Chapter 2 Installation Summary of Installation Steps Installation of your Allied Telesyn network adapter card is simple and quick. Generally, the installation of one network adapter card with common software on PS/2 MCA bus or compatible workstations is mostly automated. This chapter also gives procedures for more complex installations. The following list of steps for the simplified Allied Telesyn network adapter card hardware/software installation is explained in greater detail later in the chapter. 1.
AT-1720 OS/Environment-Specific Installation Information Accurate and current network hardware and software installation information changes with every network software package, protocol stack or operating system. To respond quickly and accurately to these changes, we have included the latest installation information in a series of applications and OS specific readme files on the Allied Telesyn CardAssistant diskette. The file \READ.
Installation 1. Make sure the computer’s power is turned OFF. 2. Pick the card slot you wish to use. Follow the manufacturer’s instructions for adding a card. TIP: When installing the AT-1720FT temporarily remove the shields from the fiber-optics cable connectors to give the connectors more clearance. Do not turn ON your computer.
AT-1720 2. At the “Automatically configure the system? (Y/N)” prompt, answer N for no, and the Main Menu will appear. Do not answer Y here, or you will have to reset your computer to get back to this point. 3. Select the “Copy an option diskette” option, and follow the procedure to completion. 4. Remove the Allied Telesyn diskette from the floppy drive. Configuring the adapter card (auto-configure) 1. Verify that all floppy drives are empty if you followed Step 1a on page 7.
Installation 4. Scroll through the Change Configuration window to view all the configuration attributes of the Allied Telesyn AT-1720 adapter card. A list of those attributes and your choices is found in Table 1. 5. Change the configuration attributes as necessary. The configuration software does not allow you to set adapter card values that conflict with the rest of your system. 6.
AT-1720 Saving configuration to system partition 1. Boot your computer as in “Installing option files” Steps 1a or 1b, on page 7. 2. In the Main Menu, select the “Set Configuration” menu. 3. To backup the configuration you just completed, select “Set configuration,” and from that menu, select “Backup configuration.” When the backup is complete (a few seconds) press ENTER to accept the backup, F3 to go to the Main Menu, and F3 to exit.
Installation 3. CardAssistant is copied onto a hard drive when you install the driver for the adapter card. Once this is accomplished, you can type: path\setup17 where path\ is the optional drive and directory. 4. The Main Menu appears and you are ready to select one of the icons. Working with CardAssistant menus You can use either the keyboard or mouse to make menu selections.
AT-1720 The CardAssistant diagnostic routines test the board and the configuration for functional problems. The routines are: ❑ ❑ ❑ ❑ ❑ ❑ PC bus interface On-board RAM Interrupt test Internal loopback MAC address Boot ROM The diagnostic routines display whether the card passed each test. You can see if the board passes before connecting the computer to the network, and then confirm that it still passes after the network connector is plugged in. This method can help you isolate a problem.
Installation If more than one card is installed and configured in the host when you run CardAssistant, the configuration window displays a column of settings for each. You can tell which column is for which card by checking the node address. The node address displayed agrees with the label on the card itself. Boot ROM Socket The AT-1720 card is shipped with an unpopulated boot ROM socket. For a diskless workstation, the card needs a boot ROM to allow it to load the operating system over the network.
Chapter 3 Network Adapter Card Drivers Because user network environments are numerous, differing in network-management software, operating systems, and protocol stacks, a variety of adapter card drivers is necessary to operate an adapter card in a majority of environments. An ODI driver for NetWare running in DOS might be needed, or an NDIS driver for Windows for Workgroups or for LAN Manager running in OS/2, or a packet driver for PC/TCP in DOS.

Network Adapter Card Drivers Driver Installation The procedures for installing, binding or merging these drivers with the network software vary with the operating system type and version. For detailed instructions, refer to the LAN administration manuals for your network software. TIP: Network software manufacturers’ procedures and file structures are subject to change. This is why the adapter card manual can only provide general guidelines on installing drivers.
AT-1720 4. Complete the installation of the network software, and review all configuration files to verify that they match the card’s configuration. Updating a Novell IPX workstation to ODI Individual Novell IPX workstations on NetWare systems are frequently converted to Novell Open Data-Link Interface (ODI) workstations running on the same system. This conversion is typically made because Novell no longer supports the IPX specification, and has replaced it with the ODI specification.
Network Adapter Card Drivers 4. Exit the manufacturer’s configuration software. Note The word “Slot” in the following step, must be indented from the left margin under the Link Driver line by at least one space or one tab. 5. Open the ASCII file NET.CFG with a text editor and verify that the following lines are there: Link Driver AT17ODI Slot x where x corresponds to the computer’s card cage slot number. 6. The batch file, e. g., AUTOEXEC.
AT-1720 AT1700.COM conforms to the Packet Driver specification developed by FTP Software. It can be used for implementations of TCP/IP such as PC/TCP, concurrent with other protocol stacks. Note Although the Allied Telesyn drivers support multiple protocol stacks, it is important to have only one stack of a given type resident. For example, if you use the public domain IP protocol driver PROTMAN.SYS, you should not use another TCP/IP stack concurrently.
Chapter 4 Cabling For complete rules of cabling and for information useful in planning network configurations, see ISO/IEEE Publication 8802-3. The AT-1720T is for use with 10BASE-T segments, using an 8-wire (4-pair) RJ45 jack for the network cable, shown in Figure 1. Figure 1: AT-1720T UTP Port and RJ45 Connector Important 10BASE-T Cable Considerations A serious problem exists concerning identification of modular cable for 10BASE-T connections.
AT-1720 The identification problem is exaggerated by the fact that some suppliers have sold purportedly data-quality cables manufactured with voice-quality cabling. If any voice-quality cabling is used in a 10BASE-T network segment, data movement is slow, collision-prone or non-existent. To confuse the issue, the Link indicator on the interface will usually indicate a valid link in such a case.

Cabling Figure 3 shows where to locate pin 1. Figure 3: Pin 1 Orientation on an RJ45 Connector Pin 1 10BASE2 RG58/BNC Cabling In addition to an RJ45 connector, the AT-1720BT has a BNC connector for 10BASE2 standard thin Ethernet RG58 coaxial cable. The maximum segment length is 185 meters (606 ft.), and the minimum length between nodes is 0.5 meters (1.64 ft.).
AT-1720 Figure 5: Incorrectly Connected BNC for 10BASE2 10BASE-FL/FOIRL (Fiber Optic) Connection The AT-1720FT provides both an RJ45 for 10BASE-T Ethernet and ST-type transmit and receive connectors for 10BASE-FL (the current standard, backward compatible with FOIRL) or FOIRL Ethernet network segments. Maximum segment length is 1000 meters (3279 ft.) for FOIRL and 2000 meters (6558 ft.) for 10BASE-FL. (See Figure 6.) Warning Hazardous light emissions may exist in fiber optic systems.
Cabling Transmit Receive Figure 6: ST-Type Connector for FOIRL and 10BASE-FL Medium 10BASE5 (AUI) Connection The AT-1720AT offers both an RJ45 and an AUI port. (See Figure 7 and Figure 8.
AT-1720 Figure 8: AUI Connector for Direct Transceiver Connection In Figure 7, you see an AUI cable from a remote transceiver, such as the Allied Telesyn AT-100, AT-150, AT-200, AT-250, AT-270, AT-440 or AT-470. These transceivers are frequently used on a thicknet backbone. In Figure 8, you see a transceiver installed directly on the AUI port. Table 5 shows Allied Telesyn direct-connection micro transceivers available to interface the card with the medium of your choice.
Cabling If a transceiver is installed on an AT-1720, the setting of the SQE switch (heartbeat) is not important. Turning the SQE switch OFF or ON will not result in degradation or failure of network communication. Communication Status Indicators Table 6 shows the functions of the four status indicators located below the RJ45 receptacle.
Chapter 5 Troubleshooting A network is a complex combination of hardware and software, all of which must function for data communication to work. Problems are most likely to occur when the card is first being installed or when someone changes something in the network. A problem could be caused in your computer or in cabling or in many places elsewhere in the network.
AT-1720 Experiment with Possible Solutions The first rule of troubleshooting is to isolate the problem. As you experiment, vary only one factor at a time. Substitute known good equipment and see if the problem persists or is eliminated. ❑ Do not overlook the obvious—make sure the card is seated in the computer and that the cables and connectors are securely attached. ❑ If the link LED does not light with UTP or fiber optic media, make sure the cabling is intact and connected to a functioning network port.
Troubleshooting ❑ Update the adapter card driver for the new settings. (See your network software manual.) ❑ Replace Corrupted Network Software. Replacing corrupted network software 1. Temporarily move the files that refer to the adapter card driver and comment out references in your batch files. 2. Refer to your LAN administration manual for instructions on how to install your network software. Get Technical Support You can contact the dealer where you bought your AT-1720 for local assistance.
