Troubleshooting
This chapter contains information to help resolving issues. If
the Industrial Fast Ethernet Switch is not functioning properly,
make sure the device was set up according to instructions in
this manual.
The Link LED is not light
Solution:
Check the cable connection of the Industrial Fast Ethernet
Switch.
Performance is bad
Solution:
Check the speed duplex mode of the partner device. The
Industrial Fast Ethernet Switch is operating at Auto-negotiation

the performance will become bad.

Solution:
Check that the attached device is not set to dedicate full

change duplex modes. Auto-negotiation may not recognize
this type of full-duplex setting.
Why does the Industrial Fast Ethernet Switch not connect
to the network?
Solution:
Check every port LED on the Industrial Fast Ethernet Switch.
Try another port on the Industrial Fast Ethernet Switch to
make sure the cable is installed properly while making sure the
cable is the right type
Turn off the power and turn on the power again after waiting
for awhile.
