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 Installation
CAUTION:
Only trained service technicians are authorized to remove the system cover and access any of

Hard Drives
This subsection describes how to install and configure SCSI hard drives in the system's internal hard-drive bays.
CAUTION:
Only trained service technicians are authorized to remove the system cover and access any of
the components inside the system. See your System Information Guide for complete information about
safety precautions, working inside the computer, and protecting against electrostatic discharge.
Before You Begin
Hard drives are supplied in special drive carriers that fit in the hard-drive bays.
NOTICE:
Before attempting to remove or install a drive while the system is running, see the documentation for the
host adapter to ensure that the host adapter is configured correctly to support hot-pluggable drive removal and
insertion.
NOTICE:
Do not turn off or reboot your system while the drive is being formatted. Doing so can cause a drive failure.
NOTE:
Only use drives that have been tested and approved for use with the SCSI backplane board.
