ApEnvMonState  
Represents the state of a device being monitored. Valid values are: initial (1): the environment is at initial state. normal (2) : the environment is good, such as low temperature. minor (3) : the environment is not good, such as: fan speed is more than minor alarm threshold, but less than major alarm threshold. major (4) : the environment is bad, such as: fan speed is more than major alarm threshold, but less than critical alarm threshold. critical(5): the environment is very bad, such as Fan speed is more than critical threshold. shutdown(6): the environment is the worst, the system should be shutdown immediately. notPresent(7): the environmental monitor is not present, such as temperature sensors do not exist. notFunctioning(8): the environmental monitor does not function properly, such as 1. I2C fail 2. a temperature sensor generates a abnormal data like 1000 C. unknown(9) : can not get the information due to internal error.
