TPPIL: If this LED is off, communication does not occur.
It is likely that the Ethernet board is not
connected with the hub normally. The LED does
not light also when the power to the hub is off. It
remains to be on when the Ethernet board is
connected to the hub normally.
COLLED: This LED lights frequently if Ethernet
communication traffic (amount of
communication) is heavy or noise in the
surrounding is high.
