Installing Your Internal Drive
Before You Start
Check System Prerequisites
Before you start installing, make sure that your computer has the
following:
A properly installed and configured SCSI host adapter (SCSI-2 or SCSI-3
compliant)
For optimal performance, Hewlett-Packard recommends that your DLT
drive is placed on a dedicated SCSI bus. If this means you need to install a
new host adapter, contact your supplier. Many host adapters are available,
and your supplier will tell you which are suitable for HP SureStore DLT
drives.
HP SureStore DLT 40i only: An internal SCSI ribbon cable with a spare
50-pin connector
If your computer uses wide SCSI, you need to use the adapter supplied with
the drive that enables you to connect a narrow SCSI device (50 pins) into
the wide SCSI bus (68 pins).
HP SureStore DLT 70i and 80i only: An internal SCSI ribbon cable with a
spare 68-pin connector. The drive requires a wide HBA to perform to
specification, or, in the case of the HP SureStore DLT 80i, an LVD (low-
voltage differential) HBA.
Two adjacent, 5¼-inch, half-height bays in which to install the drive
Note that the depth of the drive — 228.3 mm (9 in) behind the front bezel —
is greater than the depth of most 5¼-inch devices. Make sure that the bays
can accommodate this depth.
Mounting hardware
To install the drive, you may need to fix it to a set of rails or a tray:
• A tray for use with HP NetServer L-series is provided with the drive.
• A pair of rails for use with Compaq servers is provided with the drive.
• For other computers, trays or rails are likely to be supplied with the
system. For Dell rails, see Appendix A for order numbers.
Note Some computer companies use non-standard rails and do not include
spares with the computer. If this is the case with your system, you will
have to order rails from the computer manufacturer before you can install
the tape drive.
If you are not sure what type of rails to use, refer to your computer
documentation. You may want to have this documentation available for
reference during the installation process.
