FS728TP Hardware Installation Guide
Additional Troubleshooting Suggestions
If the suggestions in Troubleshooting Chart do not resolve the problem, refer to the
troubleshooting suggestions in this section.
Network Adapter Cards
Ensure 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 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.
Switch Integrity
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.
Auto-Negotiation
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 negotiates speed, duplex mode, and flow control, provided that the attached
device supports auto-negotiation.
