Hello Hasan,

When a switch reboots and shows this type of output it needs to be inspected further. Please open a service request and attach the following outputs:

show tech
show log messages nvram

We will also need the core dump files to analyze what may have caused the crash. In order to get these see the following article:

How to upload debug information to a TFTP server

Please also upload any syslog messages if there is a syslog configured and note anything that may have been going on prior to the crash with regard to changes, heavy traffic, etc...
