About this communications card The Apple Ethernet CS Thin Coax Card expands the communications capabilities of models of Macintosh computers that have a communications slot (CS). The card is designed for networks that conform to the IEEE 802.3 standard for Ethernet. To connect to an Ethernet network, you must also install EtherTalk software, which is included with the card.
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. T-connector removed from card Thin coax port 2.
5. Follow the directions that came with your computer and replace the back panel or lid, and reattach any cables you removed earlier. 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. IMPORTANT Connecting your computer to the network will temporarily disrupt services to other users, so work quickly to restore the network.
. Lock the free end of the new cable to the T-connector on the other computer. Port on card 9. If you are adding your computer somewhere in the middle of the network, lock the unattached network cable to your T-connector. Otherwise, lock a terminator to your T-connector. The T-connector locks the network cable (and terminator, if needed) to your card. This restores network services for other users. 10. Attach your T-connector to the port on your card. It may help to use two hands.
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. Changing your AppleTalk zone If you need to change zones in the future, just follow the steps described in the previous section. Remember, when you click the EtherTalk icon in the Network control panel, you see the list of available zones from which to choose.
Troubleshooting Following are guidelines for handling common problems. If these suggestions don’t help you fix the problem, contact your network administrator. IMPORTANT The first step in troubleshooting any problem with your network connection is to check each of the following items. ■ The computer’s power is on. ■ The card is installed correctly. ■ The T-connector is locked to your card. ■ The network cable is in good condition and locked to the T-connector.
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. (If the Chooser is open, close and reopen it.) If you can access some services but can’t access a particular service (printing, for example), the device providing that service might be located in a different AppleTalk zone, or it might be malfunctioning, switched off, or disconnected from the network.
