Ubiquiti USW-PRO-XG-48 UniFi Network Switch

Ubiquiti USW-PRO-XG-48 UniFi Network Switch

Overview

The Ubiquiti USW-PRO-XG-48 is a 1U rack-mount switch designed for high-density data center and enterprise campus deployments requiring multi-speed Ethernet connectivity. This 48-port switch delivers 920 Gbps switching capacity with 460 Gbps non-blocking throughput and a 684 Mpps forwarding rate, supporting mixed speed requirements across modern infrastructure environments. The USW-PRO-XG-48 integrates into UniFi Network management, enabling centralized control and monitoring alongside other UniFi infrastructure components.

Key Features

The switch provides 32 ports of 10GbE connectivity for high-speed backbone and server uplinks, 16 ports of 2.5GbE for mid-tier access devices, and four 25G SFP28 ports for direct fiber connections. This mixed-port architecture accommodates gradual network evolution without requiring wholesale replacement. The device supports up to 1,000 VLANs for network segmentation and isolation. With a maximum power consumption of 250W and an internal 300W AC/DC power supply accepting universal input (100–240V AC, 50/60 Hz), deployment is straightforward in standard rack environments operating between -5 and 40°C. The SGCC steel enclosure and mounting brackets provide durability, with the chassis weighing 7.5 kg.

Deployment Scenarios

The Ubiquiti USW-PRO-XG-48 suits environments where multi-speed port support reduces hardware costs. Education institutions can use 10GbE uplinks between buildings while maintaining 2.5GbE connections to wireless access points and edge devices. Enterprise data centers benefit from 10GbE server connections and 25G fiber uplinks to aggregation layers. Service providers and managed service operators can deploy the switch as a leaf-layer access point, leveraging UniFi management for rapid provisioning and troubleshooting across multiple sites.

Network Integration

The switch integrates with UniFi Network application for unified dashboard visibility, configuration, and firmware management. Ethernet-based management allows out-of-band or in-band control depending on network design. VLANs enable traffic separation for security and performance isolation. The four 25G SFP28 ports support both active optics and direct-attach copper cables, allowing flexible connections to core infrastructure or redundant uplinks.

Installation Notes

The USW-PRO-XG-48 requires standard 19-inch rack space and standard AC power. Passive cooling operates without fans, reducing acoustic noise in equipment rooms. CE, FCC, IC, and Anatel (06464-25-08356) certifications confirm compliance with regulatory requirements. NDAA compliance is confirmed for U.S. government and defense sector deployments.

Marty Allison, Infrastructure Architect

"The port mix on the USW-PRO-XG-48 reflects real-world heterogeneous networks. You're not forced into all-10G or all-2.5G; you scale cost-effectively. The 920 Gbps switching capacity and non-blocking throughput handle bursty workloads without bottlenecking. In UniFi environments with 50+ sites, centralized firmware and config updates save significant operational time. The 25G SFP28 uplinks are future-proofed for growth without board replacement."
