Cisco 9300 Reload

[JAISONTHOMAS]

Hi,

We have a stack of 4 X C9300-48UXM switches in one of our Hub rooms. They are all on version 17.12.04.

All these switches got reloaded yesterday. All these switches are connected to the main power supply. We got it confirmed with the power company that there were no power disruptions.

Is anyone aware of any bugs associated with this issue?

Ok, so the entire stack is running off one power supply. 

The output shows there was  a power outage.  If all switches are reporting the same output "PowerOn" then the stack lost power.

                                               Well perhaps, but the situation looks different; therefore and for future follow up I recommend that you configure a common syslog server on all stacks (and all other cisco network equipment) , when devices got rebooted or started again for some reason, examining logs or last logging received at the syslog server may provide extra insights ,

   As @Leo Laohoo , stated the command show version will also include the reboot reason,

It's always a good idea to power the switches, or any other networking equipment, from an UPS which can mitigate situations like a small power fluctuation from the power company - a second is enough to restart your equipment, If you have a UPS dimensioned correctly, you can survive even a small power outage of several minutes.
