Dell PowerEdge 700 Installation And Troubleshooting Manual page 78

NOTE: The integrated drive controller on the system board can support only two SATA hard drives. If you are installing three or four SATA hard
drives, you must connect the drives to a SATA RAID controller card in a RAID or non-RAID configuration.
If you are installing up to four SATA hard drives:
a. Install a SATA RAID controller card in a 64-bit/66-MHz expansion slot. See
b. Connect the SATA cable assembly to port 0 through port 3 on the SATA RAID controller card and to drive 0 through drive 3, respectively. See
Figure 7-8.
Figure 7-8. Connecting Four Drives to a SATA RAID Controller Card
If you are installing a cabled SCSI drive, connect the SCSI interface cable to the hard drives and to the SCSI controller card. See Figure 7-9.
