Hi, I just received an X410 and I am having trouble getting the 100Gb link to work.
- On the workstation side, my NIC is an Intel E810 CQDA2 and I am using UHD-4.8 with Ubuntu 24.04 LTS - On the X410 side, I loaded the UHD-4.8 file system and the UC_200 FPGA image which implements 100Gb on SFP1. - Finally, I am using Fiberstore CWDM4 100Gb <https://www.fs.com/products/65219.html?now_cid=1159> optical transceivers with a duplex single-mode fiber. This item is my current suspected culprit - it's not clear to me whether the operation of this optical transceiver is transparent to the 100Gb port or if the port needs to handle things differently for this type of CWDM transceiver The problem is that I never even get link lights on the workstation NIC when I connect to the X410. However, if I move the QSFP28 transceiver from the X410 to another workstation (with a Mellanox 100Gb NIC), the link lights come right up on both sides and the OS sees a 100Gb Ethernet link. So, the problem "appears" to be that the X410 does not like this optical transceiver. Does anyone have any experience using this optical transceiver with the X410? Thanks. Rob
