Drive Capacity
The Compaq SLR Drive is a streaming quarter-inch tape cartridge drive that
can read or write 8 GB of compressed data or 4 GB of uncompressed data. The
drive provides low-cost data protection for workstations and entry-level
servers.
Drive Performance
The maximum transfer rate of the Compaq SLR Drive is:
■ 760 kB/second for compressed data

Data Compression
The drive employs the Lempel-Ziv data compression algorithm to compress
data by up to 2 times. This feature is enabled by default but the user may turn
off data compression through the applications software.

Chapter 2
Drive Installation
This chapter provides instructions for installing the drive in:
■ The removable media bay of a workstation or server
■ An external storage unit
NOTE: For the remainder of this user guide, “system” will be used in place of
“workstation” and/or “server”.
Requirements
The user should be aware of the following installation requirements:
Tools
■ Torx T-15 screwdriver
■ Compaq SmartStart and Support CD
Controller
Compaq recommends equipping your system with either a 32-Bit Fast-SCSI-2
Controller or a more current device that provides full support for the Compaq
SLR Drive.
Software
See Chapter 3, “Installing the Software Drivers” to obtain information on what
software you need and where to obtain it.

2-2 Drive Installation
Compaq SLR Tape Drive User Guide
Preparing the System
To prepare your system prior to the installation:
1. Perform a normal system shutdown.
2. Turn OFF the system.
3. Turn OFF all external peripheral devices attached to the system.
4. Disconnect all power cords - first from the AC mains outlets then from
the system and the external peripheral devices.
5. Disconnect the signal cables from the external peripheral devices.
Setting the Drive’s SCSI ID
Since each device on the same SCSI bus must have a unique ID, the user may
need to set the drive’s ID before installation.
IMPORTANT: Your drive has been configured by Compaq with SCSI ID = 6
selected. For more information on setting the drive’s SCSI ID in a SCO
OpenServer environment, see Appendix C, “Drive Configuration Changes”.
The drive’s SCSI ID is selected using a jumper block located at the rear of
the drive.

Installing the Drive
Refer to the documentation supplied with your system for specific instructions
on obtaining access to the removable media bay where you intend to install
your drive.
WARNING: : To reduce the risk of electric shock or damage to the
equipment, disconnect power from the server by unplugging all power cords
from either the electrical outlet or the server.

2-5 Drive Installation
Compaq SLR Tape Drive User Guide
WARNING: Some Compaq servers are capable of producing
energy levels that are considered hazardous. To reduce the risk of
personal injury:
■ Do not attempt to defeat the safety interlocks that prevent
access to hazardous energy.
■ Do not repair accessories and options inside enclosed or
interlocked areas of the system. Repair should be performed
only by individuals who are qualified in servicing computer
equipment and trained to deal with products capable of
producing hazardous energy levels.
WARNING: To reduce the risk of electric shock or damage to your
equipment, do not disable the power cord grounding feature. This
equipment is designed for connection to a grounded (earthed) power
outlet. The grounding plug is an important safety feature.
CAUTION: Electrostatic discharge (ESD) can damage electronic
components. Be sure you are properly grounded before beginning this
procedure. See Appendix B, “Electrostatic Discharge”
for more
information.
IMPORTANT: Your drive shipped with mounting rails attached. The removable
media bays of some systems are configured such that you will need to remove
these rails prior to installing the drive. Refer to the documentation supplied with
your system.

Figure 2-5. Typical Media Bay - No Rails Required

2-8 Drive Installation
Compaq SLR Tape Drive User Guide
1. Obtain access to the removable media bay.
2. Remove the rails from the drive.
3. Slide the drive into the bay.
4. Secure the drive to the bay.
5. Connect a power cable and a SCSI signal cable to the drive.

intermediate power cable connector. See “Installing the Power Cable Extender”
for more information.
Installing the Power Cable Extender
You must install the power cable extender supplied with this kit if you wish to
use one of the intermediate connectors on the power cable. The extender is not
required if you use the last connector on the power cable.
