The PowerBox Pro is an outdoor five gigabit ethernet port router with PoE output on four ports. Since the device has a weatherproof outdoor case, you can mount it on a tower, or in other outdoor locations. It also supports passive or standard 802.3at/af PoE input/output. Ethernet ports 2-5 can power other PoE capable devices with the same voltage as applied to the unit. Less power adapters and cables to worry about! It can power 802.3at and af mode B compatible devices, if 48-57 input voltage is used.
