Installing the Optional SCSI Backplane Board
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.

connected to the SCSI backplane (See
Figure 7 -12 .)
38-cm (15-inch) 68-pin SCSI 1-drop
cable (unterminated) SCSI backplane and the SCSI controller card
NOTICE: To avoid electrical damage to internal system components, install a cover connector on any unused connectors on hard-drive power cables.
