Backplane connections in the 4000 (and 4500) chassis are 6 connections of 1G each per slot.

So in the 48 port blades 8 ports share the same 1G connection. This was fine in the past, as 8 100Mb ports fit nicely.

4000/4500 Catalysts were never positioned as server of aggregation switches, they are access switches for a bunch of desktops.
