The logical board of the SLQ16 cannot be created on the T2000. This fault is rectified after the logical board of the cross-connect board is changed.
Symptom
A customer fails to add the logical board of the SLQ16 on the OptiX OSN 3500, and the customer mentions that the cross-connect board is changed from the UXCSA to the SXCSA on site.
Cause Analysis
The SLQ16 is applicable only to the OptiX OSN 3500 of 200 Gbit/s cross-connect capacity. If the cross-connect capacity decreases to 40 or 80 Gbit/s, the SLQ16 fails to work normally. The SXCSA has the board version replacement function. If the original logical board is the UXCSA, the system considers that the cross-connect board is the UXCSA by default, rather than the SXCSA. As a result, the logical board of the SLQ16 cannot be added.
Procedure
- Query the physical and logical boards in slots 9 and 10 on the T2000. All the physical and logical boards are the UXCSA.
- This is because the customer does not change the logical cross-connect board after the replacement of the physical cross-connect board. Change the logical cross-connect board to the SXCSA. Then, the logical board of the SLQ16 is added successfully.
