Diagnosing transceiver modules
The device provides the alarm function and digital diagnosis function for transceiver modules. When a
transceiver module fails or inappropriately work, you can check for 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.
Perform the following commands in any view to diagnose transceiver modules:

Displaying and maintaining device management
For diagnosis or troubleshooting, you can use separate
display
commands to collect running status data
module by module, or use the
display diagnostic-information
command to bulk collect running data for
multiple modules. The
display diagnostic-information
command equals this set of commands:
display
clock
,
display version
,
display device
, and
display current-configuration
.
