Power Over Ethernet (POE)
Power Over Ethernet (POE)
In addition to the data that cable typically transports, Power over Ethernet (PoE) technology sends electric power over twisted-pair Ethernet cable to powered devices (PD), including VoIP phones, IP cameras, and wireless access points. Instead of using separate cables for data connections and electric power, it allows PDs to be powered by a single RJ45 wire.
What are the benefits of PoE?
PoE can cut down on the time and cost of installing electrical power cabling. An electrician with the necessary skills is not needed to install network cables. Money is saved by requiring fewer power outlets for each installed gadget. Because it enables centralized management over heating and cooling, window shades, and lighting, it also lowers energy expenses.
Without being tethered to electrical outlets, devices such as monitors, security cameras, and wireless access points can be positioned in ideal locations and be easily repositioned if moved.
Power delivery using PoE is designed to intelligently protect network equipment from overload, underpowering, and incorrect installation. It also eliminates the danger of working with or around dangerous high-voltage power sources.
PoE power comes from a central and universally compatible source and not from a collection of distributed wall adapters. It can be backed up by an uninterruptible power supply (UPS), allowing for continuous operation even during power failures. PoE also allows for devices to be easily disabled or reset from a centralized controller.
Having power available on the network means that the installation and distribution of network connections are simple and effective.
