Haven't seen anything... we have about 350 X's installed so far.

We have about fifty 3750X's at this time. The only issues we've had with them were some bugs in two versions of firmware. One bug generated Traceback errors and caused the switch to reboot (this affected six switches) when you tried to set a password, and the other wouldn't allow you to control the power allotted per-port (this affected one switch). Firmware upgrades resolved all of these issue, and we have found them to be solid switches since. ______________________________ Please excuse any errors in spelling or grammar as this e-mail has been sent from my mobile phone.

We use mostly 3560x’s since they are much cheaper. We only use 3750’s when we need stacking which we mostly use when we want to have as much redundancy as possible for say a building aggregation. We haven’t had any particular problems with them, but again, where we have them installed, everything is redundant, so if we did, it wouldn’t bring the network down, but it would get old if it happened often. We install redundant power supplies in every switch we install now. We plug one end into UPS and the other end directly into the grid. This way if a UPS goes bad (which happens all too often) you are still up and running. And, of course the power supply or fan can go bad on these as well and you can swap them live.
