Rx/Tx Collision LED
blinking Blinking yellow Data collisions are normal on Ethernet networks and occur
when two or more computers transmit data on the network
simultaneously. Computers that caused the collision retry
transmission at different intervals until the transmission
succeeds. Excessive collisions can result when multiple
switches are connected and when many computers are
connected on the network. Incorrect cabling, connectors, wiring
techniques, and mismatched duplex operating mode settings
are other causes for excessive collisions.
When configured to
operate in full-duplex
mode, the port is
operating in half-duplex
mode FDX LED off The connected device may not be able to operate at
half-duplex or may not have the ability to signal the operating
mode. Verify that the connected device is operational.
