Managing the cooling system 5 For example, if you are changing the temperature thresholds for a management module high and medium-high fan speeds, the system will accept the following values because the low temperature threshold for the high speed (79 C) is lower than the high temperature threshold (82 C) for the medium-high speed. Fan speed High Medium-high Low temperature threshold 79C 69C High temperature threshold 87C 82 C The device will not accept the following values because the low temperature threshold for the high speed (83 C) is higher than the high temperature threshold (82 C) for the medium-high speed. Fan speed High Medium-high Low temperature threshold 83C 69C High temperature threshold 87 C 82 C Displaying temperature thresholds for modules and fan speeds To check the current settings of the low and high temperature thresholds for modules and fan speeds, you can enter the show fan-threshold command at any level of the CLI.
