*2: Only detectable and indicated when two power supply units are installed and connected to separate, independent power supplies.
*3: Condition of the Status LED will depend on the state of the system.
Note that the XG1200 does not shut itself off when trouble is detected.
Any problems other than those that occur during start up are recorded in the event log. For details of the event log, refer to the "User Guide".
