Possible causes include:
1. The board hardware had a fault.
2. NE40E running V6R1 did not support the board (BOM number: 03030ETR)
Huawei performed the following operations to address the problem:
1. Checked the mapping table and confirmed that 4*OC-12c LPUG board was supported in V6R1.
2. Install the board on an NE80E and the problem did not occur, indicating the board hardware was normal. 3. Confirmed that NE40E-X3 did not support LPUG board.
NE40E-X3s do not support LPUG boards.
Replace the LPUG board with an LPUF board.
In V6R1, only NE40E-X3s do not support LPUG boards.
