ProSAFE 8-Port Gigabit Ethernet Easy-Mount Switch GS408EPP

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 resetting it. To reset the
switch, disconnect the AC power from the switch and then reconnect the AC power. If the
problem continues, contact NETGEAR technical support. For more information, visit the
support website at support.netgear.com.
• 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.
