8.2.3Replacing the system fan
VCAUTION!
Since the standard system fans 1 and 2 are not redundant, these system fans have to be replaced immediately.
If one of the four redundant system fans (1&3 and 2&4) fails, one of the two predetermined fans (system fan 3 and 4) increases its power to ensure that the server is cooled properly. The redundant system fans should be replaced as soon as possible.
