Getting Started With Your System
The connectors on the back of your system have icons indicating which cable
to plug into each connector. Be sure to tighten the screws (if any) on the
monitor's cable connector.
NOTE:
If you simultaneously connect two monitors to the system, using the front
and back video connections, the video will default to the front since only one
display can operate at a time.
Connecting the System and Monitor Power Cables
Connect the monitor's power cable to the monitor (optional). Connect the
system’s power cables to the system.
Plug the other end of the power cables into a grounded electrical outlet or
a separate power source such as an uninterrupted power supply (UPS) or a
power distribution unit (PDU). If possible, connect the power supplies to two
different 110V power sources or two different 220V power sources, depending
on the power sources used.
