NETGEAR Managed Switch Additional Troubleshooting Suggestions If the suggestions in Table 3 do not resolve your problem, refer to the troubleshooting suggestions in this section. • Network adapter cards: Make sure that the network adapter cards installed in the computers are in working condition and the software driver has been installed. • Configuration: If problems occur after you change the network configuration, restore the original connections. Then find the problem by making the changes, one step at a time. Make sure that cable distances, repeater limits, and other physical aspects of the installation do not exceed the Ethernet limitations. • Switch integrity: You can verify the integrity of the switch by resetting the switch. To reset the switch, use the Tools > Reset command, or remove AC power from the switch and then reapply AC power. If the problem continues, contact NETGEAR technical support. • Autonegotiation: The copper 10/100/1000 Mbps ports negotiate the correct duplex mode and speed if the device at the other end of the link supports autonegotiation. If the device does not support autonegotiation, the switch determines only the speed correctly and the duplex mode defaults to half-duplex. The fiber gigabit ports negotiate speed, duplex mode, and flow control if the attached device supports autonegotiation. Troubleshooting 25
