Good day
I have a quick question well maybe not so quick but I have a layer 1 switch, a Nexus 3550-F this morning it was unreachable
but the odd thing is I was able to ssh to the switch. When I logged onto the switch we see the following error message:
*Error Message from CLI*

After power cycling it and rebooting via the CLI it appears to be ok now. Before we did all that noticed the following
Does this mean that the Module is flakily or about to die?
