This article provides tables with information on the supported Power over Ethernet (PoE) output and input modes for Ubiquiti UniFi Switches, Access Points, Cloud Keys and Cameras.NOTES & REQUIREMENTS:
- See each device’s Datasheet, available in their store product page or in the Downloads section, for more information on the supported PoE modes.
- See our PoE Adapters page for more information on Ubiquiti PoE adapters/injectors that can be used to power on devices.
- There is more information on PoE in the Power Over Ethernet (PoE) article.

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 as 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 the different UniFi Access Point (UAP), UniFi Dream Machine (UDM), and UniFi Security Gateway (USG) models, and cost well under the amount of the midspan device alone.
UniFi Switches – Supported PoE Output Modes
Ubiquiti devices use
Active PoE output. This means that the voltage the Powered Device (PD) needs is negotiated. There are three output modes:
PoE: Uses IEEE 802.3af standard to deliver up to 15.4W.
PoE+: Uses IEEE 802.3at standard to deliver up to 30W.
PoE++: Uses IEEE 802.3bt standard to deliver up to 60W.
Different switches provide different output methods, so it’s important to learn what power method the UniFi switches support and compare it with the power method needed to power the different UniFi devices: eg. UniFi access points, cameras or Cloud Keys.
It’s important to note that each switch has a maximum power consumption which should be considered when powering multiple UniFi devices via PoE. For example, a US-16-150W has a 150W maximum power consumption, even though it has 16 ports. The UAP-HD has a maximum power consumption of 17W. Therefore, if you were to power 16 UAP-HD on a US-16-150W, there is a possibility that the wattage could exceed what the switch is capable of supplying in certain conditions. Find each device’s power consumption in their Datasheets, found in the Downloads page, within each product’s Documentation section.

UniFi Access Points – Supported PoE Input Modes
NOTES: * The IW models only support PoE Pass-Through when powered by 802.3at.** UAP-AC-LRs with a date code prior to 1634 or board revision before 17 only support 24V passive PoE.
*** UAP-AC-LITEs with a date code prior of 1634 or board revision before 33 only support 24V passive PoE.
