Why is the Sync Status LED red on my Orolia EdgeSync Switch?
- CCarlos MayAug 16, 2025
If the Sync Status LED on your Orolia Switch is red, it could mean a few things. First, if the MCE is in GNSS Only mode, ensure the GNSS LED is green. Second, if in PTP Only mode, check that Port 1 or Port 2 is connected to a PTP Grand Master and that the Grand Master is sending PTP timing messages. Third, if operating in GNSS/PTP Primary/Secondary mode, verify both GNSS (GNSS LED is Green) and PTP connections. Fourth, if you're using external 1PPS/ToD inputs, connect the input sources on the EdgeSync Front Panel and enable 1PPS In and ToD In on the Interface :: GNSS webpage. Finally, check the Alarms/Events Tab Webpage for any EdgeSync alarms affecting the timing inputs.
