Beginner Basics • Re: CCR2004-1G-2XS-PCIe Router - No Access, No Reset Possible Via Netinstall, No LED, Maximum Continuous Ventilation

During this time I bought another PCIe router card and paid a MTCRE Mikrotik expert to help me configure the card. Since the card is not well known in the Mikrotik ecosystem, the consultancy costs rose to €450, which brought the total cost of the two cards + consultancy to well over €800. More than the cost of CCR2004-1G-12S+2XS! Taking into account my own hourly rate (tens of hours of testing & research), buying router CCR2216-1G-12XS-2XQ would have even been much profitable / wiser.

For those who are interested, there are a lot of learnings and specificities about this card. With a correct configuration and if not unlucky with a faulty card, it works but:
- It has to be mounted on a Linux system for optical transceivers to be recognised (even in router mode, even though it's supposed to be able to be standalone, this isn't 100% the case - won't work if the host is Windows);
- The two SFP28 ports must absolutely be configured at the same speed, which means that if the ISP sends 25 Gb or 10 Gb on the WAN port (Internet access), it needs exactly the same speed on the LAN port (to the local network). Otherwise no link possible on the LAN side;
- With access to 25 Gbe incoming, the test results are very disappointing. The card is a clear bottleneck in router mode.

Unfortunately, the distributor clearly states in its warranty policy that no product, even a faulty one, cannot be returned. So I'm thinking of contacting Mikrotik’s RMA department to return the faulty router PCIe card.
