Hi
The only problem i have seen personally with 3750x is that you can shutdown all the powersupplies.
this means that if you have 4 powersupplies on two switches and you shut 3 of them down and save the config and you then shut down the forth the switches will reboot due to powerloss,
It does exactly what you told it to do so i cant realy complain about it, but there should be an extra warning that you are shutting down the last powersupply.
nice feature if for some reason you can not reload the switch.
