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.
