3Com Switch - Lost Password Recovery

http://www.tek-tips.com/viewthread.cfm?qid=1181703&page=4

Hi, I spent a good few days trying to recover a lost password on one of our 3Com switches, i tried every backdoor i could find but to no avail. I finally found an answer... on the 3Com website.. log into the switch via hyperterminal and a com cable using the username and password "recover", it will then give you 30 seconds to pull the power. Once you stick the power back in and log on to the switch again, it will ask you for a new password.I'm not sure if this will work on all switches or just newer ones, but it's always worth a try.
