I have 6 new sg500x-48mp in a stack. Network connectivity seems to be functioning normally. I've noticed that a few hours after bringing them online in a live environment that all the link lights on every port that has a connection, across every switch in stack, are blinking very fast in unison. Activity lights not blinking at all on any port. Is this normal light patterns for cisco switches?

Hi,
It looks like you have a loop. If this is PoE switch then left LED indicates activity and right port LED PoE connected device.
what can you see in logs?
what is the boot code and firmware?
Regards,
Aleksandra

They are POE switches. Thanks for correct info on the light indicators. Only thing I see in logs is a few random ports dropping connectivity then immediately reconnecting. Cisco support syas thei is from green ethernet function. Firmware is 1.4.0.88, boot code is 1.4.0.02
