Hi,
I am trying to connect to Summit X450e48p via the shared sfp ports. EXOS Ver 12.5.3.9
Server has an Intel X520-2 Nic installed and I am using a 3m 10G SPF+ Passive direct Attach Copper TwinAx cable. I get no link light. Am I missing something obvious? I am new to Summit Switches and EXOS, so I am not sure where to even check to see if the ports are enabled. Is it a compatibility issue?
Please advise.
Thanks.
David

The cable works fine between two switches. The X520-2 NIC, however, according to Intel, only supports 10 GB when using a direct attach cable. If the ports are only gb, then that would be my issue. Thanks for the feedback.

450 shared ports on the front are 1 gig only Unless you mean the 450 G2 but I believe the model number you're sharing those are 1 gig ports and this setup will not work

It could be an OS and driver issue. Which OS do you run on a server and which driver version you have? Also you may try to get a link if you connect the cable between two ports of a NIC just to verify if the cable is capable to your NIC

Many servers require active cables. Try optics and fiber if available.
Some servers also require vendor specific cables.
Do you get a link if you connect the cable between 2 450s? If you strip all VLANs you should be able to loop it back to the same switch for testing, without causing an issue.
