Installing the Bridging Converter DIP SWITCHES Negative Positive Ground Figure 9 Positive, Ground, and Negative Symbols Warning The power input must be provided from SELV source only, per IEC 60950. Do not connect to centralized DC battery bank. 3. Secure the power supply cable in the Restricted Access Area using multiple cable ties to minimize the chance of the connections being disturbed by casual contact with the wiring. Warning "Safety Hazard"- Check to see if there are any exposed copper strands coming from the installed wires. When this installation is done correctly there should be no exposed copper wire strands extending from the terminal block. Any exposed wiring can conduct harmful levels of electricity to persons touching the wires. . 16 4. Plug the power connector to the 12-50VDC receptacle connector in the rear of the converter, as shown in Figure 10. Figure 10 Connecting a Power Connector to the 12-50VDC Version Model AT-FS238a/x and AT-FS238b/x Series Installation Guide Note UL recognized wires of 22-gauge minimum should be provided by the installer. 5. With a 22-gauge wire-stripping tool, strip the three wires in the tray cable coming from the DC input power source to 8mm ± 1mm (0.31in.± 0.039in.), as shown in Figure 11 on page 21. Warning Do not strip more than the recommended amount of wire. Stripping more than the recommended amount can create a safety hazard by leaving exposed wire on the terminal block after installation. . 17 Figure 11 Stripped Wire 6. Connect the ground wire to the terminal marked with the ground symbol by inserting the wire into power connector that comes with the converter and tightening the connection with a flathead screwdriver, as shown in Figure 12. Warning When installing this equipment, always ensure that the frame ground connection is installed first and disconnected last. . 18 Figure 12 Connecting the Stripped Wire 7. Connect the negative feed wire to the terminal block marked (-). 8. Connect the positive feed wire to the terminal block marked (+). Installing the Bridging Converter 9. Connect the other end of the wires to the terminal block on the ATPWR237 power adapter. Note The terminal block on the AT-PWR237 does not have a connection for the ground feed wire. Warning "Safety Hazard"- Check to see if there are any exposed copper strands coming from the installed wires. When this installation is done correctly there should be no exposed copper wire strands extending from the terminal block. Any exposed wiring can conduct harmful levels of electricity to persons touching the wires. . 19 10. With the wires securely connected to both the input power connector in the rear of the unit and the terminal block on the power source, plug the other end of the power source to the power outlet. (Refer to “Technical Specifications” on page 27 for power requirements.) 11. Power ON the end-nodes. 12. Verify that the LNK LEDs for both the fiber optic port and the twisted pair port are green. If either LED is OFF, refer to “Troubleshooting” on page 25 for instructions. The bridging converter runs a series of self-diagnostic tests. Once the self tests are complete, the converter is ready for normal network operations. AT-FS238a/x and AT-FS238b/x Series Installation Guide Warranty Registration When you finish installing the product, you should register your product by completing the enclosed warranty card and sending it in. Chapter 3 Troubleshooting Follow the guidelines below to test and troubleshoot the installation in the event a problem occurs. Note Whenever the speed and/or duplex mode are changed during or after power ON, power OFF then power back ON the bridging converter to load the new configuration. If the PWR LED is OFF, do the following: . If the bridging converter is installed on a desktop, check to be sure that the power adapter is securely connected to a power outlet and that the power adapter cable is securely connected to the back of the bridging converter. . If the bridging converter is installed in an AT-MCR12 chassis, check that the unit is fully seated in the slot and the retaining screw is securely fastened. . Verify that the power outlet has power by connecting another device to it. . Try using another power adapter. If the LNK LED for the twisted pair port is OFF, do the following: . Check that the end-node connected to the port is powered ON and is operating properly. . Check that the twisted pair cable is securely connected to the twisted pair port on the bridging converter and on the end-node. . Check to be sure that the end-nodes connected to the bridging converter are operating at the same duplex mode. Troubleshooting . Make sure that the twisted pair cable does not exceed 100 meters (328 feet) and that you are using a Category 3 or better cable for 10Base-T operation or a Category 5 or better cable for 100Base-TX operation. If the LNK/ACT LED for the fiber optic port is OFF, do the following: . Verify that the end-node connected to the port is ON...
