  • Page 9: System Description

    SCS1620 Product Manual 1.0 System Description The Lightwave Secure Console Server 1620 (SCS1620) is a fully customizable console server offering secure encryption and authentication. The SCS1620 is a compact solution for remote and local management of up to 16 devices with RS-232C compatible serial consoles.

  • Page 11: System Overview

    SCS1620 Product Manual 2.0 System Overview Typical Use The SCS1620 is often used to manage up to 16 serial devices (servers, routers, switches, etc.) where security is mandatory. Each attached device must have an RS-232C compatible serial console port. A User accesses the attached servers with keyboard commands from their local terminal, through a network connection, or through a dial-up connection.

  • Page 12: Modem

    FIFO buffer. This data may be viewed while the user is not directly interacting with the attached device. System Resource Information The SCS1620 is programmable using OS-level commands and options. The System Administrator (sysadmin) configures the product using a command-line interface or one of several prepared scripts, using UNIX / Linux commands.

  • Page 13: Installation

    Physical Installation The SCS1620 may be installed either in an EIA-standard 19-inch rack (1U tall) or as a desktop unit. For desktop use, four rubber feet are provided, and the rack mount brackets may be removed.

  • Page 14: Dc Input

    See Appendix D for specifications regarding the DC power source. Connecting a Terminal (Console) The TERMINAL port (a Console port) is used for local access to the SCS1620 and the attached devices. A dumb terminal or computer may be attached to the serial port if the port uses RS-232-C protocol and VT100 emulation is supported.

  • Page 15: Connecting To The Device Port

    Turn on the terminal or start your computer’s communication program. Connecting to the Device Port Any serial device that has a console port may be connected to the SCS1620 for consolidated remote administration. Device Ports are individually configurable (DEVICE_1 through DEVICE_16). The console port must support the RS-232-C interface.

  • Page 16: Connecting The Network Port

    Connecting the Modem Port An optional modem module is available for the SCS1620. The modem may be installed at the factory or can be ordered separately for later installation. SCS1620 modem module The SCS1620 modem is an analog modem supporting connection rates up to 38,400 baud.

  • Page 17: Power Manager Port

    Refer to Section 7 for Modem Installation instructions, if installing a modem into a working SCS1620 system. Power Manager Port The Power Manager port is configured as Device Port 17, and operates like the other DEVICE ports, except that its physical interface is a DB9F serial connector.

  • Page 18: Quick Start Set-Up

    Quick Start assumes the system is plugged in and turned on, and that you know the IP address that the SCS1620 must be set to in order to operate on your network, and that you are ready to connect to your network port.

  • Page 20: Method #2 - Quick Start Via Telnet

    SCS1620 via telnet commands. If you add a route to your workstation, you can use telnet to connect to the SCS1620, instead of the Terminal Port. The default IP address of the SCS1620 is 10.0.0.1, with a subnet mask of 255.0.0.0.

Connect the terminal port to a terminal device or computer using a terminal emulation program (refer to section 3.4 for instructions on connecting to the terminal port).

  • Page 22: Logging Out

    The sysadmin programming level is as close to 'root' as is required to administer the SCS1620, but it is not the most-senior root level. The root level is intentionally removed from the shell, however, it exists in the system and its password must be changed to protect from unauthorized access or changes.

  • Page 23: The Setup User Interface

    System The scripted programming session (setup Administrator logs into the SCS1620 for the first time. It is a text-based user interface, and requires VT100 terminal support using the keyboard (no mouse). At default values, SSH is not enabled (encryption keys have not been generated) so telnet is often used to initially access and configure the SCS1620.
