PoE Switches: Power Devices Over Ethernet

Power over Ethernet (PoE) switches deliver data and electrical power through a single ethernet cable, simplifying installations and reducing cabling costs. Island Electrical Supply carries PoE switches from Ubiquiti, HPE, TP-Link, D-Link, and Cisco in configurations from 8 to 48+ ports.

Best for: Installers and IT teams powering wireless access points, IP cameras, VoIP phones, and IoT devices without running separate power cables.

PoE Standards

Match the PoE standard to your devices:

  • PoE (802.3af): up to 15.4W per port for VoIP phones and basic access points
  • PoE+ (802.3at): up to 30W per port for modern WiFi 6 access points and PTZ cameras
  • PoE++ (802.3bt): up to 60-100W per port for WiFi 7 access points, video conferencing systems, and LED lighting

Calculating Your PoE Budget

Add up the wattage required by all connected devices and select a switch with at least 20% headroom. A typical deployment with 24 access points drawing 25W each needs at least 720W of total PoE budget. If you need PoE power for a single device, see our PoE Injectors for a simpler solution.

Frequently Asked Questions

What is a PoE switch?

A PoE switch sends electrical power along with network data through standard ethernet cables. This lets you power devices like wireless access points, IP cameras, and VoIP phones from the switch without running separate power cables to each device.

How do I calculate my PoE budget?

Add the maximum power draw (in watts) of every PoE device you plan to connect. Then add 20-30% headroom for future devices. For example, 10 access points at 25W each equals 250W minimum, so choose a switch with at least 300-325W of total PoE budget.

Can I mix PoE and non-PoE devices on the same switch?

Yes. PoE switches detect whether a connected device needs power. Non-PoE devices like computers and printers connect normally and only receive data. The PoE power is only delivered to devices that request it through the PoE handshake.
