Maybe, but -most- of the time that you see an Uplink port on something, it indicates that the device is a switch and not just a hub.

It usually has an internal cross-over, and when in use one of the plain ports often must be un-occupied.

Most of the time I saw this it was a port wired such that a non-crossover cable would work from the uplink port to a regular port on another hub.

But it's been more than a few years.
