If command is ran and no output is shown, it means that the equipment was powered off and powered on again or it never rebooted after last boot. On the sample above, the "reset by calling reboot" information means that the equipment was rebooted due the command "REBOOT".

Unfortunately, other reboot reasons couldn´t be identified, since this test ran in a laboratory and other reboot conditions were not possible to be reproduced.
