Overview of Ubiquiti UniFi 48-Port Gigabit PoE+ with SFP+ Managed Switch (US-48-500W) | New
The Ubiquiti UniFi 48-Port Gigabit PoE+ with SFP+ Managed Switch (US-48-500W) is an enterprise-grade Layer 2 switch made for demanding SMB, campus and hotel applications as well as high-density UniFi networks. UniFi access points, VoIP phones, IP cameras and other PoE devices may all be powered from a single rackmount platform due to its 48 Gigabit RJ45 ports, strong 802.3af/at PoE+ and 500W power budget. Flexible fiber aggregation and fast access to core switches, routers or storage are made possible by four extra uplink ports: two SFP and two 10G SFP+. The US-48-500W is a potent backbone for scalable, cloud-ready networks because centralized management via the UniFi Network application enables administrators to set up VLANs, QoS, port profiles and monitoring from a single pane of glass.
Key Features of Ubiquiti UniFi 48-Port Gigabit PoE+ with SFP+ Managed Switch
• 48× Gigabit RJ45 PoE+ Ports (802.3af/at) supplies a total of 500W PoE+ power budget, allowing you to power dozens of UniFi APs, IP phones and cameras without separate injectors or midspans.
• 4× Fiber Uplinks (2 SFP + 2 SFP+) includes two 1G SFP and two 10G SFP+ uplink ports for flexible fiber or copper modules, enabling high-bandwidth links to distribution or core switches and servers.
• Managed via UniFi Network Application with centralized, GUI-based configuration and monitoring, create VLANs, apply port profiles, define QoS rules and view real-time traffic and historical statistics across the network.
• Layer 2 Enterprise Switching offers advanced Layer 2 features such as VLAN tagging, link aggregation (LAG), STP/RSTP, port mirroring and robust per-port configuration options suitable for segmented business networks.
• High Performance, Non-Blocking Throughput designed to provide full line-rate forwarding on all 48 Gigabit ports plus uplinks, supporting heavy traffic loads for VoIP, video and data without becoming a bottleneck.
• Rackmount, Robust Design with standard 1U or 2U rackmount metal chassis (model-specific) with integrated cooling, making it suitable for wiring closets, server rooms and data centers.
Benefits of Ubiquiti UniFi 48-Port Gigabit PoE+ with SFP+ Managed Switch
🗹 Build a PoE-First Campus or Office that power and connect nearly all edge devices—Wi-Fi access points, security cameras and phones—from a single switch, simplifying cabling and lowering installation costs.
🗹 Scale and Segment Your Network Easily that 48 ports plus SFP/SFP+ uplinks give you ample headroom to grow, while VLANs and link aggregation let you segment traffic and increase backbone bandwidth as needs evolve.
🗹 Improve Application Performance that intelligent QoS and non-blocking switching help prioritize real-time traffic like voice and video, supporting smooth calls and streaming even during heavy usage.
🗹 Simplify Management for IT Team that UniFi’s centralized dashboard reduces hands-on configuration time, provides quick visibility into port status and client behavior, and streamlines troubleshooting across sites.
🗹 Future-Ready Investment that 10G SFP+ uplinks, PoE+ support, and tight integration with the broader UniFi ecosystem make the US-48-500W a long-term, flexible foundation for modern IP networks.
