Has anyone seen a Cisco switch's port LED's blink green all in unison. All 5 switches I have running are blinking in unison and then it does a port check and you can see it roll down the line by watching the LED's. I've unplugged every switch/hub I have on my LAN, no luck. I've also unplugged the power to all the 3750 switches to see if 1 in particular was at fault, no luck. I know it's not a loop because all the LED's are not amber. Anyone ever seen this happen before and might be able to point me in the right direction. Thanks!
