Dell PERC 4/DC - Manual (Page 59)

Step 8 Start the System
Replace the system cover and reconnect the AC power cords. Turn power on to the host system. Set up the power supplies so that the SCSI devices are
powered up at the same time as or before the host system. If the system is powered up before a SCSI device, the device might not be recognized.
During bootup, the BIOS message appears:
