Is it possible to use four sfp+ as a qsfp+ interface?


I have a pci card that has a QSFP+ interface and I would like to connect it to a DELL switch - S4128F-ON on the SFP+ ports using a QSFP+ to 4x SFP+ cable. What configuration do I need to do on the switch to work this connection?

Unfortunately, I can't help with configurations. But I would like to share the following articles about S series switches that I believe will be useful. I may need to suggest to contact support help line to check if they are able to help you.

Hope that helps!
