Diagnosing Pluggable Transceivers; Displaying And Maintaining Device Management Configuration - H3C S5120-EI Series Operation Manual

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:
To do...
Display the current alarm
information of the pluggable
transceiver(s)
Display the currently measured
value of the digital diagnosis
parameters of the anti-spoofing
optical transceiver(s)
customized by H3C
