Warning
This is a Class A product. In a domestic environment this product may cause radio
interference in which case the user may be required to take adequate measures.
European Directive on Waste Electrical and Electronic Equipment (WEEE)
Qualstar encourages its customers to use current recycling practices in order to re-
duce the burden that waste electronic products place on the environment.
If you are retiring a fully functional tape library, you are encouraged to transfer the
functional unit to a new user, thereby extending the useful life of the tape library.
The manufacture of all products requires the consumption of energy. By extending
the life of the tape library, energy is conserved.
In accordance with environmental directives that are being implemented in many
countries (refer to the European Directive on Waste Electrical and Electronic Equip-
ment - WEEE) Qualstar provides customers with “End of Life Instructions” that iden-

511010 Rev. 07-01-19 iii
tify the process for recycling the materials and components that make up a Qualstar
tape library.

Reduction of Hazardous Substances (RoHS)
Qualstar is committed to the implementation of RoHS (Restriction of the use of cer-
tain hazardous substances in electrical and electronic equipment) in accordance with
the European Directive. The effectivity date for compliance is July 1, 2006, at which
time Qualstar will certify that its Tape Library products are compliant with the RoHS

iv 511010 Rev. 07-01-19
standard. With the exception of Lead Based Solder, Qualstar will certify that its
products are free of all other substances listed in the Directive.
Qualstar Tape Libraries fall under the category of “Information Technology Storage
Array Systems” for which the RoHS Directive provides for a lead solder exemption
until the year 2010. Insofar as lead free solders are new to the electronics industry
and no quality or reliability data is available, Qualstar will invoke the lead based sol-
der exemption until such time as industry data verifies that lead free solders are ca-
pable of meeting or exceeding the documented reliability and quality standards
achieved with lead based solders.
Until such time as Qualstar replaces lead based solder with lead free solder, effected
subassemblies must be disposed of appropriately.

2.2 General Description
Models accommodate one or five tape drives (three for the RLS-8350) and have re-
movable storage matrices for tape cartridge storage. There are presently four models
that utilize LTO tape technology. All units operate on internationally available AC
power. Brushless motors are used exclusively. All digital closed-loop servo systems
use magnetic and optical position sensors. The servos automatically calibrate them-
selves, thus eliminating all electrical adjustments. Preventive maintenance is re-
duced to replacing the air filter, when so prompted by the library and removing debris
inside the RLS.
2.2.1 Motion Systems
•The RLS utilizes a four-axis robotic cartridge handling mechanism that
moves cartridges between the storage slots and the tape drives. In the un-
likely event this assembly ever needs replacing, it can be accomplished in
less than 5-minutes.
All axes are driven by brushless DC motors. The motors move the linear
axes with precision lead screws driven by long-life timing belts. Feedback
is provided by hall effect sensors with optical end-of-travel sensing. Car-
tridge gripping is accomplished using a solenoid for simplicity and de-
pendability. The linear axes are riding on linear ball bearings, and the ro-
tating axis is supported on ball bearings. This results in high reliability,
long life, and nearly zero maintenance for the robotics.
2.2.2 Sensors
Optoelectronic Interrupters Sensors
These consist of an LED emitter and an optoelectronic sensor, which produces a digi-
tal output indicating if the light from the corresponding LED is blocked or not. Some
consist of two loose parts, and others have both parts integrated into one housing.
•Z Home Sensor
This sensor pair is mounted on the Z-axis controller board. A feature on
the carriage interrupts this sensor pair when the carriage is moved all the
way back closest to the tape drives.
•Y Home Sensor
This sensor is mounted on the Y-Theta controller board. A feature on the
picker-head interrupts this sensor when the picker-head is moved all the
way down to the lowest extent of its travel.
•Rho Home Sensor
This sensor is mounted on the Carriage controller board. A feature on the
gripper axis interrupts this sensor pair when the gripper is moved all the
way back in the retracted position.

511010 Rev. 07-01-19 Description and Theory of Operation 2-5
Hall Effect Sensors
These are devices that indicate the presence or direction of a local magnetic field.
They are used in the following applications in the library:
•The “Home” position sensor for the Theta axis. The control circuit boards
have a sensor that senses a moving magnet, indicating when the moving
part is at the “Home” end of travel.
•The magazine locks. The locking mechanism moves a magnet in proximity
to a Hall effect sensor on the Control Panel circuit board when the key
lock is in the locked position.
•The I/O port latches. The IO port mechanism moves a magnet in proximity
to a Hall effect sensor on the Control Panel circuit board when the I/O
port is securely latched closed.
•An additional sensor on the Control Panel circuit board is used in combi-
nation with the magazine lock sensor and the I/O port latch sensor to de-
termine which type of magazine or magazine filler is installed.
•Detecting the tape drive carriers or drive filler panels. Hall effect sensors
on the backplane board detect magnets mounted on the tape drive carri-
ers, or the filler panels, to determine what hardware is installed.
•Rotor position sensing for the motors. Each motor is equipped internally
with three Hall effect sensors that are used to commutate the motor wind-
ings, and determine the speed and position of the motor rotor. This is
used to control the position and speed of the axis of the robot that it oper-
ates.
Modulated Optoelectronic Sensors
These are used where the distance between the emitter and detector is greater than
allowed by simple optoelectronic sensor pairs. These sensors consist of an LED emit-
ter, which is modulated, and a detector, which senses the modulated light. One of
these sensor pairs is used to detect the presence of cartridges in the storage slots. A
beam of light is reflected off a reflective surface on the back of the storage slots, and a
detector senses the beam if it is not interrupted. If the beam is interrupted then the
storage slot is determined to be occupied. In addition, there are seven sensor pairs
that are located around the perimeter of the moving carriage. These are used to
sense obstructions to the motion of the carriage, and to aid in judging the success of
cartridge handling. The LED emitter for each pair is located on the sensor boards lo-
cated at the bottom of the carriage, and the detectors are located on the sensor boards
located at the top of the carriage. Any object protruding into the path of the moving
carriage will be detected, and if appropriate, the carriage will stop to prevent a dam-
aging collision. This may result in a fault condition, and a message explaining the
possible causes will be displayed on the control panel. The intensity of the emitters
for these sensor pairs is adjusted during the calibration process to optimize reliabil-
ity.
•Drive

2.2.3 Barcode Reader
A barcode reader is included on all RLS models. The Barcode Reader consists of an
LED light source and an imager and associated electronics. It is mounted on the car-
riage and contains no moving parts. The Barcode Reader can scan all cartridges with-
in the RLS.
2.2.4 Barcode Labels
Barcode labels must conform to ANSI/AIM BCI-1995, Uniform Symbology Specifica-
tion Code 39. Please refer to PIN-040 at www.qualstar.com for more information.
By default, the RLS expects no check characters in each label. All of the labels within
the RLS must match the configuration setting for the check character.
2.3 Component Identification
Most of the major components are common to all models. The number of Tape Drives
depends upon the RLS model and the number of drives installed.
Optional features:
•N+1, hot-swappable power supply modules (automatic e-mail alarm mes-
sage sent via Q-Link when any power supply or fan fails)
•Right side Storage Matrix – adds 60 slots, or 54 if the optional I/O port is
also added (available in RLS-85XX models). The RLS-8350 adds 28 slots
•Additional I/O port in right side Storage Matrix (available in RLS-85XX
models only)
The theory of operation is basically the same for all models, regardless of which
hardware configuration is used.
