I recently purchased a Catalyst 2822 to learn IOS, except it doesn't work out of the box like a brand new switch might. I am wondering if I have to access IOS through the console on the back. If this is the case I would just buy a regular serial cable and open up hyperterminal to set all of the settings. Also, I don't see anywhere to download IOS by flash memory. Is there some way I could totally reset it?
