X670-48x Ports - All LED went off

[showospf]

Hello all,

I currently have to X670-48x stacked with XOS 15.3.1.4 patch1-10 and recently we had an issue where most of the active LEDs went off and all ports went down at the same time. after restarting the switch, nothing changed all the ports remain down still. we had to reinsert all the SFPs (about 20) for ports to be active once more.

Is anyone aware of an issue with this model that could be causing this?

Thanks in advance.

Ok thank you guys for your feedback...we will try to get the switches up to the latest patch level and hopefully avoid this happening again.
