Why Power Over Ethernet? Now you can install your NUC where you need it, regardless of whether or not it will be close to an outlet. The costs and infrastructure required to install traditional AC outlets can drive up your project budgets and extend your schedule. With the GBT-NUC lid, you can use IEEE 802.3bt or uPoE to deliver power and data to your NUC for AV, conferencing or any other application.
