    NDS/6000 Connectors

    The front panel of the NDS/6000 provides 1,2 or 16 DB-9 serial ports, with its number by each connector. Each serial port connector has an associated LED, also numbered, that signals normal operation or error conditions. A larger status LED on the lower right indicates the overall status of the port server. A reset button is provided. The hardware reset button reboots the port server, restarting it as if it had been powered off and back on, putting the unit into operating mode. The reset button also allows restoration of the default configuration to the unit.

    Configuring the NDS/6000 IP Addresses

    The NDS/6000 provides flexibility in assigning the necessary IP address. You can assign the IP address using one of five methods:

    • If you are using Windows, you can install and use the NativeCOM software, setting the IP address as part of the configuration process. The NativeCOM software is provided free of charge with your Systech port server.
    • directly assign the address on the RCS/6000 via terminal
    • assign the IP address using ARP on a host
    • assign the IP address using a BOOTP server allow a DHCP server to assign the IP address

    Session settings

    When the NDS/6000 is booted, the configuration information that defines the operation of the NDS/6000 during the session (the active configuration) is loaded into memory from the current configuration database in flash memory. You can change any configuration setting in the active configuration. In addition, you can save the active configuration into the current configuration database (in flash memory) so that the changed settings will be available after reboot/restart.

    When the NDS/6000 is delivered, the current configuration database contains factory default settings. In addition, a factory default configuration database (a copy of the current configuration database) is stored in flash memory. The factory default configuration database is stored as a backup configuration which can be restored into the current configuration database if necessary. If the NDS/6000 encounters an error condition while loading the current configuration database into the active configuration, it will load the factory default configuration database into the active configuration instead, in order to complete the boot. The status LED on the back panel will flash alternately yellow and green to indicate that a problem occurred and the factory default configuration was loaded.

    Changing Settings

    The configuration settings can be changed:

    • using a web browser to connect to the IP address of the NDS/6000; or
    • for Windows users, using the NativeCOM port redirector software developed by Systech and provided free of charge with the NDS/6000.

     

    At any point, you can restore the factory default configuration settings.

    Two reset buttons are provided, one to reset the hardware and one to reset the software. The hardware reset button reboots the port server, restarting it as if it had been powered off and back on, putting the unit into operating mode. The software reset button accesses the firmware monitor, but does not reboot. When the server enters the firmware monitor, operation is suspended and all active sessions are ended. The firmware monitor allows you to load new software into the port server, perform maintenance or troubleshooting functions, make a bootp request, etc.
