The computing nodes and fan modules of Huawei blade servers (such as E9000) must be configured in strict accordance with fixed principles to avoid overheating alarms and forced power-off of computing nodes due to insufficient cooling capacity of the chassis. Which of the following principles are wrong?
A. When half-width computing nodes or full-width computing nodes are fully configured, fan modules need to be fully configuredcorrect
B. When the number of half-width computing nodes <= 8 or the number of full-width computing nodes <= 4, the following slots must be equipped with fan modules: 1, 2, 3, 4, 7, 8, 9, 10, 13, 14
C. The half-width computing nodes must be closely configured according to the chassis slots from bottom to top, and the configuration sequence is: 1, 9, 2, 10, 3, 11, 4, 12, 5, 13, 6, 14, 7, 15, 8, 16
D. Full-width computing nodes must be closely configured according to the chassis slots from bottom to top, and the configuration sequence is: 1, 2, 3, 4, 5, 6, 7,
