4.Replace the CD/diskette drive tray (see "Replacing the CD/Diskette Drive Tray").
SCSI Configuration Information
Although SCSI devices are installed in essentially the same way as other devices, their configuration requirements are different. To install and configure an external SCSI device, follow the guidelines in the following subsections.
SCSI Interface Cables
SCSI interface connectors are keyed for correct insertion. Keying ensures that the
SCSI ID Numbers
Each device attached to a SCSI host adapter must have a unique SCSI ID number from 0 to 15.
A SCSI tape drive is configured by default as SCSI ID 6.
NOTE: There is no requirement that SCSI ID numbers be assigned sequentially or that devices be attached to the cable in order by ID number.
Device Termination
SCSI logic requires that termination be enabled for the two devices at opposite ends of the SCSI chain and disabled for all devices in between. For internal SCSI devices, termination is configured automatically. For external SCSI devices, you should disable termination on all devices and use terminated cables. See the documentation provided with any optional SCSI device you purchase for information on disabling termination.
External SCSI Tape Drive
This subsection describes how to configure and install an external SCSI tape drive.
Installing an External SCSI Tape Drive
CAUTION: See "Protecting Against Electrostatic Discharge" in the safety instructions in your System Information document.
1.Turn off the system, including any attached peripherals, and disconnect the system from the electrical outlet.
2.Prepare the tape drive for installation.
Ground yourself by touching an unpainted metal surface on the back of the system, unpack the drive (and controller card, if applicable), and compare the jumper and switch settings with those in the drive documentation. Change any settings necessary for your system's configuration.
3.Connect the tape drive's interface cable to the external SCSI connector on the controller card.
4.Reconnect the system to its electrical outlet and turn the system on, including any attached peripherals.
5.Perform a tape backup and verification test with the drive as instructed in the software documentation that came with the drive.
Hard Drives
This subsection describes how to install and configure SCSI hard drives in the system's internal
Before You Begin
Before attempting to remove or install a drive while the system is running, see the documentation for the RAID controller card ensure that the system is configured correctly to support
SCSI hard drives are supplied in special drive carriers that fit in the
NOTE: You should only use drives that have been tested and approved by the system manufacturer for use with the SCSI backplane board.
You may need to use different programs than those provided with the operating system to partition and format hard drives. See "Installing and Configuring SCSI Drivers" in the User's Guide for information and instructions.
NOTICE: Do not turn off or reboot your system while the drive is being formatted. Doing so can cause a drive failure.
When you format a
