SDX-Compact: The system shows offline after power-on

A powered SDX-Compact can show as offline in SDX-Cloud while its modem is still starting. In one case the modem needed about eight minutes. A restart brought it back sooner, but the cause of the slow start was not found.

Wait first, with a time limit

After power-on, give the system up to 15 minutes. Note the time of power-on and the time the system appears online.

Check the network path

Find out whether the system uses Starlink or its SIM. With Starlink, the SIM stays active as a fallback; see Starlink setup for SDX-Compact. Check whether the Starlink router is online and whether the SIM has signal and a data plan.

Restart once

If the system is still offline after the wait, power it off and on once. Do not switch Starlink on or off while the system runs.

If it comes back, watch it

Note whether the delay returns on the next starts. If the system fails again, or stays offline after a full power-off for several hours and a new start, contact Sodex Support.

What is not known

A restart restored the connection in the reported cases, but it did not prove why the start was slow. Do not treat the restart as a fix.
