About this communications card The Apple Ethernet CS Twisted-Pair Card expands the communications capabilities of models of Macintosh computers that have a communications slot (CS). The card is designed for an Ethernet network that uses IEEE 10BASE-T standard twisted-pair cable. To connect to an Ethernet network, you must also install EtherTalk software, which is included with the Twisted-Pair Card.
2. Remove the card from its antistatic bag. Installing and connecting your card 1. Follow the specific setup information that came with your Macintosh to open the back panel or lid, and locate the communications slot inside the computer. The material that comes with your Macintosh includes instructions to help you avoid damage to your computer’s components when installing the card. Be sure you’ve shut down and turned off the power to your computer before starting the installation.
4. Follow the directions that came with your computer and replace the back panel or lid, and reattach any cables you removed earlier. Card’s green LED lights up when there’s a good network connection. Depending on the model you have, you will need to slide the logic board back into place, remove the communications port cover, replace a back panel, replace a lid, and so forth. 5. Plug the twisted-pair cable from your network into the RJ-45 port on your card.
Installing EtherTalk software To install the correct version of EtherTalk software you need to use the Installer program on the Network Software Installer disk, version 1.4.2 or later, included with your card. For safety, make sure that the Installer disk is locked before you use it. To lock a disk, slide the tab on the back side so that the square hole is open. Open the disk to find the Installer.
2. Open the Installer program, review the Welcome screen, and click OK. 3. Make sure that the disk indicated on the Installer’s dialog box is your current startup disk, and click Install. 4. When you see a message reporting that the installation was successful, click Restart. Before you can use services on an Ethernet network, you need to select the EtherTalk network connection for your startup disk. The next section shows how.
Setting the Network control panel for EtherTalk A Macintosh computer’s network connection is preset for LocalTalk. To connect to an Ethernet network instead, you need to change the setting in the Network control panel. Follow these steps: 1. Choose Control Panels from the Apple () menu. 3. Click the EtherTalk connection to select it. A message asks you to confirm the change of network connections. You may have more network connection choices than those shown in the following figure.
5. If you see the following dialog box, click OK. If you don’t see a dialog box, skip to step 6. 6. Close the Network control panel. You are now ready to use services available on your Ethernet network. IMPORTANT You may notice that the green LED on your card flashes occasionally. This is normal. It indicates that the computer is sending information over the network.
Troubleshooting The first step in troubleshooting any problem with your network connection is to check that the card’s green LED light is on—if your card has an LED. When the computer sends information over the network, the LED flashes. If your card does not have an LED, you can’t use the LED in troubleshooting, but you can follow all the other guidelines for handling common problems. If the following suggestions don’t help you fix the problem, contact your network administrator.
If you can’t select EtherTalk in the Network control panel: Be sure that the network cable is properly attached and that the card’s green LED is on. If you are still unable to select EtherTalk, there may have been a problem with the network software installation. Reinstall your network software according to the instructions in this guide. If you don’t see network services listed in the Chooser: Make sure your network connection is okay. Open the Network control panel and click EtherTalk.
