PowerChoice Manufacture Default Power Condition Timer Values
Default power condition timer values have been established to assure product reliability and data integrity. A minimum timer
value threshold of two minutes ensures the appropriate amount of background drive maintenance activities occur.
Attempting to set a timer values less than the specified minimum timer value threshold will result in an aborted EPC "Set
Power Condition Timer" subcommand.
