BlackTrax requires a dedicated Power over Ethernet (PoE) gigabit switch or dedicated virtual local area network (VLAN) to connect all the BTSensors with the rest of the system. The switch should have the following:

• A PoE gigabit switch.
• A PoE port for each BTSensor, plus 4 extra to connect to the TimeKeeper, BTRouter, eSync Controller and BTServer.
• PoE switches must support 15.4 watts per Ethernet port.
