required for default setting). When system prompt shows “Gateway>”, it means that the user has
successfully entered the User mode.
For security reasons, it is strongly recommended that you add a new login username and
password using User command in Configuration mode. When you create your own login
username and password, you can delete the default username (admin) to prevent unauthorized
accesses.
Enable Mode Password
Enable mode is password-protected. When you try to enter Enable mode, a password prompt will
appear to request the user to provide the legitimate passwords. Enable mode password is the
same as the one entered after login password prompt. By default, no password is required.
Therefore, press
Enter
key in password prompt.
Forgot Your Login Username & Password
If you forgot 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 Gateway, 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 Gateway for use when
you gain access again to the device.
2.3 User Mode
In User mode, only a limited set of commands are provided. Please note that in User mode, you
have no authority to configure advanced settings. You need to enter Enable mode and
Configuration mode to set up advanced functions of the Gateway. For a list of commands available
in User mode, enter the question mark (?) or “help” command after the system prompt displays
