1.3.2 Status LEDs
Three Status LEDs (see "SecureSync front panel layout (SAASM version)" on page4), located
on the unit's front panel, indicate SecureSync's current operating status:
POWER: Green, always on while power is applied to the unit
SYNC: Tri-color LED indicates the time data accuracy
FAULT: Two-color, three-state LED, indicating if any alarms are present.
At power up, the unit automatically performs a brief LED test run during which all three LEDs
are temporarily lit.
