Power Over Ethernet Basics & Benefits

PoE (Power over Ethernet) is a method for powering devices using an Ethernet cable connected to a LAN (Local Area Network). Ethernet cables can carry data and an electrical current simultaneously over separate wires. Thus, PoE devices can receive data and power from an Ethernet cable instead of an outlet or adapter.

Standard PoE provides a maximum of 15.4 watts of DC power to each port. PoE+ (PoE plus) can give a maximum of 25.5 watts. Many experts recommend Cat6a cables for PoE purposes, and it is the minimum standard for new commercial installations.

 

PoE is becoming an increasingly popular feature for IP devices. The most popular PoE devices are IP cameras, LED lighting, wall clocks, Wireless Access Points (WAPs), and VoIP phones.

 

Benefits of PoE

 

Decreased Need for Equipment – PoE reduces the need for electrical outlets and power cords for powering devices. This can save funds spent on additional outlets, wiring, and licensed electricians to install them. Devices can also be scheduled to be shut down remotely, decreasing energy consumption and utility costs.

 

Installation Flexibility – PoE can eliminate the need for devices close to electrical outlets. As Ethernet cables come in various lengths, the proper size can be chosen to provide power to a device that may be difficult to reach. For example, this allows an IP camera to be mounted high on a wall.

 

Integrated Safety Precautions – PoE networking components are designed with failsafe features to protect IT infrastructure and devices. This prevents issues such as overloading, under-powering, and improper configurations.

 

Reliable Source of Power – PoE allows power to be transmitted from a  single reliable source, ensuring standardization over all connected devices. A single source eases the task of disabling or resetting PoE devices when it is necessary.

 

Scalability – Adding and powering PoE-compatible devices is more effortless when using the Power over Ethernet approach, allowing network expansion whenever needed.
