Additional Troubleshooting Suggestions
If the suggestions in Table 3 on page 22 do not solve your problem, refer to the
troubleshooting suggestions in this section.
• Network adapter cards
Make sure that the network adapter cards installed in the PCs 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 connections, 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.
• Auto-nNegotiation:
If the device at the other end of the link supports auto-negotiation, the copper
10/100/1000 Mbps ports negotiate the correct duplex mode and speed. If the device does
not support auto-negotiation, the switch determines only the speed correctly, and the
duplex mode defaults to half-duplex. If the attached device supports auto-negotiation, the
fiber gigabit ports negotiate speed, duplex mode, and flow control.
