Loop-detection with Delta equipement (furnace) shutdown port when power outage.

[ala_ma]

We have a network with ICX7250 switches and loop-detection activated on ports.  On some Delta equipments (for furnace control), when it have a power outage, the switch detect a loop and shutdown the port.  The port come down when the power is lost, not when it come back.  If we make a debug, we can see the loop detection packet come back on the switch.  The equipment continu to make some packet transfert before shuthing down.  If we remove the loop detection protection, the loop goes on the router and make many next hop router errors.  Even if we change that equipement it's the same problem.  For us, it's clear that the problem come from the design of this equipment.  Is there any way to disable loop detection and configure the router to prevent problem coming from that equipment?
Thank you
