3-port switch PoE

A 3-port PoE switch provides network connectivity and power to devices like IP cameras or access points, typically supporting IEEE 802.3af/at standards with gigabit speeds.

Key Features

Port Configuration: Most 3-port PoE switches include 2–3 RJ45 ports capable of gigabit speeds (10/100/1000 Mbps). Some models also include an uplink port for connecting to a larger network . PoE Standards: These switches generally support IEEE 802.3af (15.4W per port) and IEEE 802.3at (30W per port), allowing them to power devices such as IP cameras, VoIP phones, and wireless access points directly through the Ethernet cable . Power Budget: Total PoE power varies by model. For example, the TP-SW3G switch provides a 60W total PoE budget, while other models like the ONV-POE33032PL can deliver up to 30W per port with an external 65W power supply . Management: Many 3-port PoE switches are unmanaged, meaning they are plug-and-play and require no configuration, making them ideal for small networks or home setups . Some models may offer basic management features for prioritizing PoE ports or monitoring power usage. Extended Features: Certain switches include extended transmission capabilities, allowing PoE to reach beyond the standard 100 meters, sometimes up to 200 meters, which is useful for larger installations like campuses or hotels .

Use Cases

• Small office or home networks where only a few PoE devices are needed.
• IP surveillance systems powering cameras without separate power adapters.
• Wireless access points in areas without nearby power outlets.
• VoIP phones in compact setups.

Example Models

• TP-SW3G: 3-port gigabit PoE switch with 60W total power, supporting IEEE 802.3af/at .
• ONV-POE33032PL: 3-port gigabit switch with 2 PoE ports, 30W per port, external 65W power supply, plug-and-play, suitable for small to medium deployments . These switches are compact, cost-effective, and ideal for scenarios where only a few PoE devices need to be connected and powered without complex network management.
