You’ll need to access the physical DB-9 serial console with a null serial cable. I found the defaults to work at 19200-8-N-1.
Once plugged in you’ll need to login to the console as the username “restore” with the password of “restoreDefaultPassword”. Here’s an example;
WS5100 login: cli User Access Verification Username: restore Password: restoreDefaultPasword WARNING: This will wipe out the configuration (except license key) and user data under "flash:/" and reboot the device Do you want to continue? (y/n): y
After the switch reboots you’ll need to use the default administrator username and password to log into the switch. They are username “admin” and password “Symbol”. Im my case it was admin/symbol but it could be admin/motorola.
Once this is done you can logon via serial using the cli user and then admin/which ever password worked and setup the switch.
Note that due to the age of these, web management cannot be done via https. You’ll need to load an old version of java and connect via http. I’ll try to cover that in another article.
If you’re good at the command line you’re set.
