Hello, everyone!
This post will tell you one issue for Unable to add a N1SL-64 and N4SL64 card in slot17,12 in OSN 3500.
Problem description:
We have checked the issue, and unable to add N1SL64 & N4SL64 card in slot 17 & 12 in OSN 3500. We are getting Invalid Slot Id. Error Code 38663.
Handling procedure:
1. Check the NE version as per equipment type
2. Trying to add logically.
3. But unable to add, as per error snapshot, it is showing "Invalid Slot ID".
Root cause:
We have checked and found that SL64 must be installed in a valid slot in the subrack. Otherwise, the SL64 fails to work normally.
The slots valid for a board are determined by the following factors:
1. Slot bandwidth
2. Cross-connect capacity
3. Board version
The slots valid for the SL64 vary with the cross-connect capacity of the subrack. The slots valid for the SL64 are as follows:
a. When the cross-connect capacity is 40 Gbit/s, the SL64 can be installed in slots 8 and 11.
b. When the cross-connect capacity is 80 Gbit/s, the SL64 can be installed in slots 7, 8, 11, and 12.
c. When the cross-connect capacity is 120 Gbit/s, the N1SL64 can be installed in slots 7, 8, 11, and 12, the N4SL64 can be installed in slots 4-8 and 11-15. The N2SL64 cannot be installed in any slot of the subrack.
d. When the cross-connect capacity is 200 Gbit/s, the N1SL64/N2SL64 can be installed in slots 7, 8, 11, and 12. The N4SL64 can be installed in slots 5-8 and 11-14.
In this issue, cross-connect card inserted in the node is GXCSA and the higher order cross-connect capacity: 40Gbit/s.
And SL64 must be installed in a valid slot in the sub rack and vary with the cross-connect capacity. If the cross-connect capacity is 40Gbit/s, the SL64 can be installed in slots 8 and 11.
Solution:
Need to Change the cross-connect board to EXCSA or UXCSA (higher capacity).
That's all, I welcome everyone to leave a message and exchange in the comment area!
Thank you！
