Ubiquiti USW-LITE-16-POE UniFi Network Switch

Ubiquiti USW-LITE-16-POE UniFi Network Switch

Overview

The Ubiquiti USW-LITE-16-POE is a compact, managed Layer 2 switch designed for small-to-medium UniFi deployments where space and power efficiency are critical. This 16-port gigabit switch delivers 32 Gbps switching capacity with 16 Gbps non-blocking throughput and a 24 Mpps forwarding rate, making it suitable for access-layer deployments in offices, retail locations, and remote sites. The switch accepts universal AC input (100–240V, 50/60 Hz) and measures just 192 x 185 x 44 mm, enabling flexible mounting on desktops or walls without consuming significant rack space. With a 60W internal power supply and 45W PoE+ budget, the USW-LITE-16-POE can power 16 PoE devices simultaneously, eliminating the need for separate power infrastructure across distributed endpoints.

Key Features

Management is handled entirely via Ethernet, integrating directly into UniFi's centralized controller for VLAN configuration, traffic shaping, and device monitoring. The switch supports up to 1,000 VLANs, enabling network segmentation across multi-tenant or security-zoned deployments. Polycarbonate enclosure construction keeps overall weight to 1.2 kg while maintaining durability across typical office and light industrial environments. The USW-LITE-16-POE (model MPN USW-LITE-16-POE) operates reliably from -15 to 40°C, covering standard indoor and some outdoor sheltered installations. The device carries NDAA compliance and CE, FCC, IC, and Anatel certifications, meeting regulatory requirements for enterprise and government procurement. Power consumption excluding PoE output is minimal at just 15W, reducing operational costs in always-on deployments.

Deployment Scenarios

Common use cases include branch office switches where space is constrained, PoE-powered access point clusters in multi-floor buildings, and edge distribution points feeding VoIP phones, wireless controllers, and IP cameras. The switch's compact form factor and low power profile make it ideal for small server rooms, network closets, or wall-mounted cabinet installations. Organizations building micro-segmented networks benefit from the 1,000 VLAN capacity, while the 45W PoE+ budget supports mixed loads of powered devices without requiring supplemental PoE injectors.

Network Integration

The USW-LITE-16-POE integrates seamlessly into UniFi ecosystems, appearing within the controller dashboard for centralized policy management. All 16 ports operate at 1G speed, and the non-blocking throughput architecture ensures no port-to-port congestion under full duplex operation. Ethernet management eliminates proprietary management ports, simplifying cabling and reducing per-device overhead.

Installation Notes

Mounting is straightforward via the included wall-mount hardware or desktop placement. The switch's compact dimensions and light weight (2.6 lbs) allow installation in tight spaces. AC power connection via standard outlet or UPS integration is recommended for business-critical deployments. No additional configuration beyond controller discovery is required for basic operation; advanced VLAN and QoS settings are pushed from the UniFi controller.

Marty Allison, Infrastructure Architect

"The USW-LITE-16-POE fills a real gap for organizations rolling out distributed UniFi infrastructure. Its 45W PoE budget and compact footprint make it cost-effective for powering small clusters of access points or edge devices without the complexity of larger managed switches. The NDAA compliance is also valuable if you're working with government or defense contractors. Just ensure your controller deployment is stable before relying on it as a core switch—redundancy at the edge layer is still a best practice."
