Re: I have windows 2012R2 OS on Dell R710.When i connect mellanox nics and cables through a Dell switch with 40G ports, It shows network cable unplugged.

Thanks guys,Im able to get access to nics now. But the performance is not up to the mark.

Should I do any changes on the nic parameters, as of now i have kept the default settings. Im using windows 2012 R2 server.
