- `IDRAC_PASSWORD` parameter is only necessary if you're adressing a distant iDRAC. Default value is "calvin".
|
||||
- `FAN_SPEED` parameter can be set as a decimal (from 0 to 100%) or hexadecimal value (from 0x00 to 0x64) you want to set the fans to. Default value is 5(%).
|
||||
- `CPU_TEMPERATURE_TRESHOLD` parameter is the T°junction (junction temperature) threshold beyond which the Dell fan mode defined in your BIOS will become active again (to protect the server hardware against overheat). Default value is 50(°C).
|
||||
- `CHECK_INTERVAL` parameter is the time (in seconds) between each temperature check. Default value is 60(s).
