Netgear GS716Tv3 – ProSAFE 16-Port Gigabit Managed Switch ハードウェアマニュアル

If the suggestions in Troubleshooting Chart do not resolve the problem, refer to the 
troubleshooting suggestions in this section.

Ensure the network adapter cards installed in the computers are in working condition and the 
software driver has been installed.

If problems occur after altering the network configuration, restore the original connections 
and determine the problem by implementing the new changes, one step at a time. Ensure 
that cable distances, repeater limits, and other physical aspects of the installation do not 
exceed the Ethernet limitations.

If required, verify the integrity of the switch by resetting the switch. To reset the switch, 
remove the AC power from the switch and then reapply AC power. If the problem continues, 
contact NETGEAR technical support. In North America, call 1-888-NETGEAR. If you are 
outside of North America, please refer to the support information card included with your 
product.

The RJ-45 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 gigabit port on the Gigabit module negotiates speed, duplex mode, and flow control, 
provided that the attached device supports auto-negotiation.
