Chapter 3 Installing Mass Storage Devices CAUTION To prevent damage to the Hot Swap SCSI hard disk drives, don't use a HVD (high voltage differential) DAC controller. If the hardware mirroring option is required (which uses the SCSI channel of the HP NetRAID Controller board), refer to " Optional SCSI Drive Controller" later in this chapter. The instructions describe how to move the SCSI cable from the system board to the SCSI connector on the HP NetRAID Controller board. Refer to the documentation provided by the supported HP NetRAID Controller board for external cabling requirements.

CAUTION
To prevent damage to the Hot Swap SCSI hard disk drives,
don’t use a HVD (high voltage differential) DAC controller.
If the hardware mirroring option is required (which uses the SCSI channel of the
HP NetRAID Controller board), refer to " Optional SCSI Drive Controller" later
in this chapter.
The instructions describe how to move the SCSI cable from the
system board to the SCSI connector on the HP NetRAID Controller board.
Refer
to the documentation provided by the supported HP NetRAID Controller board
for external cabling requirements.
