We have an issue where switches are failing weekly in a switch closet. In the past month we have gone through several 3750G switches and a couple 4510s. The power supplies have eventually made a popping noise and had to be replaced. on the 4510s we've tried two chassis and gone through several power supplies.
The switches have been behind UPS systems so should be receiving conditioned power.
Could load from the PoE devices really be causing this? I wouldn't think it's power since they are behind a UPS.
Any ideas on how to tackle this issue? We're going through switches like crazy...
Thanks
Sean
