Diagnosing transceiver modules
The device provides the alarm and digital diagnosis functions for transceiver modules. When a
transceiver module fails or is not operating correctly, you can perform the following tasks:
• Check the alarms that exist on the transceiver module to identify the fault source.
• 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 commands in any view:
Task Command Remarks
Display transceiver alarms.
display transceiver alarm
{ interface [ interface-type
interface-number ] }
N/A
Display the current values of the
digital diagnosis parameters on
transceiver modules.
display transceiver diagnosis
{ interface [ interface-type
interface-number ] }
This command cannot display
information about some
transceiver modules.

If you install a transceiver module that has no vendor name or has a vendor name other than HP, the
system repeatedly outputs traps and logs to notify you to replace the module. To continue to use a
transceiver module that is manufactured or customized by HP but has no vendor information, you can
disable alarm traps so the system stops outputting alarm traps.
To disable alarm traps for transceiver modules:
Step Command Remarks
1. Enter system view.
system-view N/A
2. Disable alarm traps for
transceiver modules.
transceiver phony-alarm-disable
By default, alarm traps are
enabled for transceiver modules.
