16 Before Use
There are three main indicator LEDs on the front of the XG1200: Power LED, Alarm LED, and
Status LED. The following explains the LED display under various conditions.
*1: If the XG1200 is operating normally.
If a problem occurs, the front panel LEDs and the LEDs on the individual parts can be used to
identify the trouble:
*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".
