Installing a RAID Controller Card
Your system supports the following drives:
l Up to two externally accessible 5.25-inch drives (typically optical and tape backup drives). An optical drive is standard in the first external drive bay, and
a tape backup device can be installed in the second external drive bay.
l An externally accessible 3.5-inch diskette drive.
l Up to four 1-inch SATA or SCSI hard drives. Four hard drive configurations are available:
¡ Cabled SATA drives. See "Cabled SATA and SCSI Hard Drives."
¡ Cabled SCSI drives (requires optional SCSI controller card). See "Cabled SATA and SCSI Hard Drives."
¡ Front-access (non-hot-plug) SCSI drives (requires optional SCSI backplane and optional SCSI controller card). See "Front-Access SCSI Hard Drives
(Non-Hot-Plug)" and "Installing the Optional SCSI Backplane Board."
¡ Hot-plug SCSI drives (requires optional SCSI backplane and optional SCSI RAID controller). See "Hot-Plug SCSI Hard Drives," "Installing a RAID
Controller Card," and "Installing the Optional SCSI Backplane Board."-+
Connecting Drives

Interface Cables
Most interface connectors are keyed for correct insertion. Keying ensures that the pin-1 wire in the cable connects to pin 1 in the connectors on both ends.
When you disconnect an interface cable, take care to grasp the cable connector, rather than the cable itself, to avoid stress on the cable.

Drive Cable Configurations
Your system can accommodate many different drive configurations, each with specific cable requirements. Table7-1 shows the cable requirements for common
drive configurations.
Table 7-1.DriveCableConfiguration

DC Power Cables
Each drive must connect to a DC power cable from the system power supply. These power cables are used for the 3.5-inch diskette drive, 5.25-inch devices,
and hard drives.
NOTE: Installing SATA and SCSI hard drives in the same system is not supported.
