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.
