Power on the Optibit system.
To test the Optibit interface, turn on the PC, plug the RZ or zBus device chassis
power cable(s) into a surge strip or battery backup, then power on. The zBus
chassis do not need to be powered on in any particular order.
The RZ devices have a blue indicator light to show that the device is powered
on. The RZ2 LCD screen will display interface connection information, however,
other RZ devices do not display this information. The zBUSmon utility can be
used to test the device connection. See Testing the Optibit Interface below.
Once a zBus chassis is powered on, the green indicator light on the power
switch will flash regularly (~1 Hz) until communication is initiated by TDT
