Additional troubleshooting suggestions
If the suggestions in the troubleshooting chart do not resolve the problem, see the
following troubleshooting suggestions:
•
Network adapter cards: Make sure that the network adapters that are installed in
the computers are in working condition and the software driver was installed.
•
Configuration: If problems occur after you alter the network configuration, restore
the original connections and determine the problem by implementing the new
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: If necessary, verify the integrity of the switch by restarting it. To
restart the switch, disconnect the power from the switch and then reconnect the
power. If the problem continues, contact NETGEAR technical support. For more
information, visit the support website at netgear.com/support/.
•
Autonegotiation: The RJ-45 ports negotiate the correct duplex mode, speed, and
flow control 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 Ethernet ports negotiate speed, duplex mode, and flow control if the attached
device supports autonegotiation.
