So about 2 months ago I have a Cisco WS-C3560G-24PS-S switch die on me. It was working then it just stopped. So I power cycled it. Fans turn on and the lights on the front turned on, then went off, but not much else happened, no boot and nothing from the console at all.
So I replaced it with a spare we had (exact same model), and everything was happy. The dead switch sat on my desk for about a week until I managed to get the time to call Cisco to see if they would replace it, and while I was on hold I decided to plug it in and remind myself of the issue. Lo and behold the damn thing started up just fine and was working 100%. I had Cisco replace it anyway, since I could not trust it.
Anyway, fast forward to today, and the replacement switch I put in two months ago has died as well. With the exact same symptoms. Plug it in, get the fans spinning, all the light turn on briefly and then turn off and no console data coming from the unit at all.
One switch failing like this is par for the course and nothing to ponder about, but 2 switches, having the exact same issue in such a short period of time? That leads me to think there is something else going in here, but I am at a complete loss as to what that could be.
Any suggestions on where I can look here? I'd like to be reasonably sure that this won't happen to a third switch I put in place.
