3Com Default Passwords


Welcome to the open-sez.me 3Com default passwords page.

Before you open a ticket with 3Com tech support, see if your device or software is in this list. Check the Access Method column to make sure your access method is correct, then try the given default username and password. For the defaults to work in your 3Com device or software, you may need to reset the device or reinstall the software, either of which could cause data loss, so be sure to have backups before you proceed! It's a best practice to have a regular backup schedule in place before disaster strikes!
