Ubiquiti USW-16-POE UniFi Network Switch

Ubiquiti USW-16-POE UniFi Network Switch

Overview

The Ubiquiti USW-16-POE is a compact 1U rack-mount switch designed for small to mid-scale UniFi deployments requiring integrated Power over Ethernet (PoE) delivery. With 16 Gigabit RJ45 ports plus 2 SFP uplinks, this switch combines wired access density with sufficient backhaul capacity for distributed access point and IP camera installations. The USW-16-POE delivers 36 Gbps switching capacity and 18 Gbps non-blocking throughput, supporting forwarding rates of 27 Mpps across a 42W PoE power budget. Universal AC input (100–240V, 50/60 Hz) and an internal 60W power supply enable flexible deployment in standard equipment racks or wall-mounted cabinets.

Key Features

The USW-16-POE supports up to 1,000 VLANs for network segmentation and traffic isolation, essential for multi-tenant and security-focused infrastructure. Its SGCC steel enclosure and mounting brackets provide durability in both climate-controlled and field environments, with an operating temperature range of −5 to 40° C. The switch consumes 18W in idle operation (excluding PoE output), making it power-efficient for always-on deployments. Management occurs entirely over Ethernet, with no console port required—integration into UniFi Controller-managed networks is immediate upon power-on. The device carries CE, FCC, IC, and Anatel certifications, along with NDAA compliance for federal and defense sector procurement.

Deployment Scenarios

Typical deployments include small office access networks, remote site consolidation points, and edge switching for distributed camera systems. The 42W PoE budget supports 8–10 standard access points or a mixed load of cameras and wireless clients. In campus or multi-building setups, the SFP uplinks connect to fiber backbone switches or aggregation points, reducing cable runs over long distances. The USW-16-POE also suits IoT sensor networks and building automation where PoE endpoints are co-located with Ethernet infrastructure.

Network Integration

UniFi Controller automatically discovers and provisions the USW-16-POE upon connection to the management network. Its non-blocking throughput of 18 Gbps ensures minimal latency for real-time PoE devices such as IP cameras and access points operating simultaneously. VLAN support enables isolation of guest, security, and operational traffic without external routing appliances. The switch integrates seamlessly with UniFi Dream Machines, CloudKey appliances, and self-hosted Controller instances running on Linux or Windows.

Installation Notes

Mount the USW-16-POE in a standard 19-inch rack using the supplied SGCC brackets; dimensions are 442 × 200 × 44 mm at 2.8 kg (6.2 lb) unloaded. Connect power before any network cables; the internal supply will self-detect input voltage. Use Cat6A or better cabling for runs exceeding 50 meters to maintain full Gigabit speed. Reserve the SFP ports for fiber uplinks or short-range copper modules if all RJ45 ports are occupied.

Eden Phillips, Infrastructure Specialist

"The Ubiquiti USW-16-POE strikes a practical balance between port density and power delivery. For distributed PoE environments—multi-floor offices, campuses with APs, camera arrays—this switch eliminates the need for external injectors. The 1U form factor and non-blocking architecture mean you're not bottlenecking your PoE devices. VLAN support is straightforward to configure via Controller, and NDAA compliance opens doors in regulated sectors. If you're scaling beyond 16 access points or need 10+ GbE uplinks, step up to the USW-24-POE; otherwise, the USW-16-POE delivers solid value for small-to-medium infrastructure."
