Non-PoE vs PoE Powered Switches

Non-PoE switches cannot supply power to end devices, so additional power sources and extension cables are needed.

PoE switches can supply power along with data to end devices, minimizing cable usage and saving costs on power outlets, infrastructure equipment, and electrical installation.

Non-PoE switches vs PoE switches

What Can You Power with PoE Switch?

PoE switches are classified by the standards they support, each offering different power outputs. Therefore, knowing the power requirements of your devices is essential before selecting a PoE switch.

Different standards of PoE switch for IP camera setups include:
  • PoE switch (802.3af) for basic IP cameras
  • PoE+ switch (802.3at) for high-definition (HD) pan-tilt-zoom (PTZ) IP cameras
  • PoE++ switch (802.3bt) for PTZ IP cameras with heaters.

Each IP camera type has different power requirements. The table below will assist you in choosing the appropriate standard that offers the power output required for your devices.

PoE Type Power per Port Supported Devices
PoE (802.3af) Up to 15.4 W
  • IP Phones
  • Basic IP Cameras
  • 802.11n Access Points
PoE+ (802.3at) Up to 30 W
  • IP Video Phones
  • PTZ HD IP Cameras
  • 802.11ac (Wi-Fi 5) Access Points
  • Small Audio Speakers
  • Door Locks and Other IoT Devices
PoE++ (802.3bt) Up to 60/90 W
  • IP Video Phones
  • PTZ HD IP Cameras with Heaters
  • 802.11ax (Wi-Fi 6) Access Points
  • Smart Building Lighting
  • Audio System
  • Thin Clients

What are the Advantages of PoE Switches?

  • Simplified Installation: PoE-powered switches eliminate the need for separate power cables for PoE-enabled devices, simplifying installation and reducing clutter.
  • Flexibility and Scalability: PoE switches allow for easy expansion of the network since new devices can be added without the need for additional power outlets.
  • Cost Savings: These switches can lower installation costs and reduce overall infrastructure costs by eliminating the need for separate power supplies and cables.
  • Remote Power Management: Power over Ethernet switches allow for remote monitoring and control of power usage, enabling efficient power management and troubleshooting.
  • Reliability: These switches provide a reliable power source to connected devices, ensuring continuous operation even during power outages when backup power is unavailable.
  • Safety: Ethernet-powered switches are designed to deliver power safely, with built-in protection against overloading, short circuits, and other electrical faults.
  • Energy Efficiency: PoE internet switches can help reduce energy consumption by automatically powering down devices when not in use or by adjusting power output based on device requirements.

How to Select the Right PoE Switch?

Choosing the ideal and best PoE switches involves understanding your network requirements and the capabilities of different switch options. Here's a breakdown of key factors to consider.

Device Power Needs and PoE Standards: You must address your application's power requirements and budgets here.

  • Power Requirements: Identify the maximum power wattage of the PoE devices you plan to connect. (refer above table)
  • PoE Budget: Ensure the switch's budget exceeds the combined wattage needs of your devices.

Network Features and Management: You have to address the features of the switch and the required data speed.

  • Managed vs. Unmanaged:
    • Unmanaged: These are plug-and-play switches, which are ideal for simple networks with limited configuration needs.
    • Managed: These switches offer granular control over network traffic, security features, and PoE power settings, they are better suited for complex networks requiring more customization.
  • Data Speed: Choose a switch with data speeds (typically 1G or 10G) that meet your network's data transfer requirements.

Additional Considerations: There are several other considerations to make in addition to the above.

  • Number of Ports: PoE switches come with fiber ports and Ethernet ports. Select a switch with enough ports to accommodate all your devices with room for future expansion. A fiber PoE switch offers enhanced network flexibility and high-speed fiber optic connectivity.
  • Security Features: Managed switches might offer features like VLANs to isolate network segments for enhanced security.
  • Desktop vs. Rackmount: Desktop switches are compact for smaller deployments, while rackmount switches suit high-density network environments.

Based on Complexity: Here's a simplified approach to choosing based on complexity.

  • Simple Home/Small Office Network: You can choose unmanaged PoE switches with enough Gigabit ports and PoE budget for your devices (likely PoE+ for future-proofing).
  • Complex Business Network: To meet demanding network requirements, you can choose managed PoE switches with advanced features, scalability, and security options.
