Hi @Nurul Islam

Note: It's showing the reload reason for switch 2 which is master at the moment and we are having issue with switch 1

[Flavio Miranda]

 This is a good place to go when the switch reload.  This logs is not good as it is saying the reload reason was due the reload command, so,  it would be good look the same information but when the switch reload again by itself.

  If the switch with problem is another switch, it would be good do a console on it and see the logs.  Maybe remove it from the stack 

[Nurul Islam]

Sure, I will console into it and check...

And just to let you know it's a Stack of 2 switches and switch 2 is fine, it's only the switch 1 which is rebooting by itself...

 Interesting.   It suggest problems related to power supply or AC power  problem.

It is not cause by a crash. 

Therefore I can say that the switch has power source issues.
