Chapter 4 Management from a Terminal Vmux-2100 Installation and Operation Manual
4-2 Preparing for the Control Session
Initiating a Control Session
Vmux-2100 supports two default terminal rates:
• 115.2 kbps, for 20–30 seconds after the power-up, until the boot sequence is
completed. Supervisory terminal connection may be required at this stage for
software downloading purpose.
• 9.6 kbps, during normal operation.
To initiate a control session:
1. Connect the terminal cable to the CONTROL connector of Vmux-2100.
2. Turn the control terminal on.
3. Configure the terminal to the default communication parameters: 9.6 kbps,
one start bit, eight data bits, no parity, one stop bit, no flow control, VT100
emulation.
You are now ready to start a control session.
Levels of Security
Vmux-2100 supports a four-level security and user authentication system:
• Administrator – Allowed to configure all the parameters of Vmux-2100.
• Operator – Allowed to perform all operations in the system, except for user
administration (adding/deleting users, changing user definitions).
• Technician – Allowed to test Vmux-2100 and monitor its operation (for
example, monitoring alarms).
• Monitor – Allowed to monitor the Vmux-2100 operation.
The maximum number of the users supported by Vmux-2100 is 20. When
managing Vmux-2100 over Telnet, up to five simultaneous management are
permitted. Only one administrator is allowed to enter the management session at a
time.
Vmux-2100 displays the management menus in accordance with a user’s access
rights. For example, configuration screens dealing with the unit configurations are
not available for the users, who logged in as technicians or monitors.
Default Security Configuration
Vmux-2100 is supplied with one administrator account:
• User name: admin
• Password: 12345.
When the first management session is initiated, it is recommended to create a new
administrator account, and delete the default one.
If the password is lost, consult your local RAD distributor.
