Troubleshooting
This chapter provides information about troubleshooting the NETGEAR Model FS508 Fast
Ethernet switch.
LEDs
If the Link LED does not light up after making a connection, 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, “Cabling Guidelines ,” for additional information on
crossover twisted pair or straight-through cable use.
Verify that all other system components are functioning properly. If any component fails to
function, contact your NETGEAR distributor for assistance.
FDX/AUTO Duplex Toggle Switches
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 10/100 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 ”
on page 4-4 .
