Hardware Problems and Solutions (Continued)
Possible Cause
There is no link integrity.
Heavy traffic can cause the
network LED to blink so
rapidly that it appears to be
solidly lit.
However, if packets cannot
be passed, you might have
an incorrectly cabled
network.
If the PortMaster is not
receiving, or sending
traffic, the network LED is
not lit.
If packets cannot be
passed, the network might
be cabled incorrectly.
Refer to the solution
column.
Solution
Verify that DIP switches 4 and 5 are
up and that you have a working
10BaseT cable properly connected to
the PortMaster and to the hub. Turn
the power off and on to activate the
DIP switch setting.
