I have a stack of 6 3750's in my MDF. Additionally, I have 1 additional 3750 in an IDF on another floor, connected via fiber/SFP to a gig port on each end. When I initially connected the fiber in the IDF, it reset the entire 3750 stack, which bounced 150 phones on my main floor. Last week, the power went out on the other floor and when it came up, it bounced the whole main stack again. I didn't put it together until it happened again.
Anyone have any ideas why it would do this when I connect the IDF switch?
