2.
Execute the display transceiver information interface command in probe view to verify that
the transceiver modules at the two ends are the same type, and the transceiver module is
compatible with the interface.
3.
Verify that the fiber type is compatible with the transceiver module.
4.
Execute the display hardware internal module interface-type interface-number reg 0
command to view the CPLD. Determine whether a transmit or receive failure or a hardware
failure has occurred.
5.
If the problem persists, contact H3C Support.
Transceiver module type not recognized
Symptom
The system generates a message that reports unknown transceiver module type.
Solution
To resolve the problem:
1.
Execute the display hardware internal module interface-type interface-number reg 0
command in probe view to verify that the transceiver module is not a counterfeit and has an
electronic label.
If the transceiver module is a counterfeit, the transceiver module type fails to be displayed
correctly and the display transceiver manuinfo interface and display transceiver
diagnosis interface commands are not available.
2.
Execute the display hardware internal transceiver register interface command in probe
view to verify that the system can read the values on the registers in the transceiver module.
3.
If the problem persists, contact H3C Support.
Interface or transceiver module alarm
Symptom
An interface alarm is generated, or messages that report transceiver module insertion and removal
are output repeatedly.
Solution
To resolve the problem:
1.
Verify that the CPLD version of the interface module is updated to the most recent version.
2.
Execute the display transceiver alarm interface command to determine whether an alarm
was generated and whether the alarm is consistent with the output messages.
3.
If the problem persists, contact H3C Support.
