Ubiquiti USW-ENTERPRISE-48-POE UniFi Network Switch

Ubiquiti USW-ENTERPRISE-48-POE UniFi Network Switch

Overview

The Ubiquiti USW-ENTERPRISE-48-POE is a high-performance, rack-mounted Layer 3 managed switch designed for enterprise and mid-market network deployments. With 48 ports of 2.5G connectivity plus four 10G SFP+ uplinks, this switch delivers 160 Gbps non-blocking switching capacity and 238 Mpps forwarding rate, making it suitable for dense access-layer deployments where PoE power and uplink bandwidth are critical. The unit integrates seamlessly into UniFi network ecosystems and supports standard IPv4/IPv6 routing and VLAN segmentation across 1,000 VLANs.

Key Features

The USW-ENTERPRISE-48-POE provides 720W of PoE output budget, enabling deployment of 40–50 standard PoE cameras or powered devices per switch without auxiliary power injection. All 48 ports operate at 2.5G, eliminating the bandwidth bottlenecks common in mixed 1G/multi-gig environments. The four 10G SFP+ uplinks support stacking, inter-switch trunking, or core aggregation without blocking. Power consumption is modest at 150W base load (excluding PoE draw), with maximum system draw of 870W at full PoE output when operating from a universal 100–240V AC supply. The switch occupies a standard 1U form factor and weighs 6.2 kg, simplifying integration into existing rack infrastructures. NDAA compliance and certifications (CE, FCC, IC, Anatel) confirm suitability for regulated deployments.

Deployment Scenarios

This switch is well-suited for campus or enterprise branch locations requiring high-density PoE access. Typical deployments include IP camera farms (48-port capacity allows a single switch to power a mid-sized surveillance array), WiFi 6/6E access point aggregation, and mixed IoT sensor networks. The MPN USW-ENTERPRISE-48-POE scales horizontally across multiple switches via the 10G uplinks, enabling non-blocking fabric designs. For data-center edge or colocation environments with power constraints, the internal AC/DC supply and low idle power draw reduce auxiliary cooling and PDU overhead.

Network Integration

Management occurs via Ethernet and integrates with Ubiquiti's UniFi ecosystem, allowing centralized configuration, monitoring, and guest portal deployment through UniFi Network application. The switch supports 802.1Q VLAN tagging, Link Aggregation Control Protocol (LACP), Spanning Tree Protocol (RSTP/MSTP), and static routing, making it compatible with standard enterprise network designs. Jumbo frame support accommodates high-throughput storage and virtualization traffic. No controller is required for basic switching, though adoption into UniFi dramatically simplifies multi-switch management.

Installation Notes

The USW-ENTERPRISE-48-POE mounts in standard 19-inch racks using included SGCC steel brackets. Operating temperature range is –5°C to 40°C, suitable for data center and outdoor equipment shelters with standard climate control. All ports use standard RJ45 connectors; SFP+ uplinks accept passive DAC or active optical modules. During deployment, verify PoE budget allocation, as simultaneous power draw from all 48 ports plus uplink traffic may approach thermal limits in ambient temperatures above 35°C.

Marty Allison, Infrastructure Architect

The USW-ENTERPRISE-48-POE strikes a practical balance between port density, PoE capacity, and cost. For integrators building mid-market security networks, the 720W PoE budget and all-2.5G fabric eliminate the artificial bottlenecks you hit with mixed-speed switches. The four 10G uplinks are genuinely non-blocking, not marketing window dressing. If you're deploying 30+ cameras plus access points, this unit pays for itself in simplified cabling and single-vendor management. One note: confirm your upstream gear supports 2.5G or use DAC adapters—some older core switches still top out at 1G, and you'd be starving the access tier unnecessarily.
