A power supply controller in the appliance monitors the state of the power supplies. It ensures that a failed
power supply still gets sufficient direct current from the remaining power supply to light the indicator LED. The
controller also sounds an audible alarm when there is a problem, such as one power supply not being
connected to AC main power.
If only one power supply is present, the audible alarm is silent. If you wish to operate your ProtectServer 3+
External appliance with only one power supply, we recommend that you remove the second supply to silence
the audible alarm.
