Whether SCC replacement in a slave subrack affects services
If SCC 1+1 protection has been configured, SCC replacement in a slave subrack has no impact on the system. If SCC 1+1 protection has not been configured, the following impact may be present before the newly configured SCC restarts from the reset triggered during board replacement: 1. The fan speed mode is changed from Auto speed mode to High Speed mode. 2. The ESC or OSC communication of the slave subrack fails. 3. The POWER_FAIL alarm in the slave subrack cannot be reported. 4. Subrack ID conflicts with the ID of the slave subrack cannot be detected. 5. In the slave subrack, some optical-layer boards go offline and cannot be managed, but services are not affected.

Method used to determine whether the new SCC board is initialized when one SCC board in an OSN 6800 subrack equipped with two SCC boards is replaced
The new SCC board will complete the initialization 15 minutes later after being inserted into the slot housing the original SCC board.

Whether a system control board is required in an OSN 8800 platform subrack when it is used as a slave subrack
When an OSN 8800 platform subrack functions as a slave subrack, it does not require a system control board. Its IU17 and IU18 slots can be used to house service boards. When it functions as a master subrack, a system control board is required.

Whether system control boards are required when NG WDM devices are used as slave subracks
1. OSN 8800 subracks are classified into T16, T32, T64, platform subracks, and universal platform subracks (UPSs). Principles for configuring system control boards on OptiX OSN 8800 T16 subracks: For electrical subracks, TN16XCH or TN16UXCM boards must be configured. For optical subracks (master subrack), the TN16SCC board must be configured. For optical subracks (slave subracks), no system control boards need to be configured. Principles for configuring system control boards on OptiX OSN 8800 platform subracks and UPSs: For the master subrack, system control boards must be configured. For slave subracks, no system control boards need to be configured. Principles for configuring system control boards on other OptiX OSN 8800 subracks: System control boards must be configured on both the master and slave subracks. 2. OptiX OSN 9800 subracks are classified into U16, U32, U64, P18, and UPSs. CTU system control boards must be configured on the U16, U32, and U64 subracks of OptiX OSN 9800. 52SCC boards must be configured for OptiX OSN 9800 P18 subracks and UPSs. Principles for configuring system control boards: For the master subrack, system control boards must be configured. For slave subracks, no system control boards need to be configured. 3. System control boards must be configured on both the master and slave subracks of OptiX OSN 6800.

Precautions for replacing the SCC board in the master subrack of OSN 8800
