Solution:

This function is used to situation of that power supply is unable to provide sufficient start-up current for whole system including RAID controllers, hard disks, and environment monitor devices. The default setting is to start all hard disks when powered-on. Through this function, you change the start-up status to "Spin-up" serially in random sequence" or "Spin up at SCSI command". The redundant power supply of RAID500 can provide sufficient peak current when system powered on. So, it is suitable regardless of any "SCSI Motor Spin Up" mode.
