Hi,
We have a pair of Mellanox SX1710's that we have connected to two servers with HP FlexFabric 560SFP+ adapters using a pair of Mellanox MC2309130-002 cables. The servers are running Windows 2012 R2.
We are not seeing any connectivity between the switches and servers (either of them) and no link lights at either the switch or the server. Inside the OS the adapters are showing as unplugged. However, if we connect the two servers together (HP FlexFabric 560SFP+ <-> HP FlexFabric 560SFP+) we are able to establish connectivity between the two of them. Also we aren't having this issue with other servers connected to these switches.
I've tried switching the interfaces between autosense, 10Gbps, and 1Gbps within Windows to no avail.
Any help would be appreciated.
Thanks!
Mike
