• 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.
Auto-Negotiation:
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 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 fiber gigabit ports negotiate speed, duplex mode, and flow control, provided that
the attached device supports auto-negotiation.
