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 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 resetting it. To
reset 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 Gigabit Ethernet ports negotiate speed, duplex mode, and flow control if the
attached device supports autonegotiation.
