Powering the Spurs
For devices using hardware revision 010, you can only use COM2 and COM3 to create module network spurs
when the network repeater is connected via ethernet. In this scenario, COM1 is only used for supplying power to
the network repeater.
The COM2 and COM3 ports are powered separately and are optically isolated from each other. An independent
battery backed power supply unit is required for each spur.
