power supply built-in. The device consumes up to 44 W leaving
guaranteed 450 W (3×150 W per every 8 Ethernet ports) to power your PoE
devices. Each port can provide up to 30 W of power with any power
output option you choose. The device has a “Dual boot†feature that

the RouterBOOT loader settings. All the feature set comes with
disruptive price, providing best price/performance on the market.
