Downloading a new image involves the following steps:
• Load the new image onto a TFTP server on your network (if you will be using TFTP).

Load the new image onto a PC (if you will be using XMODEM).
• Download the new image to the switch using the following command:
download image [<hostname> | <ipaddress>] <filename> {primary | secondary}

filename
