UniFi - Supported PoE Protocols


Overview


This article provides information on what PoE output each UniFi Switch supports and what PoE input is supported by UniFi access points, Cloud Key, cameras and voice over IP phones. Please use the tables provided to cross-reference and find the correct switch to power your UniFi devices.

NOTES & REQUIREMENTS:
The most updated information will always be included in each product's Datasheet, found at the bottom of each product page when navigating from our here.
 
There is also a helpful UniFi AP and Video Camera Compatibility table at the end of the UniFi PoE Switch Datasheet. Find more information on PoE Protocols in the Related Articles below.

Introduction

One of the challenges with large PoE deployments is figuring out how to provide power to your UniFi access points. When you have many access points it becomes less viable to power devices using AC PoE Injectors. With non-PoE capable switches, you can add a Midspan device which acts a collection of individual PoE injectors by receiving ethernet from the switch with only data being transmitted and adding power out over ethernet through the connection. Such a piece of equipment takes up additional space on your rack, while also costing you a lot of money.

To help with such deployments, UniFi Switches come in a few different models with varying numbers of ports from 8, 16, 24 and 48. These switches are endspan devices as they act as both the switch and provide PoE to devices. UniFi switches give you greater functionality when used with UniFi Access Points (UAPs) or UniFi Security Gateways (USGs) and cost well under the amount of the midspan device alone.

NOTE: US-16-XG, US-24, US-48 were designed to be used in applications where PoE output is not required, therefore do not offer any PoE out capabilities.
