Ubiquiti UniFi Switch Standard 48 PoE

The Ubiquiti UniFi Switch Pro 48 (USW-Pro-48) is a powerful enterprise-class PoE switch designed for modern business networks that require both high port density and integrated power delivery. Built in a rack-mountable 1U form factor, the switch fits seamlessly into standard network racks with supported depths from 400 to 1200 mm, while its compact 442 × 285 × 44 mm dimensions help conserve valuable rack space. The enclosure and mounting hardware are constructed from durable SGCC steel, ensuring long-term reliability in professional IT environments. The switch provides 48 Gigabit Ethernet RJ45 ports, of which 32 ports support PoE+, allowing direct power delivery to access points, IP cameras, VoIP phones, and other powered devices without the need for external injectors. Each PoE port supports up to 15.4 W (PoE) or 32 W (PoE+), with a total PoE power budget of 195 W, enabling flexible power distribution across multiple endpoints. This makes the USW-Pro-48 an ideal choice for dense PoE deployments in offices, campuses, retail locations, and hospitality environments.

For uplink and aggregation connectivity, the switch is equipped with four 1G SFP ports, providing fiber or DAC connectivity to upstream switches, servers, or network cores. This combination of copper and fiber interfaces allows network architects to design scalable and resilient topologies without additional hardware. With a switching capacity of 104 Gbps, total non-blocking throughput of 52 Gbps, and a forwarding rate of 77 million packets per second, the USW-Pro-48 ensures smooth, congestion-free traffic flow even under heavy loads. Support for up to 1,000 VLANs and a MAC address table size of 16,000 entries makes the switch well suited for segmented enterprise networks, multi-department infrastructures, and growing organizations.

The UniFi Switch Pro 48 offers a comprehensive set of advanced Layer 2 features, providing administrators with precise control over traffic behavior, security, and performance across the network. Support for LACP port aggregation enables multiple physical links to be combined into a single logical interface, increasing bandwidth and providing redundancy for critical connections. STP and RSTP protocols help prevent switching loops and ensure fast network convergence in complex topologies. For multicast-heavy environments, such as IPTV and AV-over-IP deployments, the switch includes advanced IGMP configuration options, including IGMP Snooping, Querier, Fast Leave, and Router Port support. These features optimize multicast traffic delivery, reducing unnecessary load on network links and connected devices.

Security is addressed through a broad range of control mechanisms. The switch supports 802.1X port-based authentication, MAC-based ACLs, MAC address blocking, and MAC-based port restrictions, allowing administrators to tightly regulate device access. Additional protections such as DHCP Snooping and Guarding, IP-based ACLs, and network isolation help defend against common Layer 2 attacks and unauthorized traffic. Traffic management features include QoS support with Voice VLAN, LLDP-MED for automated endpoint provisioning, egress rate limiting, flow control, and storm control for broadcast and multicast suppression. Administrators can also enable jumbo frames, configure port isolation, perform port mirroring for diagnostics, and apply virtual network overrides to fine-tune network behavior. Together, these Layer 2 capabilities make the USW-Pro-48 a highly adaptable switch suitable for enterprise, education, healthcare, and professional AV networks.

The UniFi Switch Pro 48 is engineered for stable, long-term operation in demanding professional environments. It features an internal AC/DC power supply rated at 240 W, operating from a universal 100–240 V AC input at 50/60 Hz, ensuring compatibility with electrical standards worldwide. When excluding PoE output, the switch consumes up to 45 W, while maximum total power consumption reaches 240 W when PoE delivery is fully utilized. Thermal efficiency is optimized for rack installations, with heat dissipation of 153.5 BTU/hr (excluding PoE output), supporting reliable operation without excessive cooling requirements. The switch is protected against electrical disturbances through ESD protection rated at ±16 kV (air discharge) and ±12 kV (contact discharge), reducing the risk of hardware damage in electrically noisy environments.

Management and monitoring are handled through the UniFi Network application, requiring UniFi Network version 7.2.94 or later. Administrators can manage the switch centrally via Ethernet, while a built-in 1.3-inch touchscreen LCM display on the front panel provides real-time status information, port activity, and device health, simplifying installation and troubleshooting. From a compliance perspective, the USW-Pro-48 is fully NDAA compliant and certified for international deployment, including CE, FCC, IC, and Anatel certifications. Combined with its steel construction, professional-grade power design, and advanced software ecosystem, the UniFi Switch Pro 48 delivers a reliable and scalable foundation for modern PoE-enabled enterprise networks.
