S-RJ01 with POE-Adapter

I have problems with Routerboards connected with a POE-Adapter to a S-RJ01.
I see packet Loss and FCS Errors on interface of CRS317.
As soon as I remove the POE Adapter and power the board directly it works flawless.

Tried 100MBit and 1GE POE Adapter from MT. Tried different Routerboards and different Ethernet cables.

Tried another S-RJ01 did not help. Replaced with a S+RJ10 resolved the problem.

Plugged S-RJ01 into a RB260GSP and get 100% packet loss with 100MBit POE between. All FCS Errors.

So something is wrong with S-RJ01 modules running with a POE-Adapter between.
One of the modules not working correct:

Part Number: S-RJ01
