Troubleshooting

NETGEAR GS510TP Smart Switch

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 on the Gigabit module negotiates speed, duplex mode, and flow control,

provided that the attached device supports auto-negotiation.

A segment or device is

not recognized as part of

the network.

One or more devices are

not properly connected,

or cabling does not meet

Ethernet guidelines.

Verify that the cabling is correct. Ensure all

connectors are securely positioned in the required

ports. Equipment may have been accidentally

disconnected.

ACT LED is flashing

continuously on all

connected ports and the

network is disabled.

A network loop

(redundant path) has

been created.

Break the loop by ensuring that there is only one

path from any networked device to any other

networked device.
