Attention: Incorrect configured subrack type of OSN8800 T32

During a OSN8800 T32 commissioning, board TN54NS4 cannot be added and noticed does not support board type and error code 38664.

Nesoft version: 5.51.8.16 (V1R7C00SPC300)

U2000 version: V1R6C02SPC3001. Preliminary analysis the reason could be cause of Nesoft version is too low, does not support TN54NS4 board.

Check the version matching table and found that the version support TN54NS4 board.

2. Use Navigator command to check the Nesoft version support TN54NS4 or not.

Run command in Navigator:

:cfg-add-board:bid,54NS4:

According to the output of Navigator, the Nesoft is support TN54NS4.

Then it could be a configuration problem or software bug.

3. Because Huawei wdm board TN54NS4 is 100G board, maybe caused by not enough capacity of the slot, because different subrack type support different cross-connect capacity.

Use Navigator command to query subrack information:

:cfg-get-shelf

Output:

SHELF INFO

SHELF-ID SHELF-TYPE

0 shelf8800T32

Total records :1

According to the output, the subrack type is Standard version.

:cfg-get-physhelf

PHY-SHELF INFO

SHELF-ID SHELF-TYPE

0 shelf8800T32E

But the physical subrack type is Enhanced version.

The subrack type shall change to Enhanced type.

4. Because this is a new equipment, problem resolved by clear the Database, change subrack type to "Enhanced", add TN54HS4 again and successfully.

Incorrect subrack type cause the problem, OSN8800T32 standard version does not support TN54NS4, change the subrack to "Enhanced" version to support the board to resolve the problem.

Problem solved by change the subrack type to "Enhanced".

The specific parameter shall be clearly discribed in product documentation for the exact type of subrack.

The engineer shall carefully study the Huawei transmission network product documentation before any operation and follow the guidance.
