Scalar 50 Tape Library
Scalar 50
Quick Start Guide
Introduction
The Scalar 50 tape library is an automated storage and retrieval device
consisting of up to two full height tape drives or four half height tape drives
and up to 32 SDLT cartridges or 38 LTO tape cartridges (see figure 1).
This instruction uses the following conventions:
This document explains how to unpack the Scalar 50 tape library and install
it in a standard 19 in. rack. Once the library is unpacked and installed, set
up the library using the instructions in the Scalar 50 User’s Guide PN 81-
81768. This installation procedure will take approximately 4 hours to
complete.
Note: Notes emphasize important information related to the main
topic.
Caution: Cautions indicate potential hazards to equipment and are
included to prevent damage to equipment.
Warning: Warnings indicate potential hazards to personal safety and
are included to prevent injury.
Note: It is recommended to review the entire document prior to
beginning the installation.

Choosing a Location
When choosing an installation site for the Scalar 50, consider the following requirements:
•Rack Space Requirements
•Environmental Conditions
Rack Space Requirements 0Table 1 contains the rack requirements for the Scalar 50 tape library.
Table 1 Rack Requirements
Environmental Conditions 0The installation site must have the following environmental conditions:
• Humidity: 20%-80% non-condensing
• Temperature: 10°C-35°C (50°F-95°F)
• Altitude: -500 to 10,000 feet (-152 to 3048 meters)
Dimensions Scalar 50
Depth 31 in (78.7 cm)
Width 19 in (48.3 cm)
Height 6.75 in (17 cm), 4U
Weight 52 lbs (23.6 kg)
Air Clearance Open 4 in (10 cm) behind unit
for proper air flow

Preparing for the Installation 3
Scalar 50 Tape Library
These environmental conditions apply when the Scalar 50 tape library is in operation.
Preparing for the Installation
Before you begin the installation procedure in this section, make the following
preparations as described in this section:
•Providing Necessary Tools
•Taking ESD Precautions
Providing Necessary
Tools 0Provide the following tools for unpacking and installing the Scalar 50 tape library:
• #1 Phillips screwdriver
• #2 Phillips screwdriver
• #1 flat blade screwdriver
• Allen wrench (2.5mm and 3mm) included in accessory kit
• Antistatic wrist strap included in accessory kit
Taking ESD Precautions 0Some components within the Scalar 50 tape library contain static-sensitive parts. To avoid
damaging these parts while performing installation procedures, always observe the
following precautions:
• Keep the Scalar 50 turned off during all installation procedures.
• Use an antistatic wrist strap (included in the accessory kit).
• Keep static-sensitive parts in their original shipping containers until ready for
installation. Look for the ESD sticker to identify static sensitive parts.
• Avoid touching connectors and other components.
Note: For additional specifications, refer to the Quantum Scalar 50 Series User’s Guide
(PN 81-81768)
Note: Dry climates and cold-weather heating environments have lower relative
humidity and are more likely to produce static electricity.

4Unpacking the Scalar 50 Tape Library
Scalar 50 Quick Start Guide
Unpacking the Scalar 50 Tape Library
This section explains how to unpack the Scalar 50 tape library and move it to its final
installation location.
By following these instructions, you help ensure that the system will continue to be
safeguarded after it arrives at the installation site.
Unpack and remove the following components from the packing materials (see figure 2):
1Remove the accessories kit and set it aside. The accessories kit contains all of the parts
necessary for installing the Scalar 50 in a rack..
2With the help of a second person, lift the library chassis up and out of the shipping
carton.
3Place the library on a table approximately waist high.
Note: Inspect the outer library packaging for damage. If there is any damage evident
on the library packaging, do not continue with the installation and contact
Quantum customer support.
Note: Unpack the library as close to the installation location as possible.
Warning: At least two people are required to move the library chassis.
Caution: Lift the library chassis at the sides. Avoid putting the weight of the
library chassis on the front bezel.

6Installing the Library
Scalar 50 Quick Start Guide
Installing the Library
Installing a Scalar 50 tape library in a rack consists of the following steps:
•Locating the Mounting Position
•Installing the Library
•Initial Configuration
Locating the Mounting
Position 0The Scalar 50 tape library is designed to fit in a standard 19 inch wide rack.
It is important to the library installation to locate the hole pattern in the rack rails and
install clip nuts if required (see figure 3). The library must be installed at the beginning of
the hole pattern to ensure that the library does not interfere with other devices in the rack.
See table 2 for information on common rack hole types.
Table 2 Rack Hole Types Figure Description
Note: The rails within the rack have a hole pattern that repeats throughout the rail. X
marks the screw positions. Install nut clips (included in the accessory kit) on the rails if
necessary.
Square rack holes are the most common type of rack
holes. They can accept either cage nuts which mount
from the back of the rail or clip nuts which clip on from
the side of the rack rail.
Through holes require clip nuts to accept mounting
hardware.
Threaded holes require neither cage or clip nuts to
accept mounting hardware.

Installing the Library 0Installing the Scalar 50 tape library consists of the following steps:
•Installing the Rack Mount Shelves
•Installing the Library Chassis
•Cabling the Library
The following table describes the hardware necessary for installing the Scalar 50 in a rack.
These parts are located in the accessory kit.
Warning: If the rack is empty at the time of installation, do NOT install the Scalar 50
tape library too high in the rack. The weight of the library may cause the
rack to become “top heavy” and unstable if installed in the top of an
empty rack. Begin installing the Scalar 50 tape library from the bottom of
the rack if more than one library is installed.
Note: If this is an upgrade to an existing library system, see Multiple Library Stacks
on page 36.

1Connect the following cables and jumpers included in the accessory kit as shown in
the following figures:
•Figure 16 SCSI full height drives
•Figure 17 Native Fibre Channel full height drives
•Figure 18 SCSI half-height drives
•Figure 19 SAS half-height drives (Surrogate mode SCB only)
•Figure 20 Native Fibre Channel half- height drives
•Figure 21 Stacked Library Configuration
Note: Quantum ships sufficient SCSI cables and terminators with the libraries to
set up two-drives per SCSI bus. One tape drive per SCSI bus may be
necessary for optimum performance. Refer to your tape drive
documentation.
Note: SCSI cable lengths should not exceed:
• 39.37 feet (12 meters) between the host and the library for single drive per bus
installations.
