Forgot Your Login Username & Password
If you forget your login username and password,
you can use the “reset button” on the front
panel to set all configurations back to factory defaults. Once you have performed system
reset to defaults, you can login with default username and password. Please note that if you
use this method to gain access to the Managed Switch, all configurations saved in Flash will
be lost. It is strongly recommended that a copy of configurations is backed up in your local
hard-drive or file server from time to time so that previously-configured settings can be
reloaded to the Managed Switch for use when you gain access again to the device.
