How many functioning fans are required to cool the T3?
A. 3 out of the 4 fans must be operating to keep the T3 up and running. Q. So if I lose a power supply in a PCU, aren’t I going to lose 2 out of the 4 fans? You just said I need 3! A. The fans are powered through the T3’s midplane, so even if one power supply fails, it’s fans will draw power from the other PCU.
