1 Introduction
1.1 Overview
This chapter introduces your DLT VS160 Internal Drive, DLT
VS160 Tabletop Drive, and this Installation and Operations
Manual.
1.2 DLT VS160 Drive Overview
Your DLT VS160 Drive is a value-priced, high-reliability, high-
capacity linear streaming cartridge tape drive designed for use
on entry to midrange computing platforms. With a combination
of data compression and compaction, the DLT VS160 Drive
offers a formatted cartridge capacity of 80GB (160GB assuming
a 2:1 compression ratio) and a sustained user data transfer rate
of 8 MB/s (up to 16 MB/s with 2:1 compression). The capacity
you realize in practice depends on the data set, which affects
the actual compression ratio.
Your DLT VS160 Drive is built on a 5¼-inch, half-height form-
factor, using a ½-inch tape. Its design includes a four-channel
read/write head, Lempel-Ziv (DLZ) high-efficiency hardware
data compression, and tape-mark directory to achieve fast data
throughput and data access times.
1.2.1 Features
Your DLT VS160 Drive has the following features:
• Supported formats: ValuSmart 160 (read/write using
ValuSmart Media 1 cartridges), DLT1/VS80 (read only
using DLTtape™ IV cartridges)
• Uses ValuSmart Media 1 cartridges
• 5.25-inch half-height form-factor
• Formatted cartridge capacity of 80GB native, 160GB
compressed
• Sustained user data transfer rate of 8 MB/s native, up to 16
MB/s with compression*
• Requires a wide-ultra, Ultra2, Ultra160, or Ultra3, Low-
Voltage Differential (LVD) or Single-Ended (SE) SCSI bus

* Assumes 2:1 compression ratio. The capacity and data
transfer rates realized in practice depend on the data set, which
determines the actual compression ratio.

2 Installing Your DLT VS160
Drive
2.1 Chapter Overview
This chapter explains how to configure and install your DLT
VS160 Tabletop Drive or DLT VS160 Internal Drive.
Configuration and installation are not difficult and require only
that you follow the steps and instructions presented in this
chapter.
2.2 Preparation
This section helps you prepare to install your DLT VS160
Tabletop Drive or DLT VS160 Internal Drive.
2.2.1 SCSI Requirements
Your DLT VS160 Drive (tabletop and internal) incorporates a
wide-ultra 160 Low-Voltage Differential (LVD) SCSI bus, but
may also be attached to a Single-Ended (SE) SCSI bus.
Make sure your SCSI host adapter or controller supports these
standards. If you connect the drive to an SE SCSI bus or if
there are SE devices attached to the same SCSI bus, the drive's
performance is limited to the maximum data transfer speed
and maximum cable lengths of the SE bus. The DLT VS160 is
not compatible with a standard differential (Diff) or High-
Voltage Differential (HVD) SCSI bus. If you attach the drive to
a narrow (50-pin) SCSI bus, you must use a customer-supplied
68-pin to 50-pin adapter that terminates the unused 18 pins.
These adapters are sometimes labeled "high-byte termination."
Make sure the total length of the SCSI bus does not exceed the
ANSI SCSI standard of 19 feet (6 meters) for an SE bus, 40 feet
(12 meters) for an LVD SCSI bus with multiple devices, or 82
feet (25 meters) for an LVD SCSI bus with a single device.
2.2.2 Before You Start
Installing your DLT VS160 Tabletop Drive requires no special
tools. You will need a ballpoint pen to change the SCSI ID
switch on the rear panel of the drive. Installing your DLT
VS160 Internal Drive requires only the usual tools needed to

Installing Your DLT VS160 Drive
2-2 DLT VS160 Installation and Operations Manual
install an internal drive in the computer you have chosen to
house the DLT VS160.
If you are installing a DLT VS160 Internal Drive, refer to page
2-9 for instructions.
2.3 Installing your DLT VS160
Tabletop Drive
This section contains step-by-step instructions for installing
your DLT VS160 Tabletop Drive.
2.3.1 Installation Overview
Installing your DLT VS160 Tabletop Drive is fast and easy
when you follow the instructions in this section in the order
presented. Installing your DLT VS160 Tabletop Drive consists
of the following steps, covered in the next few sections:
1. Unpack and check your drive for shipping damage.
2. Select a location near the server or workstation that is to be
the host for your DLT VS160 Tabletop Drive.
3. Set the SCSI ID for your DLT VS160 Tabletop Drive, if
necessary.
4. Shut down and turn off the server or workstation that is to
host your DLT VS160 Tabletop Drive. Remove the power
cable from the selected server or workstation. Turn off and
remove the power cables from all devices attached to the
selected server or workstation.
5. Install an LVD/SE SCSI host adapter in the server or
workstation that is to be the host for your drive, if
necessary.
6. Attach the SCSI cable to your DLT VS160 Tabletop Drive
and SCSI host adapter.
7. Install the terminator on your DLT VS160 Tabletop Drive if
it is the last or only device on the SCSI bus.
8. Attach the power cable to your DLT VS160 Tabletop Drive,
server or workstation, and all attached devices, plug in the
power cable to the nearest power outlet, and turn on all
devices.
9. Check your DLT VS160 Tabletop Drive to make sure it is
working properly.

2.3.2 Unpacking your Drive and Selecting a
Location
Before you begin, clear a desk or table so that you can unpack
your DLT VS160 Tabletop Drive. You also need to select a
location near the server or workstation that is to host your
drive.
Note: If the room in which you are working differs from the
temperature at which your DLT VS160 Tabletop Drive was
shipped or stored by 30° F (15° C) or more, let the drive
acclimate to the surrounding environment for at least 12 hours
before opening the shipping carton.
2.3.2.1 Unpacking your Drive
Before you do anything else, unpack and inspect your DLT
VS160 Tabletop Drive for shipping damage. If you notice any
damage, report it both to and the shipping company
immediately.
Note: Save the packing materials in case you need to move or
ship your drive in the future. You must ship your DLT VS160
Tabletop Drive in the original or equivalent packing materials
or your warranty may be invalidated.
2.3.2.2 Selecting a Location for your Drive
Select a location for your DLT VS160 Tabletop Drive that is
flat, sturdy, level, and close to the host server or workstation. A
desk or table-top is most suitable. Regardless of the location
you choose for your DLT VS160 Tabletop Drive, make sure the
environment is free from dust and excessive temperature and
humidity. See the DLT VS160 Product Specification manual for
acceptable operating temperature and humidity limits.
Be sure to follow these additional guidelines when selecting a
location for your DLT VS160 Tabletop Drive:
• Allow at least 6 inches (15.2 cm) behind the drive for proper
cooling.
• Avoid locations near printers or photocopy machines, both of
which produce paper fiber and other types of dust and
airborne contaminants.
• Do not place your drive on the floor.

Installing Your DLT VS160 Drive
2-4 DLT VS160 Installation and Operations Manual
• Avoid locations near generators, electric motors, audio
speakers, or other sources of magnetic fields. Magnetic
fields can adversely affect your drive and media.
2.3.3 Setting the SCSI ID
Regardless of the number of SCSI devices attached to the
server or workstation that is to be the host for your DLT VS160
Tabletop Drive, each device must have a unique SCSI ID.
Check the SCSI IDs on all other devices on the selected server
or workstation, including the SCSI host adapter, and select an
unused SCSI ID for your DLT VS160 Tabletop Drive. The
factory default SCSI ID is 5. If the drive’s factory default SCSI
ID is not being used by another device on the same SCSI bus,
you do not need to change the SCSI ID.
Figure 2-1: DLT VS160 Tabletop Drive Rear Panel Layout
Note: If you plan to attach the drive to a narrow (50-pin) SCSI
bus, you can only use IDs 0 through 7.
To set the SCSI ID on your DLT VS160 Tabletop Drive, use a
small screwdriver or ball-point pen to press the button above
the SCSI ID display to select the next lower SCSI ID. Press the
button below the SCSI ID display to select the next higher
SCSI ID. Each time you press one of these buttons, the SCSI ID
increases or decreases by one. Press the appropriate button
until the desired SCSI ID appears on the switch display.
