GS700TR Series Hardware Installation Guide Table A-1. Troubleshooting Chart Symptom Cause Solution A segment or device is not recognized as part of the network. One or more devices are not properly connected, or cabling does not meet Ethernet guidelines. Verify that the cabling is correct. Ensure all connectors are securely positioned in the required ports. Equipment may have been accidentally disconnected. ACT LED is flashing continuously on all connected ports and the network is disabled. A network loop (redundant path) has been created. Break the loop by ensuring that there is only one path from any networked device to any other networked device. Additional Troubleshooting Suggestions If the suggestions in Troubleshooting Chart do not resolve the problem, refer to the troubleshooting suggestions in this section. Network Adapter Cards Ensure the network adapter cards installed in the PCs are in working condition and the software driver has been installed. Configuration If problems occur after altering the network configuration, restore the original connections and determine the problem by implementing the new changes, one step at a time. Ensure that cable distances, repeater limits, and other physical aspects of the installation do not exceed the Ethernet limitations. Switch Integrity If required, verify the integrity of the switch by resetting the switch. To reset the switch, remove the AC power from the switch and then reapply AC power. If the problem continues, contact NETGEAR technical support. In North America, call 1-888-NETGEAR.
