Building an IoT Network with a PoE Switch: What You Need to Know

The Internet of Things (IoT) is a rapidly growing technology, allowing devices to communicate with each other and the cloud. One of the most useful elements of this network is the use of Power over Ethernet (PoE) switches. PoE switches enable organizations to power their IoT devices while simultaneously using a single cable to connect them to the network. But what exactly is a PoE switch and how can you get started building an IoT network with one? In this blog post, we’ll discuss everything you need to know about PoE switches and how you can use them to build your very own IoT network.

What is a PoE Switch and How Does it Work?

A PoE switch is a type of network switch that delivers power over Ethernet (PoE) to powered devices (PDs). A PD can be any device that can receive power from an Ethernet cable, such as a VoIP phone, IP camera, or wireless access point.

A PoE switch typically contains two types of ports: PoE and non-PoE. The PoE ports deliver power to PDs, while the non-PoE ports are used to connect devices that don’t require power, such as computers and printers.

Most PoE switches use the IEEE 802.3af or 802.3at standard to deliver power. This standard defines four levels of power: 12.95 watts (Level 1), 25.5 watts (Level 2), 51 watts (Level 3), and up to 90 watts (Level 4).

The amount of power delivered by a PoE switch depends on the number of ports in use and the level of power required by each PD. For example, a 24-port PoE switch with all ports in use at Level 3 would require 1,224 watts of power.

To calculate the maximum number of devices that can be powered by a PoE switch, divide the total wattage output of the switch by the average wattage consumed by each device. For example, if a 48-port PoE switch has a total output of 1,000 watts and each device consumes an average of

Why Use a PoE Switch for Your IoT Network?

There are many reasons to use a Power over Ethernet (PoE) switch for your Internet of Things (IoT) network. PoE switches can provide power and data connectivity to devices on the network, which is ideal for IoT devices that may not have a power source nearby. In addition, PoE switches are typically more reliable than non-PoE switches and can offer greater flexibility in terms of network design.

Another benefit of using a PoE switch is that it can help reduce the overall cost of the IoT network. By providing power to devices through the Ethernet cable, PoE switches eliminate the need for additional power cables or outlets. This can make installation and maintenance of an IoT network much easier and more cost-effective.

Finally, PoE switches can offer improved security for an IoT network. By centralizing power distribution, PoE switches make it more difficult for unauthorized individuals to access and tamper with devices on the network. This increased security can be especially important for critical IoT applications such as medical or industrial networks.

The Different Types of PoE Switches

There are a few different types of PoE switches on the market today. Managed and unmanaged PoE switches are the two most common, but there are also mid-range and industrial options available. Here’s a quick rundown of each type of switch and what it offers:

Managed PoE Switch: A managed PoE switch gives you more control over your network. You can configure settings, monitor traffic, and troubleshoot issues more easily with a managed switch. These switches also offer more advanced features than unmanaged switches, such as Quality of Service (QoS) and port mirroring.

Unmanaged PoE Switch: Unmanaged PoE switches are easier to set up and don’t require any special configuration. They’re a good option if you’re looking for a basic PoE switch that just gets the job done. However, because they lack features like QoS and port mirroring, they may not be suitable for more complex networks.

Mid-Range PoE Switch: Mid-range PoE switches offer a happy medium between managed and unmanaged options. They usually have more features than an unmanaged switch, but they’re not as feature-rich or expensive as a managed switch. Mid-range switches are a good option for small to medium businesses that need some extra features without all the bells and whistles of a managed switch.

Industrial PoE Switch: Industrial PoE switches are designed for harsh environments and can withstand extreme temperatures

How to Choose the Right PoE Switch for Your IoT Network

If you’re looking to build an IoT network, one of the most important components you’ll need is a PoE switch. But with so many different types and brands of PoE switches on the market, how do you know which one is right for your needs?

Here are a few things to keep in mind when choosing a PoE switch for your IoT network:

  1. The number of ports you need: The number of ports on a PoE switch will determine how many devices you can connect to it. If you only have a few devices, then a small 8-port switch should suffice. But if you have dozens or even hundreds of devices, then you’ll need a larger industrial-grade switch with 24 or more ports.
  2. The type of devices you’re connecting: Not all PoE switches are created equal. Some are designed for powering IP cameras, while others are better suited for VoIP phones or wireless access points. Make sure to choose a switch that’s compatible with the type of devices you’re using.
  3. The power requirements of your devices: Depending on the power requirements of your devices, you may need a higher-powered PoE switch. For example, if you’re connecting IP cameras that require 802.3at (also known as “PoE+”), then you’ll need aswitch that supports that standard. Conversely, if your devices only require the older 802.3af standard, then anyPoE switch will

Tips for Installing and Using a PoE Switch

A PoE switch can be a great addition to any IoT network. Here are a few tips to help you get the most out of your PoE switch:

  1. Make sure that your PoE switch is compatible with the devices on your network. Not all PoE switches are compatible with all devices.
  2. Plan your network carefully. Decide which devices will be connected to which ports on the PoE switch.
  3. Follow the instructions that come with your PoE switch. This will help you avoid any potential problems during installation and use.
  4. Pay attention to the LEDs on the front of the PoE switch. They can give you valuable information about the status of your network connections.
  5. Use quality Ethernet cables to connect your devices to the PoE switch. Cheap cables can cause problems with data transfer and can even damage your equipment.


Building an IoT network with a PoE switch can be a great way to quickly and easily expand your connected devices. With the right knowledge and understanding of what you need, such as an Ethernet cable, a router, and PoE switch that supports all the power requirements for your IoT devices, you’ll be able to create an efficient and reliable network in no time. With the ability to control multiple devices from one central location, creating an IoT network is sure to save you time and help keep everything running smoothly.
