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.
Power Condition Name | Manufacturer Default Timer Values |
|
|
Idle_a | 2 min |
|
|
Idle_b | 4 min |
|
|
Idle_c | 10 min |
|
|
Standby_z | 15 min |

Setting power condition timer values less than the manufacturer specified defaults or issuing the EPC "Go to Power Condition" subcommand at a rate exceeding the default timers may limit this products reliability and data integrity.
