Possible Causes
Loose Power Connector: Verify that the power source connector is fully inserted
into the unit's power connector.
'Y' Cable: If you are using the 'Y' cable to supply power to the unit, confirm that
it is connected to a power supply and that the power supply is energized.
Stand Alone Power Supply: If the stand alone power supply is being used
confirm that it is fully inserted into the wall socket.
Wall Socket: Some wall sockets have on / off switches built in. If the socket you
are using has a built in switch, check that is in the on position.
