This versatile product combines switching and Power over Ethernet (PoE) capabilities, making it a significant addition to any network infrastructure.

One of the standout features of the ZyXEL 3356P is its PoE functionality. This device supports Power over Ethernet, allowing it to deliver electrical power along with data to connected devices such as IP cameras, VoIP phones, and wireless access points.
