The Vi00016 can be used virtually with any network switches or Midspans to combine the PoE output of two ports and double the PoE power. It increases PoE power beyond the normal 30W to provide power for extended distance applications and those requiring high power PoE++. The Vi00016 is easy to install and does not require any modification to the PoE source devices.The Vi00016 is an ideal solution for applications where the PoE power of a single port is limited and connected devices require higher PoE power.
