What is Power over Ethernet (PoE)
Power over Ethernet (PoE) provides power and network connectivity for PoE-powered devices over a single network cable. It's a 2-in-1 solution, so you don’t have the restriction that your devices are close to a power outlet. PoE devices range from wireless access points, IP cameras, VoIP phones, PoE LED lighting, PoE speakers to IoT doorbells and other IoT devices. These devices are powered and in some cases manageable by our PoE switches.
Without PoE
With PoE
One Ethernet cable provides power AND connectivity
Features
LOWER INFRASTRUCTURE AND INSTALLATION COSTS
Fewer, separate power adapters are needed and only one cable run is required rather than two.
CENTRALIZED CONTROL
Manage power to devices from a centralized switch. Power down/up devices as required for energy and cost savings.
NO NEED FOR ELECTRICIANS
Uses existing IT networking infrastructure.
EXTENDS WIRED AND WIRELESS NETWORK REACH
Not limited to fixed power outlet placements.
OVERCOMES HARD TO WIRE ENVIRONMENTS
Including old or ‘protected’ buildings.
RELIABILITY
Redundant Power Supply (RPS) backup options helps keep devices running even in the event of a power outage. Important for business critical services, such as IP Telephony based Call Centers.
PoE (802.3af)
Type 1:
The original PoE standard provides 15.4W of power to the Ethernet port to be sent = 12.95W of delivered power at 100M distance from the switch.
PoE+(802.3at)
Type 2:
PoE+ effectively doubles the PoE power to the device by providing 30W of power to the Ethernet port to be sent = 25.5W of delivered power at 100M distance from the switch.
PoE++(802.3bt)
Type 3 and 4:
PoE++ (bt) now effectively doubles the PoE+ power to the device by providing 60W (Type 3) or 90W (Type 4) of power

What can you power with PoE?
Each PoE port powers up to 15W at a very short distance. Power delivered at a longer distance (up to 100m) is 12.95W. Typical devices needing less than 12.95W are:
- IP Phones with small or no display
- Indoor Wireless 802.11n or 2x2 Wireless 802.11ac Access Points
- Simple IP Cameras
What can you power with PoE+?
Each PoE+ port powers up to 30W at a very short distance. Power delivered at a longer distance (up to 100m) is 25.5W. Typical devices needing less than 25.5W are:
- IP Phones with a large display, video phones, conference systems
- Up to 4x4 Wireless 802.11ac (WiFi 5) or 2x2 802.11ax (WiFi 6) Access Points
- Pan-Tilt-Zoom HD IP Cameras without heaters
- Small audio speakers
- Door locks and other IoT devices
What can you power with Ultra 60 PoE++?
Each PoE++ port powers up to 60W at a very short distance. Power delivered at a longer distance (up to 100m) is 51W. Typical devices needing less than 51W are:
- IP Phones with a large display, video phones, conference systems
- Up to 4x4 Wireless 802.11ax (WiFi 6) Access Points
- Pan-Tilt-Zoom HD IP Cameras with heaters
- Ceiling tiles LED Lighting
- Large audio speakers
- Digital signage displays
- AV over IP encoders/decoders
