The CyberData 2-Port PoE Gigabit switch is designed to expand a single PoE network connection into one or two PoE network ports. The CyberData 2-Port PoE Gigabit switch is powered from a single 802.3at or 802.3af network switch and passes that power through to one or two of the downstream switch ports. In the basic configuration, one of the Gigabit downstream ports can drive a VoIP phone directly with PoE and the other Gigabit port can be connected to a user’s PC. No external power supplies would be required.
