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. - Page 9 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.

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.

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. -
Page 16: Network Adapter Card Drivers
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. -

AT-1720 conforms to the Packet Driver specification AT1700.COM developed by FTP Software. It can be used for implementations of TCP/IP such as PC/TCP, concurrent with other protocol stacks. Although the Allied Telesyn drivers support multiple Note protocol stacks, it is important to have only one stack of a given type resident. -
Page 22: Cabling
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. - Page 23 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.

Maximum segment length is 1000 meters (3279 ft.) for FOIRL and 2000 meters (6558 ft.) for 10BASE-FL. -

These transceivers are frequently used on a thicknet backbone. In Figure 8, you see a transceiver installed directly on the AUI port.

Page 30: Communication Status Indicators
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. -
Page 31: Troubleshooting
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. -
Page 32: Experiment With Possible Solutions
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. -
