FDX/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 FDX/COL light green which means the port is under full-duplex operation or
dark for half-duplex mode. The following table is a summary of Port LEDs.
