Value Name Description Reference
0 mechoff An off state where no Energy Object features are available. The Energy Object is unavailable. No energy is being consumed, and the power connector can be removed. [RFC7326]
1 softoff Similar to mechoff(0), but some components remain powered or receive trace power so that the Energy Object can be awakened from its off state. In softoff(1), no context is saved, and the device typically requires a complete boot when awakened. [RFC7326]
2 hibernate No Energy Object features are available. The Energy Object may be awakened without requiring a complete boot, but the time for availability is longer than sleep(3). An example for state hibernate(2) is a save-to-disk state where DRAM context is not maintained. Typically, energy consumption is zero or close to zero. [RFC7326]
3 sleep No Energy Object features are available, except for out-of-band management, such as wake-up mechanisms. The time for availability is longer than standby(4). An example for state sleep(3) is a save-to-RAM state, where DRAM context is maintained. Typically, energy consumption is close to zero. [RFC7326]
4 standby No Energy Object features are available, except for out-of-band management, such as wake-up mechanisms. This mode is analogous to cold-standby. The time for availability is longer than ready(5). For example, processor context may not be maintained. Typically, energy consumption is close to zero. [RFC7326]
5 ready No Energy Object features are available, except for out-of-band management, such as wake-up mechanisms. This mode is analogous to hot-standby. The Energy Object can be quickly transitioned into an operational state. For example, processors are not executing, but processor context is maintained. [RFC7326]
6 lowMinus Indicates that some Energy Object features may not be available and the Energy Object has taken measures or selected options to use less energy than low(7). [RFC7326]
7 low Indicates that some Energy Object features may not be available and the Energy Object has taken measures or selected options to use less energy than mediumMinus(8). [RFC7326]
8 mediumMinus Indicates that all Energy Object features are available but the Energy Object has taken measures or selected options to use less energy than medium(9). [RFC7326]
9 medium Indicates that all Energy Object features are available but the Energy Object has taken measures or selected options to use less energy than highMinus(10). [RFC7326]
10 highMinus Indicates that all Energy Object features are available and the Energy Object has taken measures or selected options to use less energy than high(11). [RFC7326]
11 high Indicates that all Energy Object features are available and the Energy Object may use the maximum energy as indicated by the Nameplate Power. [RFC7326]
