What is a Power over Ethernet (PoE) Switch?

A PoE switch is a regular Fast Ethernet or Gigabit network switch that has Power over Ethernet functionality integrated. A Power over Ethernet switch both enables communication among network clients and provides power using the same RJ45 network cable to PoE-enabled edge devices, such as VoIP phones, network surveillance cameras or wireless access points. A PoE switch allows compatible devices to work in places where power outlets or network connections don't exist. This primary function of PoE can save businesses lots of money on the costs of installing electrical and network wiring (more on that below) while still having edge devices work where they are needed. PoE switches exist in many different variations.

What are the benefits of using a PoE Switch?

Installation Cost Savings

It costs a lot of money to bring standard power to locations where there is not any. For example, say you want to add cameras to the part of a warehouse that does not have power outlets. Without PoE, you would need to consult a certified electrician since a network administrator would very likely be unable to complete the electrical installation. However, with the low-voltage application of Power over Ethernet, anyone can run network cables (or PoE network cables) from the cameras to a PoE switch. Using PoE means you also avoid the need of installing power outlets, electrical wiring and breaker boxes, which saves even more money.

Greater Flexibility

PoE edge devices can be easily deployed in locations without power outlets. Since they no longer face the limit of needing a standard outlet to work, those previously hard to reach places can now be accessed with more ease. Installing a PoE network camera high up on the wall or the roof isn’t as daunting a task anymore since you only need one network cable to get power and network connections.

Remote Power Management

A very helpful feature of managed PoE switches is that you can access them over the Internet or local network. This access includes being able to remotely power-cycle edge devices that may have failed. The network camera that crashed or the VoIP phone that needs a reboot no longer needs physical intervention from a person on location. All that is needed for the required restart on either device is to initiate one via the switch management interface.

PoE Watch Dog / Guard / Powered Device Monitor

Some Managed Power over Ethernet Switches can monitor all connected PoE devices and automatically initiate the restart of a device that has failed to communicate for a defined period. Such a feature can be especially useful, for example, in case a security camera stops working in the middle of the night.

What can you power with PoE Switch?

PoE switches are separated by their supported standards. Before choosing your PoE solutions, you need to be aware of how much power your devices draw. With that information, you’ll know which standard and business solution suits your needs.
