Download interruptions. In most cases, if a power failure or other cause interrupts a flash image download, the switch reboots with the image previously stored in primary flash. In the unlikely event that the primary image is corrupted, as a result of an interruption, the switch will reboot from secondary flash and you can either copy the secondary image into primary or download another image to primary from an external source.
