Troubleshooting Using the Status LEDs

The front panel Status LEDs can provide “local” status information about SecureSync. Observe the front panel Status LEDs and use the table below to find the recommended troubleshooting steps or procedure for the observed condition.

LED Current Status Indication Troubleshooting

Power

LED is blank (not lit).

SecureSync has no AC and/or DC input power applied. 1) Verify AC power is connected to an AC source and AC power switch is ON.
2) Verify DC power (within the correct voltage range, as stated on the DC connector) is applied to the DC power connector.
3) See Unpacking and Inventory

Sync

LED is off

No valid Reference inputs available since power-up. 1) Make sure the Input Reference Priority table has the desired inputs enabled, based on desired priority.
2) Make sure the desired input references are connected to the correct port of SecureSync.
3) See Configuring Input Reference Priorities

Sync

LED is orange

Holdover mode: All available inputs have been lost. 1) Make sure the Input Reference Priority table still has the desired inputs enabled, based on desired priority. See Configuring Input Reference Priorities.
2) Make sure desired input references are still connected to the correct port of SecureSync.
4) Verify GNSS antenna installation (if applicable).
See Troubleshooting GNSS Reception.

Sync

LED is red

Time Sync alarm: SecureSync was just powered-up and has not yet synced to its references. Or, all available reference inputs have been lost and the Holdover mode has since expired. Note: If SecureSync was just recently powered-up or rebooted and input references are applied, no troubleshooting may be necessary. Allow a few minutes for the input reference to be declared valid (allow 35 – 40 minutes for a new install with GNSS input).
1) Make sure the Input Reference Priority table still has the desired inputs enabled, based on desired priority. Refer to Configuring Input Reference Priorities.
2) Make sure desired input references are still connected to the correct port of SecureSync.
3) Verify GNSS antenna installation (if applicable). Make sure the antenna has a clear view of the sky.
