SCSI Hard-Drive Cabling Guidelines
Your system features five standard internal hard-drive bays that accommodate up to five 3.5-inch SCSI hard drives. Systems with an optional RAID controller
card or optional ROMB support hot-plug SCSI drive operation.
The system's peripheral bay can accommodate a removable drive carrier that supports an optional diskette drive and optional optical drive.
Installing SCSI Hard Drives
Figure7-1 shows the SCSI ID numbers of the five standard drive bays.

Before You Begin
SCSI hard drives are supplied in special drive carriers that fit in the hard-drive bays.
You may need to use different programs than those provided with the operating system to partition and format SCSI hard drives.
When you format a high-capacity SCSI hard drive, allow enough time for the formatting to be completed. Long format times for these drives are normal. A 9-GB
hard drive, for example, can take up to 2.5 hours to format.

Installing a SCSI Hard Drive

1. If the system does not have an optional RAID controller card or optional integrated ROMB, shut down the system.

2. Remove the front bezel, if attached. See "Opening the System" in "Troubleshooting Your System."

3. Open the hard-drive handle. See Figure7-2.

NOTICE: Before attempting to remove or install a drive while the system is running, see the documentation for the optional RAID controller card or
optional ROMB to ensure that the host adapter is configured correctly to support hot-plug drive removal and insertion.
NOTE: It is recommended that you use only drives that have been tested and approved for use with the SCSI backplane board.
NOTICE: Do not turn off or reboot your system while the drive is being formatted. Doing so can cause a drive failure.
NOTICE: Hot-plug drive installation is not supported for systems without an optional RAID controller card or optional ROMB.
