Hi Sarah, Thank you for sharing me that experiencie , I had that problem few times too , but with stand-alone switches . Also i got another similar issue before , we lost remote connection to a summit X460-48t that is located in a datacenter , the servers connected to it were working fine , no issues in the network , but we just couldn't have access to the switch remotely , so we had to go the datacenter and check the switch , there we found that problem with the console too that it wasn't responding . At the end we just reboot the switch and it fixed the issue. I opened a case with the GTAC support but there was any log in relation with the event , only the reboot log .
