Troubleshooting
This chapter provides information about troubleshooting the Model SW502 and Model SW507
switches.
Front Panel Indicators
The front panel indicators can assist you with identifying problems and monitors the Model SW502
and Model SW507 switches.
For UTP connection, if the Link LED does not light up after making a connection, there may be a
defective network adapter, cable, or port. Check for defects and replace the defective component. For
AUI or BNC network connection on the Model SW502 switch, the Link LED will not light until there
is data going through the port.
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. For devices connected to the switch
using twisted-pair cable, check that the cable length does not exceed 100 m. Refer to Chapter 3,
"Installation," for additional information on twisted-pair or straight-through cable use.
Use the diagnostic procedures described in Chapter 2 , "Physical Description," to verify that all other
system components are functioning properly. If any component fails the diagnostic test, contact your
NETGEAR distributor for assistance.
Half/Full Duplex Switch
The default setting for the Half/Full duplex switches is half-duplex. 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 any port on the switch to a repeater
or hub, the port on the switch must be set to half-duplex transmission.
