Can a powered PoE switch be connected to another switch
Yes, you can connect two PoE switches together, and this is a common scenario in many networking setups. The power draw would be too great. While it is quite rare and has power limitations (as incoming power has to be split accross child connections). PoE devices are network equipment that can send out or receive the PoE power along with data, such as PoE switches, IP cameras, wireless access points, while non-PoE devices can only. PoE (Power over Ethernet) technology allows switches to deliver both power and data over a single Ethernet cable—perfect for powering devices like IP cameras, VoIP phones, and wireless access points. But not all devices and switches support PoE.
