One of Cisco 4507 switch got a continuous reboot problem. It just got super engine replaced in the slot 3. During power on process, the console screen shows a rebooting cycle in the following output.
It is obviously the reboot is caused by missing or corrupt image file. Also it may relate to an incorrect boot image is specified when setting up the boot variable, which prevents the booting of the system image.
The solution is pretty simple as well. Find out correct IOS file in system and set it as boot IOS.
