Diagnosing pluggable transceivers
The system outputs alarm information for you to diagnose and troubleshoot faults of pluggable
transceivers. Optical transceivers customized by H3C also support the digital diagnosis function, which
monitors the key parameters of a transceiver, such as temperature, voltage, laser bias current, TX
power, and RX power. When these parameters are abnormal, you can take corresponding measures
to prevent transceiver faults.
Follow these steps to diagnose pluggable transceivers:
