Hello Jeff, Partial success. The card is now able to use an SFP+ optic. It warns me when the optic is installed: Mar 22 16:49:45 r720-01 kernel: WARNING: Intel (R) Network Connections are quality tested using Intel (R) Ethernet Optics. Using untested modules is not supported and may cause unstable operation or damage to the module or the adapter. Intel Corporation is not responsible for any harm caused by using untested modules. I cannot use an SFP+ optic at the switch. The connection just does not happen. If I go back to the original SFP optic, the connection occurs, as expected at 1G. On the switch side, I've tried a known good optic from an existing connection. I could install an PRO/10GbE instead, that has a built-in transceiver. I have two of those in use now, both working on 10G. Ideas? Thank you.
