How many ports does it really have? The "Specifications" tab says five "Primary" ports and *no* "Uplink" port, but the picture in the gallery shows ports Up-LINK,1X,2X,3X,4X,5X. On the picture of the front, there are pairs of lights labeled 1X,2X,3X,4X,5X but none labeled Up-LINK. HOWEVER, to the left of the word "Power" there is a *pair* of lights. Is that additional pair for the Up-LINK? I cannot tell whether the word "Power" has a separate light.

I purchased several of these last year for use at various locations. There is no uplink port. And no need for a special cable for up- linking. Just plug in your cable from PC or router or another switch to any of the ports and then attach any ethernet enabled device (PC, TV, Switch, Router, Printer etc) to any or all of the other 4.
