GS748T Smart Switch Hardware Installation Guide 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. If you are outside of North America, please refer to the support information card included with your product. Auto-Negotiation The RJ-45 ports negotiate the correct duplex mode, speed, and flow control if the device at the other end of the link supports auto negotiation. If the device does not support auto negotiation, the switch determines only the speed correctly, and the duplex mode defaults to half-duplex. Appendix A: Troubleshooting | 31
