Setting the Raman board alarm reporting parameter to Enabled
The CRPC01 board supports fiber cut detection. That is, when the CRPC01 board detects an IPA trigger condition, the IPA function will shut down the transmitting laser on the CRPC01 board. This, however, can be achieved only when the following conditions are satisfied: 1. The CRPC01 board is configured as the Raman Amplifier. 2. At least one of the 192.4 THz to 192.1 THz wavelengths is configured in the system. In a system with 50 GHz channel spacing, at least one of the following wavelengths is configured in the system: 192.4 THz, 192.35 THz, 192.3 THz, 192.25 THz, 192.2 THz, 192.15 THz, and 192.1 THz. In a system with 100 GHz channel spacing, at least one of the following wavelengths is configured in the system: 192.4 THz, 192.3 THz, 192.2 THz, and 192.1 THz. 3. Raman Board Alarm Reporting is set to Enabled. 4. Raman Board Threshold (dBm) is set correctly. Note: If wavelengths 192.4THz-192.1THz are not configured in the system, Raman Board Alarm Reporting must be set to Disabled.

Method used to set Shelf Link Mode
Before connecting a subrack, you need to set Shelf Link Mode to be consistent with the actual physical cascading mode the subracks on the U2000 to ensure proper functioning of the subracks and normal communication between subracks on an NE. The procedure is as follows: In the NE Explorer, select the NE and choose Configuration > Shelf Link Management. In the right pane, click the Shelf Link Mode. Double-click the desired NE, and set it to Tree or Ring according to the actual physical cascading mode of the subracks. Click Apply.
