Network Technologies ST-NXM-U-HD manual OSD Control, Enabling The Security Feature

OSD Control

OSD Control

OSD superimposes a menu system on the user’s video screen with a list of all connected CPUs. OSD allows CPUs to be named (with up to 12 character names). OSD then allows selection of CPUs by that name. Connected CPUs can be listed by name or by port number. OSD Search Mode enables the user to type in the first few characters of the CPU's name and the OSD will locate it. HELP screens assist with all OSD functions.

Security Feature

The security feature in the OSD control of the ST-nXm-U-HD switch enables an administrator to control access to CPU ports for each user. Up to 63 users can be created. These users have controlled access to any CPU. Only the administrator can activate or deactivate the security features on each user port. Finally, the administrator can set a maximum idle time value after which the current user will be logged out and the login screen displayed again. This time out does not function while the OSD is active. The current security status, idle time out, and scan dwell time are all saved and will be restored whenever power to the switch is cycled OFF, then ON. To reset the administrator’s password call NTI and have the device serial number of the ST-nXm- U-HD switch available.

Enabling The Security Feature

To enable the security feature the administrator must first enter Command Mode from the keyboard using the <Ctrl> + <`> (accent key). The OSD menu will automatically appear on the monitor. This provides a visual way to control the ST-nXm-U-HD switch using the keyboard and mouse.

The administrator will activate security when logging in by typing <Ctrl> + <M> , then <A>, and then <Y>. The administrator will then be prompted for a valid administrator username and password (see Fig. 3).

The factory administrator login settings are:

•default user name = ADMINISTRATOR

•default password = ADMINISTRATOR

NOTE: The username for the administrator cannot be changed from "ADMINISTRATOR".

Once logged-in, follow the instructions on pages 9 and 10 for setting up users and changing the password. Once the password is setup, if it is lost or forgotten the administrator will have to contact NTI for assistance on clearing the password and set it up again. The administrator can setup each of the users and the limitations of their use of the individual CPUs within the Administration Mode.

When a standard user powers up the system a security screen may appear as setup by the administrator. The user will need to login to the system by following the instructions on page 8 for the USER LOGIN. If the user does not know the appropriate user name and password (setup by the administrator), contact the system administrator for this information. Once logged-in a user can follow the Command Mode functions described on page 11 to control the system of CPUs within the limitations as determined by the administrator.
