Enterprise-Grade Performance
The US-48 delivers 104 Gbps switching capacity and 52 Gbps total non-blocking throughput, ensuring all 48 ports can operate simultaneously at full Gigabit line rate without packet loss. The 77.376 Mpps forwarding rate handles heavy network traffic with ease, making it ideal for demanding applications like IP surveillance systems, digital signage networks, AV over IP installations, and multi-device office environments.
UniFi Ecosystem Integration
Seamlessly integrate the US-48 into your UniFi network ecosystem alongside UniFi access points, routers, security cameras, and VoIP phones. The UniFi Network Controller provides a single pane of glass to monitor and configure your entire network, with real-time statistics, topology mapping, and Deep Packet Inspection (DPI) for application-aware traffic analysis.
Advanced Layer 2 Switching Features
- VLAN support (up to 1,000 VLANs) for network segmentation
- Link Aggregation (LACP) for increased bandwidth and redundancy
- Spanning Tree Protocol (STP/RSTP) for loop prevention
- IGMP snooping for optimized multicast traffic (ideal for video streaming and IPTV)
- 802.1X authentication for secure network access control
- Port mirroring for network monitoring and troubleshooting
- QoS (Quality of Service) for traffic prioritization
- DHCP snooping and MAC address filtering for enhanced security
Flexible Connectivity Options
The US-48 offers versatile connectivity with 48 auto-sensing RJ45 Gigabit ports (10/100/1000 Mbps), 2 x 1G SFP fiber ports for medium-distance uplinks, and 2 x 10G SFP+ ports for high-speed fiber backbone connections to your core network or NAS devices. The included 1.3-inch touchscreen LCD provides at-a-glance status information and quick diagnostics without requiring computer access.
