How to test 1+1 Protection of the Cross-Connect Board and Clock Board for OptiX OSN 8800?

1+1 protection is configured by using the cross-connect board and clock board. This section describes how to test the 1+1 protection switching of the cross-connect board and clock board, thus ensuring that the protection switching is normal.

Prerequisites

For the OptiX OSN 8800 T16, slots 9 and 10 must house the high cross-connection, system control and clock processing board.

For the OptiX OSN 8800 T32, slots 9 and 10 must house the cross-connect board.

For the OptiX OSN 8800 T64, slots 9 and 43 (or slots 10 and 44) must house the cross-connect board.

For the OptiX OSN 8800 T32, slots 42 and 44 must house the clock board.

Procedure

1. Double click the ONE icon on the Physical Map, and the NE Panel tab is displayed.
2. Right-click the NE icon and choose NE Explorer.
3. Choose Configuration > Board 1+1 Configuration. Click Query. The queried Active Board should be the same as the Working Board.
   
   

   For the OptiX OSN 8800 T16, Working Board is the cross-connection, system control and clock processing board in slot 9, and Protection Board is the cross-connection, system control and clock processing board in slot 10. Active Board is the cross-connection, system control and clock processing board that is actually working.

   For the OptiX OSN 8800 T32, Working Board is the cross-connect board in slot 9, and Protection Board is the cross-connect board in slot 10.Active Board is the cross-connect board that is actually working.

   For the OptiX OSN 8800 T64, Working Board is the cross-connect board in slot 9 or 10, and Protection Board is the cross-connect board in slot 43 or 44. Active Board is the cross-connect board that is actually working.

   For the OptiX OSN 8800 T32, Working Board is the clock board in slot 42, and Protection Board is the clock board in slot 44. Active Board is the clock board that is actually working.

   For OptiX OSN 8800 T64, Working Board is the clock board in slot 75, and Protection Board is the clock board in slot 86. Active Board is the clock board that is actually working.

4. Select Cross-Connect Board 1+1 Protection or Clock 1+1 Protection, and then click Working/Protection Switching. In the Microsoft Internet Explorer dialog box that is displayed, click OK. In the Operation Result dialog box that is displayed, click Close.

   When you select the cross-connect board or the clock board for switching, the cross-connect board and the clock board perform switching at the same time.

5. Repeat step 3 to perform the query. The queried Active Board should be the same as the Protection Board.
6. Select Cross-Connect Board 1+1 Protection or Clock 1+1 Protection, and then click Restore Working/Protection. In the Confirm dialog box that is displayed, click OK. In the Operation Result dialog box that is displayed, click Close.

   When you select the cross-connect board or the clock board for switching, the cross-connect board and the clock board perform switching at the same time.

   The 1+1 protection switching on the cross-connect boards and clock boards is non-revertive. When Protection Board becomes Active Board, restore the cross-connect boards and clock boards to the original working/protection state by removing the protection board, or by clicking Restore Working/Protection on the NMS.

7. Repeat step 3 to perform the query. The queried Active Board should be the same as Working Board.
