FastIron X Series fans
The FastIron X Series cooling fans cool the CPU, main memory, and voltage regulators. The fans use either a push or pull configuration to
move the air from the left side of the device to the right side of the device.
The fans in the 24-port FastIron X Series switches operate at a single speed and do not support multiple fan speeds.
The fans in the 48-port FastIron X Series switches include two three-speed fans that operate at low speed, then adjust based on the
ambient temperature and configured or default temperature thresholds. Both fans operate simultaneously at the same speed. If one fan
fails, it does not affect the operation of the other fan.
The fans can operate at speeds of low, medium, and high. The system uses a
fan speed switch
and a default or configured temperature
threshold associated with it to determine at which speed the fan should operate. If desired, you can change the settings of the temperature
thresholds associated with fan speed switches. For more information, refer to
