What is power over ethernet used for.

What is power over ethernet poe and what is it used for. To find out about the myths and misconceptions about power over ethernet options for high power poe and a little more about how the technology works please continue to poe explained part 2. The main reason to use poe over the conventional power supply system is to reduce the cost of providing power supply to each peripheral that connects to the network. Power over ethernet is injected onto the cable at a voltage between 44 and 57 volts dc and typically 48 volts is used.

Poe technology relies on the ieee 802 3af and 802 3at standards which are set by the institute of electrical and electronics engineers and. Our power without the struggle white paper makes the case for poe deployment in more detail and explains how poe can be used effectively. How power over ethernet works and why it is used.
