The 2970 series also had issues with electrical imbalances. These really need to be chassis grounded where other switches aren't as sensitive. <sarcasm>Not that anyone ever fails to attach grounding cables to switches.</sarcasm> If you are running more than one Ethernet cable to the same device from the 2970 you can have issues with the poor handling of imbalances.

The physical design appears to be the same as 3550-12G and some of the 3750. The extra height is taken up by the PS and 2 fans which are on their own shelf, as there is no room behind the mainboard, since the mainboard is deeper. This is 1 more fan then many of the 1U switches have. Overheating hasnt been a problem. They all run from warm to hot to the touch, from the 3500/2950 and up. Your servers will complain well before the switch does.
