Configuration
5.5. User Accounts
Prior to accessing command mode or establishing a Telnet Direct Connection, you will
be prompted to enter a username (login) and password. The username and password
entered at login determine which port(s) you will be allowed to connect and what type of
commands you will be allowed to execute. Each username / password combination is
defined within a "user account."
The RSM allows up to 128 user accounts; each account includes a username,
password, security level, port access rights, and an optional callback number.
5.5.1. Supervisor Access
In order to protect access to important command functions, the RSM allows you to
enable or disable Supervisor commands for specific accounts. Accounts that have
Supervisor Access enabled, will be allowed access to all configuration menus, review all
status screens, and connect to any RSM RS232 port.
When Supervisor Access is disabled, the account will be blocked from changing
configuration parameters, access to status screens will be restricted, and the user will
only be able to connect to ports specifically allowed by that account.
Note that in the default state, the RSM includes one predefined user account that
provides access to Supervisor commands and allows connections with any RSM RS232
port. The default username for this account is "super" (lowercase, no quotation marks),
and the password for the account is also "super".
Notes:
• In order to ensure security, it is recommended that when initially setting up
the unit, you should either change the username and password for the default
"super" user account, or preferably, a new user account with Supervisor
access should be created, and the "super" account should then be deleted.
• If the RSM is reset to default parameters, all user accounts will be cleared,
and the default "super" account will be restored.
• If Supervisor commands are disabled at a given port, then accounts that
permit Supervisor commands will not be able to access command mode via
that port.
In most cases, a password with Supervisor Access can be entered at any port, allowing
the user to invoke Supervisor level commands. However, if you wish to completely
deny a specific port’s access to Supervisor commands (even with a password that
normally permits them), the Port Parameters menus can disable Supervisor commands
at ports 3 and above, and the Network Port. The Supervisor Mode cannot be disabled
at Ports 1 and 2 (the System Setup Ports.) For a summary of commands and status
screens available to Supervisors and non-Supervisors, please refer to Section 13.
5.5.2. Port Access
Each account can be granted access to a different selection of ports. Accounts with
Supervisor access are always allowed to establish connections with all ports, but
accounts without Supervisor Access can be restricted to a specific port or group of
ports. Note also, that several accounts can be allowed access to the same port.
