Diagnosing transceiver modules
The switch provides the alarm function and digital diagnosis function for transceiver modules. When a
transceiver module fails or is not operating normally, you can check the alarms present on the transceiver
module to identify the fault source or examine the key parameters monitored by the digital diagnosis
function, including the temperature, voltage, laser bias current, TX power, and RX power.
To diagnose transceiver modules, execute the following command in any view:
Task Command Remarks
