The 24-Ports Gigabit IEEE 802.3at PoE+ Managed Injector Hub (440 watts) (Part number: POE-2400G) from Planet is a Power over Ethernet (PoE). PoE (Power over Ethernet) products transmit both power and data across the internal cores of an Ethernet cable technology, enabling to get power to hard-to-reach areas. Nowadays they are an integral part of homes network setup, helping to remove the need of having other power cables since PoE devices are powered by ethernet cables.
