The Ubiquiti UniFi Switch Pro 48 (USW-Pro-48) is designed to serve as a high-density aggregation and access switch for enterprise and advanced professional networks. Housed in a 1U rack-mount form factor, the switch features a robust SGCC steel enclosure engineered for durability in data center and wiring-closet environments. With compact dimensions of 442 × 285 × 44 mm, it fits seamlessly into standard racks with supported depths from 400 to 1200 mm, ensuring compatibility across a wide range of installations. Connectivity is a defining strength of the USW-Pro-48. It provides 48 Gigabit Ethernet RJ45 ports supporting 10M/100M/1G speeds, making it ideal for connecting large numbers of endpoints such as workstations, access points, IP phones, cameras, and AV devices.

For high-speed uplinks and backbone connectivity, the switch includes four 10G SFP+ ports with backward compatibility for 1G SFP, enabling flexible fiber or DAC connections to core switches or servers. Built for performance-intensive environments, the switch delivers a switching capacity of 176 Gbps and a total non-blocking throughput of 88 Gbps, ensuring simultaneous full-speed communication across all ports without congestion. A forwarding rate of 131 million packets per second allows the USW-Pro-48 to handle large volumes of small packets efficiently, which is critical in modern enterprise, VoIP, and video-rich networks. Supporting up to 1,000 VLANs and a MAC address table size of 16,000 entries, the switch is well suited for segmented networks, multi-tenant deployments, and complex enterprise topologies. These capabilities make the USW-Pro-48 a powerful foundation for scalable, high-performance network architectures.

The UniFi Switch Pro 48 delivers extensive Layer 2 and Layer 3 functionality, allowing it to operate not only as a high-capacity switch, but also as an intelligent routing and control element within local networks. With full Layer 3 support, the switch enables inter-VLAN routing, reducing dependency on external routers and improving latency for internal traffic flows. Integrated static routing capabilities support up to 1,000 IPv4 routes, while the Layer 3 table accommodates 4,000 ARP entries, ensuring stable performance in large IP environments. For automated network services, the USW-Pro-48 includes a DHCP server for local networks as well as DHCP relay, simplifying IP address management across segmented infrastructures. On the security and access-control side, the switch supports IPv4 access control lists (up to 128 rules) and MAC-based ACLs (128 entries), enabling granular traffic filtering and network isolation policies.

Layer 2 capabilities are equally comprehensive. LACP port aggregation allows multiple physical links to be combined for higher throughput and redundancy, while STP and RSTP protect the network from loops. Advanced multicast handling is provided through IGMP snooping and configurable IGMP features such as querier, fast leave, and router port, which are especially valuable in IPTV and AV-over-IP deployments. The switch supports a wide range of enterprise and professional AV features, including QoS with DSCP, Voice VLAN, LLDP-MED, and Pro AV profiles for platforms such as Dante, Q-SYS, NDI, SDVoE, Shure, AES67, and Crestron. Additional controls—such as port isolation, mirroring, storm control, jumbo frames, rate limiting, and MAC or IP-based restrictions—provide administrators with precise control over traffic behavior and endpoint access.

The UniFi Switch Pro 48 is engineered for continuous, reliable operation in demanding enterprise environments. It features an internal AC/DC power supply rated at 60W, operating across a wide 100–240V AC, 50/60 Hz input range. For enhanced availability, the switch includes a DC power backup input compatible with USP RPS, allowing power redundancy and minimizing downtime in critical network deployments. The maximum power consumption of 60W ensures energy-efficient operation without compromising performance. Thermal and environmental resilience are key design priorities. The switch dissipates 204.7 BTU/hr of heat and is rated for operation in ambient temperatures from -5 to 40°C, with 10–90% non-condensing humidity, making it suitable for a wide variety of installation locations. Integrated ESD protection safeguards the hardware against electrical discharge, with ratings of ±16 kV air and ±12 kV contact, enhancing long-term reliability.

For management and monitoring, the USW-Pro-48 integrates seamlessly into the UniFi Network Controller, requiring UniFi Network version 5.12.11 or later. Management access is available via Ethernet, and real-time system information can be viewed directly on the front panel through a 1.3-inch touchscreen LCM display, simplifying diagnostics and port status checks during installation and maintenance. From a compliance and security standpoint, the switch is fully NDAA compliant and certified for use in global markets, holding CE, FCC, IC, and Anatel certifications. Combined with its steel mounting hardware, secure rack installation, and enterprise-grade software features, the UniFi Switch Pro 48 stands as a dependable, scalable, and professionally engineered solution for modern networks.
