Troubleshooting
This chapter provides information about troubleshooting the NETGEAR Model SW510 and
Model SW518 Ethernet switches.
LEDs
Verify that all other system components are functioning properly. There may be a defective adapter
card, cable, or port. Check for defects and replace the defective component.
If the Link LED does not light up when a device is connected to its corresponding UTP port, check
that both the switch and the connected device are powered on. When connecting devices to the
switch with twisted pair cable, make sure that the cable length does not exceed 100 meters. Refer
to
Chapter 4,
"Installation," and
Appendix C, "Ethernet and Cabling
Guidelines," for additional
information on twisted pair or straight-through cable use.
HDX/FDX/AUTO Duplex Toggle Switches
The factory setting for the duplex toggle switches on the 10 Mbps ports is half-duplex (HDX)
mode, and the factory setting for the duplex toggle switches on the 10/100 Mbps ports is
auto-duplex (AUTO) mode.
If performance degradation is a problem or if file transfer is slow, make sure that the half- or
full-duplex setting of the NETGEAR switch and the connected device are the same. When
connecting the switch to a repeater or hub, the 10 Mbps port on the switch must be set to
half-duplex (HDX) mode and the 10/100 Mbps port must be set to auto-duplex (AUTO) mode.
For instructions on setting the duplex toggle switches, refer to
"Connecting Devices to the
Switch"
