We have had 3com and now dlink switches fail at a single building at a disturbing ratio. We have not determined the exact cause of failure but the symptom is just all the lights flashing on a single switch in a daisy chain stack of three.  we lost two-three 3com switches and now we have lost two dlink poe switches in last 4 months.  It was different switches in the stack..we reset etc plug them in elsewhere and same result...any expert advice in trouble shooting...
