One fan can fail without affecting the thermal performance of the system.
Redundant fan controllers and other internal mechanisms are in place to ensure
that any single fan tray does not go down.
If any single fan fails, the system continues to operate under all conditions. Two
fan failures might cause alarms from ASIC when the temperature exceeds the
threshold. At 104°F (40°C) or less, a single fan tray can be removed and the system
can continue to operate long enough to allow for replacement of a failed fabric
module or fan tray.
