intermittent After the cabling has been installed, if the Link LED is not lit on
an active port, check the attached device and make sure that it
is powered on and there is a proper UTP connection at that
end. Also make sure that the proper cable is installed, and
check for miswired cable pairs or loose connectors.
If the Link LED is on intermittently, check the port termination at
both the switch and device ends. Check the crimp on the RJ-45
connectors.
Check that the length of the UTP cable from the switch to the
device does not exceed 328 feet (100 meters). Using cable test
equipment, check that the cable meets the specifications as
required by the 10BASE-T standard. Refer to Chapter C,
“Cabling Guidelines,” for information on cable specifications.
Make sure the network adapter card installed in the PC is in
working condition.
Make sure that there is power to both the switch and the
