Whether SCC replacement in a slave subrack affects services

17

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.

Whether replacing server NICs affects services
NIC replacement will cause the MAC address change, and services related to the MAC address will be affected.

Whether replacing server CPUs affects services
Power off the server before you replace CPUs. System information and files are stored on disks. After a CPU is replaced, and the system is powered on and restarted, the system automatically loads the CPU driver and identifies the CPU. Therefore, CPU replacement does not affect services nor data.

Whether replacing server DIMMs affects services
Power off the server before you replace DIMMs. When the device is powered off, data in DIMMs will be written into disks and will not get lost. Therefore, DIMM replacement does not affect services nor data.
