Dear rat139!

For the first question, there are two ways: 

The first way： We can do the protection switching of the equipment by fiber removing.

1. Remove the fiber on the IN optical port of the working line board N1 at the station to perform the switching.

2. Check the channel status for ODUk SNCP protection of station

--》Choose Configuration > WDM Service Management from the Function Tree. Click SNCP Service Control, and click Query.

--》In the fiber removing mode, Channel Status of the working cross-connection is SF, and Channel Status of the protection cross-connection is Normal. The status of the protection group is SF Switching.

3. In the NE panel of the station, right-click the board and choose Browse Current Alarms. The ODU_SNCP_PS alarm must be reported.

4. Test the services by using a signal analyzer. The services should be available, no bit error is generated.

5. To restore the test environment for the switching modes in step 1, reconnect the fiber.

6. After the WTR Time(mm:ss) elapses, click Query. The status of the protection group should be Normal State.

The second way：We can do the protection switching of the equipment by forced switching.

1. In the NE panel of the station, choose Configuration > WDM Service Management from the Function Tree. Click SNCP Service Control.

2. Click Query.

3. In the SNCP Service Control window, select the working cross-connection and click Function. In the displayed menu, select Force to Protection to perform the switching. Click OK in the displayed dialog box.

4. Check the channel status for ODUk SNCP protection of station

In the SNCP Service Control window, click Query.

In the forced switching mode, Channel Status of the working cross-connection is Normal, and Channel Status of the protection cross-connection is also Normal. Status of the protection group is Forced (from working to protection) switching state.

5. In the NE panel of the station, right-click the board and choose Browse Current Alarms. The ODU_SNCP_PS alarm must be reported.

6. Test the services by using a signal analyzer. The services should be available, no bit error is generated.

7. To restore the test environment for the two switching modes in step 1, use the following methods:

Select the working cross-connection, and click Function. In the displayed menu, choose Clear. Click OK in the displayed dialog box.

8. After the WTR Time(mm: ss) elapses, click Query. The status of the protection group should be Normal State.

For the second question：

1.Log into the NMS. Double-click the NE in the Main Topology. The Running Status of the NE is displayed.

2.Right-click a NE, and choose NE Explorer to display the NE Explorer window.

3. Select the NE and choose Configuration > WDM Service Management from the Function Tree. Click SNCP Service Control tab.

4. Click Query. Then, all ODUk SNCP protection groups are listed.

See the following figure：
