That particular switch you are using only has two 10GbE interfaces which use X2 based optics, not SFP's. The fact you have mentioned using SFP's makes me think you have cabled the server into 1GbE ports on your switch. If this is the case, it is highly likely the NIC's in the server support 10GbE only and will not operate at 1GbE.
If you can provide the port numbers you have cabled too on the switch and the exact model of NIC in your server I can help out more, and confirm if my suspicion above is correct.
I am not connecting the server to switch in the switch 10GbE interfaces, which use X2 based optics, port. I am connecting the server in other switch port. I know switch other port is not 10GB supported. That is why I have changed the server NIC port speed to 1Gb from BIOS which can do in this server. But still it is not working.
Can u tell me port type of this switch is SFP or not? or is it support SPF type link?
