Hi.
Just got a new CRS504-4XQ-IN and I'm trying to connect a Luxtera QSFP28 100Gb PSM4 module to it I got off eBay.

When I connect the QSFP module the CRS504 starts spinning fans up and down all the time and I loose connection with the switch. If I unplug the QSFP module I immediately get in contact with the switch again and fans quiet down, no need to reboot. I can't see any errors in the logs...
- Anyone experienced similar behavior?
- What is the behavior of the CRS504 when you use an incompatible module?
- Is the QSFP28 a standard, and "all" modules should more or less work in the Mikrotik, or do I need to be aware of some specific specs?
I don't have any other QSFP modules at the moment (getting 5pcs of the cheap Intel 100Gb ones next week) to compare with.
Edit: I'm running default config, just added DHCP to Bridge to get IP-address. Tried both v7.9.2 and v7.10rc1 with the correct Routerboard firmware.
Thanks.
