscreen: The front-panel liquid crystal display gives network engineers instantaneous hardware readouts, including real-time power consumption figures, link speeds, data throughput tracking, and system warnings.

• Unified Management Platform: Monitored and configured entirely within the UniFi Network application. From this dashboard, you can build separate guest VLANs, manage port isolated safety profiles, configure spanning tree protocols, and power-cycle frozen devices remotely.
