    Introducing the Terminal Server 720 Product Prerequisites The Terminal Server 720 processor module and associated I/O modules can be ordered as part of a Network 9000 chassis configuration, or can be added separately to an installed Network 9000 unit. Each Terminal Server 720 processor module requires one Network 9000 chassis processor module slot.

  • Page 11: Parameter Storage And Loading

    (refer to the Guide to Managing Network 9000 Devices and Power Supplies for more information). The Terminal Server 720 is configured at the factory to store parameters locally on a flash memory card, if one is available, on the memory card of another unit in the hub acting as a parameter server, or remotely in a file at any properly configured parameter server.

    Network 9000 processor or I/O module, simply locate an empty slot in the Network 9000 chassis and use the same procedure to install the Terminal Server 720 processor and I/O modules. (Slot 1 cannot be used for a Terminal Server 720.) If you have not previously installed a processor and I/O module in the chassis, refer to the instructions contained in Chapter 4 of the guide Installing the Network 9000 Chassis.

  • Page 14: Install The Memory Card - If Available

    Installation Notes Install the Memory Card - If Available If the Terminal Server 720 is equipped with a memory card, insert the memory card into the card slot on the front of the unit. Xyplex recommends that you wear the grounded wrist strap, supplied with the Network 9000 chassis when you insert the card.

  • Page 15: Initialize The Terminal Server 720

    When you apply power to the Network 9000 Chassis, all modules in the chassis, including Terminal Server 720 units initialize themselves and begin to try to load software and operational parameters. If you have installed the Terminal Server 720 into an already functional Network 9000 Hub, you may need to reset the unit manually, as described below.
  • Page 16 Installation Notes To reset the terminal server manually, follow these steps: 1. Make a simple "tool" from an ordinary paper clip by bending one end outward. You need this tool to press the RESET switch located behind the terminal server's front panel.

    To connect the port to a DCE device (such as a modem), straight-through wiring is required. In the standard Xyplex-supplied modular cabling options, listed in section 3.3.8, signals are directed to the correct pins in the adaptor (for example, the crossover is made in the DROP adaptor, so that only one type of six-wire cable needs to be used) If you wish to make your own cables, you must construct the cable with the appropriate wiring scheme.

  • Page 87 Troubleshooting Possible Solutions: The Terminal Server 720 generates several messages during the load process, which can help you resolve loading problems. To see the messages, press RETURN several times at a terminal connected to a serial port, when the unit begins the loading process.

    Troubleshooting D.11 Troubleshooting TFTP Problems Use the following procedure to determine if TFTP is properly configured and running at the UNIX host: To verify that TFTP is properly running at the load server, you will use TFTP to get a file from the TFTP home directory.

  • Page 98: Troubleshooting Tftp Directory Or File Problems

    Troubleshooting If there is no entry for tftp in the /etc/inetd.conf file, add one. If there is an entry, but it begins with the comment character, remove the character. If there is an entry that does not begin with the comment character, the most likely problem is with the location, file protection or file ownership for the directory which contains the load images and parameter files.
  • Page 99 Troubleshooting File Ownership It is also important to understand the file ownership requirements for files that will be loaded via TFTP. Typically, TFTP implementations require that all files in the TFTP home directory have the same owner as the TFTP daemon (tftpd) in order for TFTP to have access to the files. For example, while many implementations require the files to be owned by root, on Sun Workstations the default owner is the special user id "nobody (-2 -2)".
