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 lt gt 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 lt A gt and then Y administrator will then be prompted for a valid administrator username and password see Fig 3 The factory administrator login settings are NETWORK TECHNOLOGIES INC e default use
