WARNING

Ensure that power to the switch remains uninterrupted while downloading an image
or a boot code file to the switch. If a power failure occurs while downloading a file,
the file contents in persistent memory are lost.

If a power outage occurs during boot code file download, the switch will not be
able to boot. Contact the Cisco Small Business Support Center for assistance.

If a power outage occurs during image download, the image will not load, but the
boot loader will continue to be operational. See

Firmware Recovery Over HTTP

for instructions on downloading a working image.
