Notes:
2970G-24TS is 2.59 in. (6.59cm) high and 11.60 in. (29.46 cm) deep, same width as -24T. While the 2950G's have similar internal forwarding engines, a 2950G-12-EI, for instance, will never fully use the available bandwidth or forwarding rate. The numbers given are for capacity, not "fill-ability.
