RocketLinx PoE Feature: Voltage Boost (VB)
RocketLinx ES7106-VBAll of our RocketLinx VB switches are capable of being powered directly from low voltage 12 and 24 volt sources. This is important, because PoE switches need to power devices with 48VDC output.  This usually requires an extra power supply.  However, VB switches overcome this by incorporating special DC-DC conversion circuitry that allows the switch to be powered by the lower voltage and ups the voltage internally to output 48 volts on the PoE lines.
