Additional Troubleshooting Suggestions

If the suggestions in Table 3-1
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 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. See the Support Information
Card that shipped with your product.
• Auto-Negotiation
The 10/100/1000 Mbps ports negotiate the correct duplex mode and speed if the device at the
other end of the link supports auto-negotiation. If the device does not support auto-negotiation,
the switch only determines the speed correctly and the duplex mode defaults to half-duplex.
The gigabit port on the gigabit module negotiates speed, duplex mode, and flow control, provided
that the attached device supports auto-negotiation.
