This is a silly question and I don't have a switch to test it with but
technically is there any reason why you can't use an uplink port of a switch to connect to a server/pc (10g (sfp+,x2) or 1 gig (sfp, x2,copper)).
Can it be done on the interfaces of sup2t and other supervisors?
On a network module of a 3750x or on a 2960S?
I know you can't use the uplinks on a nexus 2k.
Thanks
