1 Introduction
The Certance DAT24 is a digital audio tape (DAT) drive that supports the Digital Data Storage (DDS-
3) tape format. The DAT24 drive provides a typical capacity of 24 Gbytes, assuming 2:1 data com
pression (native capacity is 12 Gbytes).
The DAT24 tape drive can connect to a standard, single-ended SCSI or SCSI-2 interface. You can
use a 50-conductor flat cable or a 25-signal twisted-pair cable to connect the drive to a SCSI host
adapter. The cable should not exceed 6 meters (19.5 feet).
The DAT24 drive is offered as internal and desktop versions:
• The internal version is available as a 3.5-inch or 5.25-inch tape drive. It provides a 50-pin,
dual-row single-ended SCSI connector at the back of the drive.
• The desktop version provides two 50-pin, shielded connectors (ANSI Alternative 2) on the
back panel. These connectors consist of two rows of ribbon contacts spaced 2.16 mm
(0.085

Introduction
This chapter explains how to install the internal and desktop DAT24 tape drives.
Topics covered in this chapter are:
• “Unpacking and Inspection” on page 10
• “Installing an Internal DAT24 Drive” on page 10
• “Installing the Desktop DAT24 Drive” on page 18
Unpacking and Inspection
Although drives are inspected and carefully packaged at the factory, damage may occur during
shipping. Follow these steps for unpacking the drive.
1. Visually inspect the shipping containers and notify your carrier immediately of any damage.
2. Place shipping containers on a flat, clean, stable surface; then carefully remove the contents. If
the equipment is damaged, notify your Certance representative.
3. Always save the containers and packing materials for any future reshipment.
Installing an Internal DAT24 Drive
Installing the internal DAT24 drive involves the following steps:
1. Observe the guidelines and cautions for handling internal tape drives. See “Internal Tape
Drive Guidelines and Cautions” on page 11.
2. Configure the drive. See “Configuring the Internal DAT24 Drive” on page 11.
3. Mount the drive. See “Mounting an Internal DAT24 Drive” on page 15.
4. Connect the power and interface cables. See “Connecting Power and Interface Cables” on
page 17.
5. Registering the tape drive. After you install the DAT24, register it. Registering it ensures that
you will receive the latest information about the drive, as well as other product, service, and
support information. For your convenience, you can register the DAT24 through our Web site
at http://register.certance.com.
NOTE: Internal drives come in two mounting configurations. Drives configured for 5.25-inch
bays are identical to those designed for 3.5-inch bays, except that drive-mounting brackets have
been added on each side of the drive. Installation procedures are the same for both drive
configurations.

Installation Installing an Internal DAT24 Drive
Internal Tape Drive Guidelines and Cautions
The following guidelines and cautions apply to handling and installing the internal DAT24 tape
drive. Keep them in mind as you install the internal drive.
• Handle the drive by the sides rather than by the top cover to reduce the risk of dropping the
drive or damaging it during installation.
• Internal drives contain some exposed components that are sensitive to static electricity. To
reduce the possibility of damage from static discharge, the drives are shipped in a protective
antistatic bag. Do not remove the drive from the antistatic bag until you are ready to install it.
• Before you remove the drive from the antistatic bag, touch a metal or grounded surface to dis-
charge any static electricity buildup from your body.
• Always lay the drive either on top of the antistatic bag or place it inside of the bag to reduce
the chance of damage from static discharge.
Configuring the Internal DAT24 Drive
Before you install the internal DAT24 tape drive in your computer, you may need to set the drive's
SCSI ID or other drive features. Most features are set using a bank of dip-switches on the underside
of the drive (see
figure the drive for remote SCSI address selection, use the jumpers on the back of the drive, above
the interface and power connectors.
Figure 1 on page 11). To control SCSI termination and terminator power, or to con-
Dip switches

Figure 1. DIP Switches and Jumpers for Internal DAT24 Tape Drives
The default settings for internal DAT24 tape drives are:
• SCSI ID is 0.
• Drive reads and writes both MRS and non-MRS 4-mm media.
• Parity checking is disabled.
• Data compression is enabled.
• Power-on self-test diagnostics are disabled.
• SCSI termination is disabled.
If the default settings are appropriate for your computer system, skip ahead to “Mounting an Internal
DAT24 Drive” on page 15. Otherwise, proceed to “Changing DIP Switch Settings” on page 12.
