Roalan is introducing the NetCom 111 PoE, 113 PoE and 211 PoE serial device servers that are powered over the Ethernet connection. The NetCom 111 PoE, 113 PoE and 211 PoE are upgraded variants of the well known NetCom 111, NetCom 113 and NetCom 211 serial device servers. The new models provide the exact same functions and handling as the existing products, but they benefit from PoE (Power over Ethernet); if this option is used, it avoids the need for an extra DC power supply. In such an installation an Ethernet switching Hub with PoE option inserts the supply currents onto the network cable, which is powers the NetCom servers. If the external power adapter is installed in parallel, this operates as an auxiliary power supply.
