FULL/COL LED

A collision occurs when two stations within a collision domain attempt to
transmit data at the same time. Intermittent flashing amber of the collision
LED is normal; the contending adapters resolve each collision by means of a
wait-then-retransmit algorithm. Frequency of collisions is an indicator of
heavy traffic on the network.
If the FULL/COL LED lights amber, means the port is under Full-Duplex
operation or dark for Half-Duplex mode.
