Whether it is feasible to reset the system control boards in a new slave subrack only when this slave subrack is added

1. To add a slave subrack, set the DIP switches, power on the subrack, connect the ETH port, and check whether the indicator status is normal. No reset is required.
2. If the ID of the new subrack conflicts with the ID of an existing subrack, two methods are available. One method is to change the ID of the new subrack first, and then power off the entire NE to restart it. This process adversely affects services on the existing master and slave subrack. The other method is to change the ID of the new subrack, perform a warm reset on all boards in the existing master and slave subracks, and power off the new subrack to restart it.
