The PoE powered Switch (aka PoE passthrough switch) is the hybrid device. It not only can power your edge IP device such as IP camera, access point, VoIP phone, it also can receive the power from another PoE switch. That sounds cool right? Imagine you got an existing Ethernet cable in the field, now you can take the PoE powered switch to expand the POE port and add more IP devices in it without rewiring the cable. This is the PoE powered switch.
