Hello, friend!
If the OptiX OSN 500 does not detect the EM6T board, the possible causes are as follows:
1. The device version does not match the board version.
The functional version of the EM6T/EM6F is TNM1.
You can use the Navigator to query the versions of the equipment and boards.
2. The board is not in the specified slot.
The M6T/EM6F board can be installed in slots 3 and 4. The slot configuration priority is as follows: slot 4 > slot 3. The logical slots displayed on the NMS are the same as the physical slots.
3. board fault
If any board is faulty, contact Huawei technical support engineers.
