I've got a Cisco Switch SG500X-48P
and I download the firmware updates from the cisco web, the download is a .zip file with .ros and .rfb file inside.
So when i tried to upgrade the firmware send me the error "Copy: Illegal software format"
I tried to upgrade with the .ros, .rfb and the zip file but it doesn't work.
Can anybody help me to upgrade the firmware or tellme what it's te image file extension.
Thank you.
