Ubiquiti USW-PRO-48 UniFi Network Switch

Ubiquiti USW-PRO-48 UniFi Network Switch

Overview

The Ubiquiti USW-PRO-48 is a rack-mountable gigabit switch engineered for medium to large UniFi network deployments. Built with 48 ports operating at 10/100/1000 Mbps, this switch delivers 176 Gbps of switching capacity and a forwarding rate of 131 Mpps, making it suitable for enterprise branch offices, data centers, and high-density access environments. The unit measures 442 x 285 x 44 mm and weighs 4 kg without mounting brackets, featuring an SGCC steel enclosure designed for standard 19-inch rack installations. Power consumption is minimal at just 60W via universal AC input (100–240V, 50/60 Hz) with an integrated internal AC/DC supply.

Key Features

The USW-PRO-48 integrates seamlessly into UniFi ecosystems, managed entirely through Ethernet connectivity without requiring dedicated serial or console access. All 48 gigabit ports deliver consistent wire-speed performance across the platform. The switch operates reliably in temperature ranges from -5 to 40°C, supporting both controlled data center environments and less climate-regulated installation spaces. NDAA compliance and certifications including CE, FCC, IC, and Anatel approval (00469-21-08356) ensure regulatory alignment for government and enterprise procurement requirements.

Deployment Scenarios

The Ubiquiti USW-PRO-48 functions as a core or distribution-layer switch for organizations consolidating network access across multiple floors or facilities. Common deployments include campus networks where the switch serves as a central aggregation point for access switches, IP camera surveillance systems requiring high port density, and virtualized infrastructure supporting UniFi access points and controller redundancy. The 176 Gbps backplane accommodates simultaneous multi-gigabit traffic without bottlenecking typical enterprise workloads.

Network Integration

Integration with UniFi controllers is automatic upon connection to a network segment where a controller resides. No configuration scripts or third-party management platforms are required. The switch supports standard Ethernet management and integrates with UniFi's centralized dashboard for VLAN configuration, port mirroring, and traffic monitoring. Operators can adopt the USW-PRO-48 into existing UniFi deployments alongside access points, gateways, and security appliances within a single management pane.

Installation Notes

Installation requires standard 19-inch rack space and two rack units of vertical clearance. SGCC steel mounting brackets support tool-free or hardware-secured installation. The internal power supply accepts 100–240V AC, eliminating the need for external power adapters. Ensure adequate ventilation around intake and exhaust areas despite the low 60W power profile. Cabling uses standard RJ45 connectors; Cat5e or higher cabling is recommended for optimal performance across all port distances.

Marty Allison, Infrastructure Architect

"The USW-PRO-48 represents a straightforward, no-nonsense access and distribution switch for organizations already committed to the UniFi ecosystem. It delivers the port density and switching capacity required for most mid-market deployments without overengineering. The MPN USW-PRO-48 identifies a unit that balances cost-effectiveness with reliability—neither overspecced nor underpowered for typical gigabit workloads. If you need PoE injection or multi-gig uplinks, look elsewhere; for standard Ethernet aggregation in a UniFi environment, this switch executes its role competently."
