c) Copy the globally unique identifier (GUID) for the “Allow Throttle States” processor power
policy.
d) Set the “Allow Throttle States” policy value to 1 by using the following command:
powercfg -setacvalueindex scheme_current sub_processor 3b04d4fd-1cc7-4f23-
ab1c-d1337819c4bb 1
3. Power Supply Issue
NM Policies work only if PMBus compatible power supplies are connected. Check Table 2 for details.
With a single PSU in location PS1, NM works properly.
NM will report wattage and set policies to limit wattage correctly.
With a single PSU in location PS2, NM will report wattage as 0 and NOT set policies.
4. Why does NM not limit the power in when the chassis of the server is open?
There are two reasons why NM won’t limit the power consumption in an open chassis condition:
a) You have a cooling efficiency problem in the closed box and CPU was throttled
b) You have a cooling efficiency problem in the open box and fans start running faster (and consume
more power). As NM could not limit the power, the power consumption of the CPU went up. You will
observe that the fans are running faster.
