COLLISION (Flashing Amber)—A momentary amber flash occurs when
a collision is detected on the port.
NO LINK (No Light)—If the link test function is not met by the 10BASE-T
device at the opposite end of the UTP segment, this LED will not
illuminate. This may occur if the workstation at the end of the segment is
turned OFF or if the UTP segment is disrupted or damaged.
SELF-TEST (Sequential Flashing Green)—This indicates the hub is
conducting a power-ON self-test. The test continues until one port is
connected (valid link) or the module is connected to the chassis backplane.
