This section describes the equipment type that support the intelligent power adjustment (IPA) function.
Table 1 shows the matching relationships among the versions of the board and equipment that support the IPA function.

Equipment Type |
|---|---|
| Detection Board: Optical Amplifier Board | OptiX OSN 3800A OptiX OSN 6800A OptiX OSN 8800(NA) series |
| Control Implementation Board: Optical Amplifier Board | |
| Detect Auxiliary Board: OTU, OSC, Line Board, TOM |
The power of the pump light from Raman amplifiers is very high. Hence, in a system configured with Raman amplifiers, it is suggested that you configure and enable IPA function before you turn on a Raman amplifier. After a fiber cut is detected, shut down the Raman amplifier. Then, there is no strong pump light sent from the LINE interface on the amplifier and thus the optical power of the entire line is on a safety level.
Table 2 shows the matching relationships among the versions of the board and equipment that support the IPA function of Raman systems.

Before the system is configured with IPA function, the lasers of Raman amplifiers can be enabled or disabled manually. When the system is configured with IPA function, the system determines whether to enable or disable the lasers of Raman amplifiers according to the fiber link status. Users can only disable the lasers manually. It is suggested that no manual operation is performed on lasers.
For a link with Raman amplifiers, it is not suggested that you disable or delete IPA function. During the commissioning, maintenance and replacement of a Raman amplifier, when you need to remove the fiber from the LINE interface on the amplifier, you can delete IPA function and then perform operations on the Raman amplifier. Before removing the fiber, make sure that the Raman amplifier is shut down.
Only NMS users that are assigned to the Device Operation Set have the authority to manage Raman amplifiers and IPA function.
If the Raman board is rebooted while the IPA function is working (enabled), and this configuration was previously saved on the SCC, then IPA function is recovered to its original status (enabled) once the reboot process finishes.
