Network Adapter Cards
Make sure 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 con- nections and determine the problem by implementing the new changes, one procedure 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
If required, verify the integrity of the switch by resetting the switch. Turn power to the switch off and then back on. If the problem continues and you have completed all the preceding diagnoses, contact your NETGEAR
Auto Negotiation
Each port will negotiate the correct duplex mode and speed, provided the link partner supports auto negotiation. If the link partner does not support auto negotiation, only the speed will be determined correctly and the duplex mode will default to half.
