5.1. System Mode and User Mode
In order to restrict access to sensitive command functions, the RPC-4850-8N
features two operating modes; System Mode and User Mode.
• System Mode: Allows access to all conﬁguration menus, switching
functions, reboot functions and status screens. The System Mode Status
Screens show On/Off conditions for all switched circuits, and lists all
currently deﬁned system parameters.
• User Mode: Allows access to switching and reboot commands, but
does not allow access to conﬁguration functions. Users may only issue
commands to, or view status of the circuits that are speciﬁcally allowed
by their password.
The RPC will display a password prompt when the unit is contacted via
the Console Port or Network Port. The password entered at this prompt
determines whether the unit will start-up in System Mode or User Mode. If
the System Password is entered, the System Mode will be active. If a Circuit
Password is entered, the User Mode will be active. The System Password
is deﬁned via the General Parameters menu (Section 5.3.1), and the Circuit
Passwords are deﬁned via the Circuit Parameters Menus (Section 5.3.3.)
• If you wish to restrict access to conﬁguration menus, you must
deﬁne the System Password. If the System Password is not deﬁned,
the RPC will always start-up in System Mode, allowing unprotected
access to conﬁguration and switching functions.
• If the System Password is not deﬁned, the Password Prompt will not
be displayed when you access the RPC via the Text Interface. The
prompt will always be displayed when the RPC is contacted via the
Web Browser Interface.
• When the RPC is contacted via Network, the password prompt will
also include a ﬁeld for the user name. If you have not deﬁned a user
name, then you may leave this ﬁeld blank, and only the password
is required to gain access to the unit. The user name prompt is not
displayed when the unit is contacted via the Text Interface.
