fuelg command
This command displays power domain information, listing the power supplies that are installed in the Lenovo Flex System chassis and information about power usage. This command also configures policies for power redundancy loss and limiting fan noise during thermal events.
If command syntax is not correctly entered, or if a command fails to run, an error message is returned. See Common errors for a list of error messages that apply to all commands or fuelg command errors for a list of error messages that are specific to the fuelg command.
Function | What it does | Command | Target (see paths in Command targets) |
---|---|---|---|
Display power domain status overview | Displays health status, total power usage, total dc power available, total ac power in use, thermal response (acoustic mode) settings, total thermal output in BTU/hour, chassis static power limit, and the hot air recirculation detection state. Note The chassis static power limit (-spl) indicates the set value as both a percentage and a wattage, along with the upper and lower wattage values that can be set. | fuelg | Lenovo Flex System chassis:

Set hot air recirculation detection state | Enables or disables hot air recirculation detection for the Lenovo Flex System chassis. | fuelg -har setting where a setting of:
This command can only be run by users who have one or more of the following command authorities:
| Lenovo Flex System chassis:
|
Set hot air recirculation threshold | Sets the hot air recirculation threshold, the maximum allowable temperature difference between the input and output sensors, for the specified command target. If this threshold is exceeded, a hot air recirculation event is created in the CMM event log. | fuelg -hart setting where setting is a temperature, between, 5.00 and 9.00 Celsius, that triggers a hot air recirculation event. For example, a value of 6.00 would trigger an event if the output temperature was more than 6.00 degrees greater than the input temperature. This command can only be run by users who have one or more of the following command authorities:
| Lenovo Flex System chassis:
|
Display air flow trending for specified time period | Displays chassis air flow trending information, in cubic feet per minute (CFM), for the selected time interval. | fuelg -aft period where period is 1, 6, 12, or 24 hours. | Lenovo Flex System chassis:
|
Thermal event response (acoustic mode) | Sets the acoustic mode of Lenovo Flex System chassis fan system response to thermal events. Note When the CMM is installed in a Lenovo Flex System Carrier-Grade chassis:
| fuelg -am setting where the acoustic-mode setting is off or a number from 1 to 5, inclusive. A value of off disables acoustic mode (fans run at maximum requested speed, providing highest cooling). A value of 1 provides low attenuation (higher cooling). A value of 5 provides highest attenuation (lowest cooling). If you enter a value outside this range, an error will be displayed. This command can only be run by users who have one or more of the following command authorities:
