LED Color Status Meaning
ACTIVITY Green ON The port is receiving data.
OFF The port is not receiving data.
LINK Green ON A connection exists between the port and
the end node.
OFF There is no connection between the port and
the end node.
PARTITION Amber ON The port is partitioned because of excessive
collisions (more than 127 consecutive
collisions) or because long packets (longer
than 5 milliseconds) are being sent over the
network.
If a port is partitioned, it is automatically
reconnected to the network when the
problem no longer exists.
OFF The port is not partitioned.
