Connect ME 9210 ethernet negotiation loop

We use a Spellman unit with a Digi Connect ME 9210 and have ethernet connection issues when using a Siemens Siemens xb005g G-bit switch.

In the video below you can see how the unit starts looping after a power cycle and recovers after unplug the Ethernet cable for a couple of seconds.

Before there was a Digi Connect ME unit on the boards and we have never had this problem with the old units.

Any hint on how to debug this problem or a solution for this problem.

Extra info it might be that the watchdog triggers because this is a gigabit switch. Don’t know if this is an option.

what firmware version do you have on the module?
You might want to open a support case by sending an email to Tech.Support@digi.com

This is the firmware version.

NET+OS 7.5.2.2
