Hi guys,

I receive my CRS125 yesterday and i just notice something weird.
All ports are in 1Gbps except the ether3. I test the ethernet cable by switching ether2 and 3, and this is not the problem.

Should i send it back or there is an chance i can fix it by any software update?

CRS125-24G-15-RM
RouterOS 6.37.3 default configuration

Thanks for reading

Under good enough light conditions visually inspect the ethernet connector and see if the pins are good.
Check the link negotiation settings.
Powercycle the board and check again.

I already check the pins and link negociation. But thanks

Since the obvious problem points are eliminated, i think you should return it ASAP.
