and network connections. These polyswitches are not replaceable and will reset themselves if the condition that caused the fault returns to normal.
Rx Lights when the controller receives data from the network segment; there is an Rx LED for Ports 1 and 2.
Tx Lights when the controller transmits data to the network segment; there is an Tx LED for Ports 1 and 2.
Run Lights based on controller status. See Table AV.
Error Lights based on controller status. See Table AV.
