Chapter 2 Getting Started
Java Plug-in
The A-Series tape drive utilizes a Web-based interface allowing you to manage the tape drive from a remote workstation on the same network.
The tape drive is configured and managed through Web pages accessible by Internet browser software installed on the host computer.

Resetting System Defaults

Resetting System Defaults
As there is no access to the A-Series tape drive other than the Ethernet port, a mechanism has been implemented to reset the settings to their default values. This is useful if an end user loses the IP address of the A-Series tape drive. The settings can all be set up through the Web manager (i.e. IP settings, root password, ...).
To have the settings set back to their default values:
1 Switch off your tape drive.
2 Disconnect the network cable from the drive.
3 Repeat the following procedure three times:
a Insert a write protected cartridge into the drive.
b Switch on the tape drive.
c After approximately one minute, the cartridge will be ejected.
d Switch off the drive.

4 After the third ejection, connect your network cable and switch your
cartridge write protection on or off (as you need it), then reboot the drive.
You can now set up the drive using the default IP address (10.10.10.10) as the flash memory has been erased.

Warranty Note

Chapter 2 Getting Started
Warranty Note
See the warranty before installing your tape drive. Certain actions taken during installation could void the warranty if not properly conducted.
Generally, the Limited Product and Limited Repair Warranties are contingent upon proper use in the application for which the product is intended; and do not cover the product if you perform any of the following actions:
• Modify the product without the manufacturer’s written approval.
• Subject the product to unusual physical, environmental, or electrical stress, including damage caused by handling or shipping in unapproved containers or packaging.
• Disturb any warranty labels, or the integrity of the product in any other way.
• Remove or damage the serial number label to the extent that warranty status of the product cannot be determined.

Safety, Handling, and ESD Protection

Inappropriate or careless handling of the A-Series tape drives may result in damage to the product. Follow the precautions and directions to prevent damaging the tape drive.

Safety Precautions 2

Quantum A-Series Tape Drives User’s Guide 9
For your safety, follow all safety procedures described here and in other sections of the manual.
1 Power off the system before installing or removing the tape drive to
prevent the possibility of electrical shock or damage to the tape drive. Unplug the unit that contains—or is to contain—the tape drive from AC power to provide an added measure of safety.
2 Read, understand, and observe all label warnings.
Chapter 2 Getting Started
Safety, Handling, and ESD Protection
3 The Pivoting Optical Servo (POS) uses a Class I laser product. This
laser product complies with 29 CFR 1200 and 29 CFR 1910 as applicable on the date of manufacture.
Warning: If you open the tape drive chassis, you may become
exposed to invisible laser emission which could be harmful if you are directly exposed to the beam.

Handling 2

Damage to the tape drive can occur as the result of careless handling, vibration, shock, or electrostatic discharge (ESD). For more details about ESD, see Electrostatic Discharge Protection
.
Caution: Always handle the A-Series tape drive with care to avoid
damage to the precision internal components. Hold the tape drive only by its sides. Never hold the tape drive by inserting fingers into the receiver area on the front of the tape drive. Damage to the receiver area may occur if you lift or carry it in this manner.
Follow these guidelines to avoid damage to the tape drive:
• Always observe prescribed ESD precautions.
• Keep the external tape drive in its anti-static bag until ready to install.
• Always use a properly fitted wrist strap or other suitable ESD protection when handling the tape drive.
• Hold the tape drive only by its sides.
• Do not bump, jar, or drop the tape drive. Use care when transporting the tape drive.
• Always handle the tape drive carefully and gently. A drop of ¼ inch onto a bench or desktop may damage a tape drive.
• Never place the tape drive so that it rests on its front bezel. Always gently place the tape drive flat, bottom side down, on an appropriate ESD-protected work surface to avoid the tape drive being accidentally knocked over.
• Do not pack other materials with the tape drive in its anti-static bag.
• Place the tape drive in the anti-static bag before placing it in a shipping container.
• Do not stack objects on the tape drive.
Quantum A-Series Tape Drives User’s Guide 10
Chapter 2 Getting Started
Safety, Handling, and ESD Protection
• Do not expose the tape drive to moisture.
• Do not place foreign objects inside the tape drive’s receiver area.

Electrostatic Discharge Protection 2

Several electrical components of the A-Series tape drive are sensitive to static electricity and electrostatic discharge (ESD). Even a static buildup or discharge that is too slight to feel can be sufficient to destroy or degrade a component’s operation.
To minimize the possibility of ESD-related damage to the system, the drive’s manufacturer strongly recommends using both a workstation anti-static mat and an ESD wrist strap. When correctly installed and properly used, these devices reduce the buildup of static electricity that might harm the system.
Observe the following precautions to avoid ESD-related problems:
• Leave the tape drive in its anti-static bag until you are ready to install it in the system.
• Always use a properly fitted and grounded wrist strap or other suitable ESD protection when handling the tape drive and observe proper ESD grounding techniques.
• Hold the tape drive only by its sides.
• Place the tape drive on a properly grounded anti-static work surface pad when it is out of its protective anti-static bag.
• Do not use the bag as a substitute for the work surface anti-static pad. The outside surface of the bag may not have the same anti-static properties as the inside surface. It could actually increase the possibility of ESD problems.
• Do not remove covers to use any test equipment to check components on the PCBAs. There are no user-serviceable components on the tape drive.

Data Cartridge Care and Maintenance 3

Observe the following precautions to protect your data:
Always:
• Remove the cartridge from the drive when not in use and store it in its protective case.
• Avoid dropping the cartridge. This can damage components inside the cartridge, possibly rendering the tape unusable. If you drop a tape cartridge, open the cartridge door and make sure that the leader pin is in the correct position.
• Re-tension a dropped cartridge before using.
• Keep the cartridge away from:
• Direct sunlight and heat sources, such as radiators, heaters, or warm air ducts.
• Sources of electromagnetic fields, such as telephones, computer monitors, dictation equipment, mechanical or printing calculators, motors, magnetic tools, and bulk erasers.
Do not:
• Expose the cartridge to dirt, dust or moisture.
• Touch the tape media within the cartridge.
• Bulk erase Ultrium tape cartridges. LTO tape cartridges have prewritten servo patterns that cannot be reformatted by the tape drive. A bulk erase operation would make them unusable.
• Use tape cartridges outside the specified operating conditions: 10
o
C to 40o C, 20% to 80% relative
humidity.
If a tape cartridge has been exposed to conditions outside the specified range, recondition the tape before using in the operating environment by exposing it to the operating environment for a time equal to or greater than the time it was outside the operating environment, up to a maximum of 24 hours. Then re-tension the tape to stabilize the tape pack for better performance.

See the data cartridge appendices in this document (Data Cartridges complete visual inspection instructions for Super DLTtape II data cartridges.
The Web site www.dlttape.com SDLT systems.
The A-Series tape drive performs a power on self-test (POST) each time the tape drive is powered on. POST normally completes in 10 to 15 seconds—when a data cartridge is not in the tape drive— when the unit is powered on. However, if a data cartridge is in the tape drive when the unit is powered on, POST duration is longer, depending on how much tape in the data cartridge may be loaded in the tape drive.
See Front Panel LEDs and Tape Eject LEDs on the front panel.

The tape drive has a thermal sensor located in the tape path. This sensor, which is used to accurately monitor the air temperature in the tape path, issues a TapeAlert warning at 47 degrees C, and detects an overtemp condition when the temperature in the tape path reaches 50 degrees C. When the tape path temperature sensor detects an overtemp condition, the tape rewinds, unloads, and ejects from the tape drive. (As long as the tape drive is not mounted in a tape automation library, the tape ejects.)
If the tape drive is mounted in a tape automation library, the data cartridge rewinds to BOT and unbuckles in preparation for unloading, but does not automatically eject.

A-Series SDLT 600A Tape Drive

The SDLT 600A tape drive incorporates various new state-of-the-art technologies that contribute to the SDLT architecture. Some of these ideas are trademarked, others are patented. The following subsections introduce the important technologies that together, comprise the SDLT 600A tape drive.
A-Series SDLT 600A Tape Drive

Laser Guided Magnetic Recording 1

Pivoting Optical Servo 1

Magneto Resistive Cluster Heads 1

The SDLT 600A tape drives are based on Laser Guided Magnetic Recording (LGMR) technology. LGMR provides a unique combination of the best optical and magnetic technologies, which results in dramatically higher capacities by substantially increasing the number of recording tracks on the data-bearing surface of the media. By recording data magnetically on the data-bearing side of the media and using servo movement optically on the backside, LGMR optimizes highly proven technologies to deliver the most efficient, reliable, and scalable data retrieval solution to the mid-range market.
Pivoting Optical Servo (POS) is a Quantum-invented, optically-encoded servo system, that combines high-density magnetic read/write data recording with laser servo guiding. The POS provides high-duty-cycle applications, which decreases cost and increases user convenience. The POS enables the head to track dynamic variations in tape motion which allows Quantum to provide a track count with an order of magnitude increase over previous products.
Magneto Resistive Cluster (MRC) heads are a densely packed array of small, cost-effective Magneto Resistive (MR) tape heads precisely positioned using advanced thin-film processing technology. SDLT MRC heads provide high wafer usage efficiency resulting in low head costs, are less susceptible to variations in tape speed, yield higher track density and capacity, and provide a multi-channel architecture for increased transfer rate and performance.
Quantum A-Series Tape Drives User’s Guide 28

Modular Design

Advanced Partial Response Maximum Likelihood 1

Advanced Metal Powder Media 1

Positive Engagement Tape Leader Buckling Mechanism 1

Improving on Partial Response Maximum Likelihood (PRML) technology traditionally used in disk drives and communication systems, advanced PRML channel technology, co-developed with Lucent Technologies, brings new levels of performance and capacity to high-performance linear tape products. This provides high-encoding efficiency recording densities for greater capacity and performance that enables SDLT to increase transfer rates and capacity substantially.
Advanced Metal Powder (AMP) media is a state-of-the-art media using durable metal powder technology for recording very high densities of data. The back side of the AMP media receives a specially formulated coating to accept the optical servo tracks. Because the servo information is on the back side of the media, the entire data-bearing side of the media is available for recording data and eliminates the need for pre-formatting. In addition, AMP media meets the needs of multiple generations of the SDLT technology.
The positive engagement tape leader buckling mechanism is a highly robust mechanism that increases data cartridge life and supports the extensive duty-cycle environments found in high-end and automation environments.
This mechanism engages the tape leader upon data cartridge load and disengages it upon data cartridge unload. It uses a solid metal pin attached to the drive leader to link with molded clips permanently attached to the tape leader inside the data cartridge. The Positive Leader Link design makes the buckling of Super DLTtape media a totally reliable mechanical process.
Modular Design
The SDLT 600A tape drive is designed as a total system. The system includes a complex interaction of a number of important components including such items as the tape path, tape heads, media, data cartridge, and host interface.

As shown in figure 10, the SDLT 600A tape drive consists of five distinct modules:
Data Control Module (DCM)
Tape Control Module (TCM)
Front Panel Module (FPM)
Electronic Interface Module (EIM)
Super DLTtape II Data Cartridge (Data Cartridge).
The modular concept makes the SDLT 600A tape drive easy to manufacture and configure. Each module is optimized to perform a specific set of functions and designed to interface with the other modules in a well defined and flexible manner.
The following subsections provide a brief overview of each module.
Note: Despite the deliberate modularity of each module, with the
exception of the FPM, individual users should not
swap
modules. The FPM is the only module that is field replaceable. Customer adjustments to the TCM, DCM, or EIM will void the tape drive’s warranty.
Quantum A-Series Tape Drives User’s Guide 30

Data Control Module 1

Tape Control Module 1

The Data Control Module (DCM) contains several of the functions and features of LGMR technology, which is at the heart of the SDLT technology. Of the five technologies that constitute the LGMR technology, two are in the DCM. These are the POS and the MRC heads.
The main functions of the DCM are to provide the path and guides for all tape motion inside the tape drive and to write data to and read data from the tape. In addition to the POS and MRC heads described in Pivoting
Optical Servo and Magneto Resistive Cluster Heads, the DCM contains a
number of components that interact to perform these functions. These components include:
Advanced head guide assembly
Take-up reel
•Drive motor
Optical servo system
Tape heads.
In addition to its mechanical components, the DCM also contains printed circuit boards that control the functions of the DCM and the tape heads.
The Tape Control Module (TCM) implements the functions required to buckle and unbuckle the tape and control the tape motion. The TCM consists of a variety of components:
TCM Printed Circuit Board Assembly (PCBA)
Base Plate
Data Cartridge Receiver
Positive Engagement Tape Leader Buckling Mechanism
Tape supply motor assembly
Floor plate assembly.
TCM PCBA
The TCM has its own PCBA that controls the functions of the TCM and interfaces with the main controller board in the EIM. By designing the TCM as a distinct module, it allows manufacturing and testing the TCM
Quantum A-Series Tape Drives User’s Guide 31

Modular Design
as a stand-alone module, simplifying the design, manufacturing, and troubleshooting processes.
Base Plate
The SDLT 600A tape drive base plate is an aluminum die casting with precisely machined surfaces. The casting acts as the support platform for the other modules and for the tape drive enclosure. The base plate also includes the precision mounting holes used to install SDLT 600A tape drives into a server or tape library. The SDLT 600A tape drive base plate, and therefore the entire SDLT 600A tape drive, conforms to the 5.25 inch, full-height form factor.
Data Cartridge Receiver
On tape insertion, the data cartridge receiver assembly guides the tape into its operating position, opens the data cartridge door, unlocks the data cartridge brakes, engages the data cartridge drive motor, and secures the tape for operation. On tape ejection, the data cartridge receiver assembly reverses the process and automatically ejects the tape a fixed distance from the front of the tape drive.

Front Panel Module 1

Quantum A-Series Tape Drives User’s Guide 32
The Front Panel Module (FPM) of the system (sometimes referred to as the bezel) performs a number of functions:
Protecting the front of the TCM from physical damage
Channeling airflow through the system
Aligning the data cartridge when it is inserted into the system
Providing system status and information through LEDs
Enabling data cartridge ejection
Modular Design
Delivering the overall cosmetic look of the system.
The FPM is a single module with lenses for the system’s LEDs and a button to activate the drive eject switch. The SDLT 600A tape drive front panel contains no electronics.

Electronic Interface Module 1

Super DLTtape II Data Cartridge 1

The Electronic Interface Module (EIM) is the electronic heart of the tape drive. It provides the main control function for the system and the interface from the system to the host computer, library, or autoloader. The EIM provides the Advanced PRML feature of Quantum’s SDLT technology. See Advanced Partial Response Maximum Likelihood
on
page 29 for a brief description of PRML.
The EIM consists of two major boards: the Integrated Controller Module (ICM), and a separate Host Interface Module (HIM), see figure 10
. The ICM contains the main controller and servo microprocessor, the custom­designed SDLT ASICs, and the cache memory while the HIM implements the interface between the host system and the tape drive. This allows easy configuration of the tape drive to match different host interfaces by simply substituting the appropriate HIM card.
As with the other major modules of the SDLT technology, the EIM is manufactured and tested as a distinct module.
As with all tape technologies, the Super DLTtape II data cartridge is a key part of the overall system. The main function of the data cartridge is to provide the magnetic recording media used by the system to store customer information. The data cartridge also provides the protective casing that allows safe media movement and storage.
From the outside, the Super DLTtape II data cartridge looks very similar to the Super DLTtape I and DLTtape VS1 data cartridges. The basic geometry, write protection switch, and label space are the same. This simplifies the integration of the SDLT 600A tape drive into existing operating environments and into automated tape libraries. The Super DLTtape II data cartridge is easy to recognize; it has a different color than the Super DLTtape I and DLTtape VS1 data cartridges, and contains a distinctive pattern molded into the shell. The DLTtape logo and the product name are also molded into the shell, which ensure you have a genuine Quantum Super DLTtape II data cartridge.

SDLT 600A tape drive Modes
1. The Max-Peak value represents short current spikes drawn for durations of < 50ms. On the 12V supply, the peaks correspond to the pulse-width-modulated switching of the motors. These values are calculated from the average of Peak-ripple-current + 2 sigma, measured at nominal DC voltage.
2. The Max-Mean value is the average of the maximum RMS current drawn during this operating mode. These values are calculated from the average of RMS current + 3 sigma, measured at nominal DC voltage.
3. The typical current is calculated from the average of all RMS current drawn during this operating mode, measured at nominal DC voltage.
4. The Max DC power is calculated from the typical DC power + 3 sigma, measured at nominal DC voltage. This value takes into account that the peak currents on the 5V and 12V do not occur at the same time.
5. The Typical DC power is calculated from the average RMS DC power drawn during this operating mode, measured at nominal DC voltage. This value also takes into account that the peak currents on the 5V and 12V do not occur at the same time.
6. The Max AC power is calculated from the typical AC power in tabletop tape drives + 3 sigma.
7. The Typical AC power is calculated from the average of AC power drawn in tabletop tape drives.
8. These events last < 1 second and occur at a duty cycle of less than 25%.
9. The Max values for each mode are based on the Max-Mean values, since the peak values are of very short duration.
(Common Notes)
(1) Voltage tolerance: 5V ±5%, 12V ±5%; Room temperature 24 °C. AC power measured at 117 V, 60 Hz.
(2) DC Current, MaxMean, and DC/AC Power Max refer to the statistically calculated maximum average
requirement based on a sample population of tape drives. These values do not reflect the peak current or power requirement; this amount is given by the DC MaxPk current.
(3) These results were from the DVT data taken by Percept Technology. Reference the “Power Consumption &
Characterization Test Report” dated 11/28/2005.
(4) Test data set included 12 measurements: 3 measurements of 4 drives.
(5) The 5V “MaxPK” calculated to less than MaxRMS, which does not at first glance make sense. (MaxPK is
calculated at 5.25V, and the switching power supplies need less input current to the same input current.) Instead, the MaxRMS value was substituted.

1. The Max-Peak value represents short current spikes drawn for durations of < 50ms. On the 12V supply, the peaks correspond to the pulse-width-modulated switching of the motors. These values are calculated from the average of Peak-ripple-current + 2 sigma, measured at nominal DC voltage.
2. The typical current is calculated from the average of all RMS current drawn during this operating mode, measured at nominal DC voltage.
3. The Max AC power is calculated from the typical AC power in tabletop tape drives + 3 sigma.
4. The Typical AC power is calculated from the average of AC power drawn in tabletop tape drives.
5. These events last < 1 second and occur at a duty cycle of less than 25%.
6. The Max values for each mode are based on the Max-Mean values, since the peak values are of very short duration.
(Common Notes)
(1) Voltage tolerance: 5V ±5%, 12V ±5%; Room temperature 24 °C. AC power measured at 117 V, 60 Hz.
(2) DC Current, MaxMean, and DC/AC Power Max refer to the statistically calculated maximum average
requirement based on a sample population of tape drives. These values do not reflect the peak current or power requirement; this amount is given by the DC MaxPk current.
(3) These results were from the DVT data taken by Percept Technology. Reference the “Power Consumption &
Characterization Test Report” dated 11/28/2005.
(4) Test data set included 12 measurements: 3 measurements of 4 drives.
(5) The 5V “MaxPK” calculated to less than MaxRMS, which does not at first glance make sense. (MaxPK is
calculated at 5.25V, and the switching power supplies need less input current to the same input current.) Instead, the MaxRMS value was substituted.

SDLT 600A Tape Drive Recording Method 1

The SDLT 600A tape drive uses the Partial Response Maximum Likelihood (PRML) 32/33 encoding method for reading/writing SDLT 600A tape drive format. It uses the same algorithm for reading SDLT 220, SDLT 320, and the DLT VS160 tape drive formats.
Environmental Specifications
The SDLT 600A tape drive operates in environments that include general offices and work spaces with systems capable of maintaining standard comfort levels.
The following subsections provide the environmental specifications for the SDLT 600A tape drives (both the internal and the tabletop configurations). For long-term trouble-free operation, the manufacturer strongly recommends that SDLT 600A tape drives be used in a clean, smoke-free environment.

Air Flow Requirements 1

The internal tape drive requires adequate air flow to dissipate the heat resulting from continuous drive operation. Specifically, the air flow must be sufficient to keep the tape path temperature below 50 °C.
To allow enough air into the tape drive to keep the tape path below this temperature, it is important to keep the cooling holes in the rear and the grill in the front of the tape drive clear of any obstructions that may hinder the air flow.
Note: It is also important to limit the ambient air temperature to no
greater than 40 °C.

Data Cartridge Handling Guidelines

Note: The Super DLTtape II data cartridge has a keying feature to
ensure you cannot load it into a previous generation DLT tape drives.
Data Cartridge Handling Guidelines
By following general handling procedures, conducting careful visual inspections of data cartridges on a regular, ongoing basis, and being certain to store data cartridges within their environmental limits, you will greatly reduce any chance that you will experience problems with your data cartridges or cause damage to your Super DLTtape system. Respect your media as much as you do your data.
Following these general handling guidelines:
Always keep each data cartridge in its protective plastic case when it is not in the tape drive.
When carrying data cartridges in their cases, always orient the cases so that the grooves in the cases interlock. This prevents the cases from slipping apart and falling.
Never stack the data cartridges in a stack of more than five.
When placing data cartridges in archival storage, be certain you stand each data cartridge vertically.
Quantum A-Series Tape Drives User’s Guide 54
Data Cartridge Handling Guidelines
Do not carry data cartridges loosely in a box or any other container. Allowing data cartridges to jostle together exposes them to unnecessary physical shock.
Always observe the proper environmental conditions for storing data cartridges. Refer to the data cartridge reference card supplied with each data cartridge. The ambient operating environment for the data cartridge is
Temperature 10
°C to 40 °C (50 °F to 104 °F)
Relative Humidity 20% to 80% (non-condensing)
Note: If storage or transportation of a data cartridge has exposed
it to conditions outside the ambient values shown above, you should condition the data cartridge to its operating environment for a 24-hour period.
Maintain clean and smoke-free operating and storage environments.
Never expose the data cartridge to moisture or direct sunlight.
Do not place data cartridges on or near devices that may produce magnetic fields, such as computer monitors, motors, or video equipment. Such exposure can alter or erase data on the media.
Avoid unnecessary opening of the data cartridge door; this may expose the media to contamination or physical damage.
Do not touch or allow direct contact with the media or tape leader. Dust or natural skin oils can contaminate the data cartridge and impact media performance.
A dropped data cartridge may have dislodged, loosened, or damaged internal components. If you drop a data cartridge, give it a thorough visual inspection, as described in Data Cartridge Inspection
Procedure.
Never apply adhesive labels or “sticky” notes on the top, side, or bottom of your Super DLTtape II data cartridge. Only use the slide-in type label provided with each data cartridge and slide it into the label slot on the data cartridge.
Do not use graphite pencils, water-soluble felt pens, or other debris­producing writing instruments on your labels. Never erase a label— replace it.
Quantum A-Series Tape Drives User’s Guide 55
Be certain you place the unused data cartridge labels in the protective box so that you do not inadvertently pick them up along with the data cartridge during subsequent usage. A static electricity charge on a data cartridge may cause a label to cling to the data cartridge. A label that is accidentally inserted into the tape drive along with a data cartridge can prevent the hub reel and drive gear from meshing.
Follow all data cartridge handling instructions that accompany your data cartridges or tape drive.
Note: Always remove the data cartridge from the drive prior to
powering down the drive. This ensures that the file system stored on the tape is consistent and that the tape in the tape path is not damaged when the unit is powered up.

Data Cartridge Inspection Procedure

Data Cartridge Inspection Procedure
Follow the Visual Mechanical Inspection (VMI) procedures described in this subsection. These steps will help you identify any potential data cartridge problems, and will prevent accidental loss of data or damage to your tape drive.
You should do an inspection if any of these conditions occur:
As a general practice whenever you change or load a new data cartridge.
If a data cartridge is dropped or subjected to some hard physical shock.
If the SDLT 600A tape drive becomes inoperable after loading a data cartridge.
If you receive a shipment of data cartridges that show any sign of shipping damage.
Follow these steps to visually inspect a Super DLTtape II data cartridge:
1 Remove the data cartridge from its protective plastic case.

Tape Cartridge Care and Maintenance 2

Observe the following precautions to protect the data on your Ultrium tape cartridges:
Always:
• Remove the cartridge from the drive when not in use and store it in its protective case.
• Avoid dropping the cartridge. This can damage components inside the cartridge, possibly rendering the tape unusable. If you drop a tape cartridge, open the cartridge door and make sure that the leader pin is in the correct position.
• Re-tension a dropped cartridge before using.
• Keep the cartridge away from:
• Direct sunlight and heat sources, such as radiators, heaters, or warm air ducts.
• Sources of electromagnetic fields, such as telephones, computer monitors, dictation equipment, mechanical or printing calculators, motors, magnetic tools, and bulk erasers.
Do not:
• Expose the cartridge to dirt, dust or moisture.
• Touch the tape media within the cartridge.
• Bulk erase Ultrium tape cartridges. LTO tape cartridges have prewritten servo patterns that cannot be reformatted by the tape drive. A bulk erase operation would make them unusable.
• Use tape cartridges outside the specified operating conditions: 10
o
C to 40o C, 20% to 80% relative
humidity.
If a tape cartridge has been exposed to conditions outside the specified range, recondition the tape before using in the operating environment by exposing it to the operating environment for a time equal to or greater than the time it was outside the operating environment, up to a maximum of 24 hours. Then re-tension the tape to stabilize the tape pack for better performance.

When this happens, the drive can experience excessive errors while reading or writing, and illuminate the amber Status LED continuously during operation. This means that the drive needs to be cleaned.
The LTO cleaning cartridge has the same dimensions as the tape cartridge and contains an LTO Cartridge Memory (LTO-CM), but is loaded with cleaning media instead of recording media. Always keep the LTO cleaning cartridge in its protective case when not in use.
To clean the A-Series LTO-3A tape drive:
1 Load an LTO cleaning cartridge into the tape drive.

Cleaning the Tape Mechanism
2 Observe that both the Status and Activity LEDs are on steady during
the cleaning process.
Note: If the A-Series LTO-3A tape drive does not recognize the
cartridge as an LTO cleaning cartridge, the drive stops the cleaning process and ejects the cartridge.
3 After the cleaning process completes, depending on the drive
configuration, either:
a The drive automatically ejects the LTO cleaning cartridge, or
b You must press the tape load/unload button to eject the LTO
cleaning cartridge.
4 Write the date on the cartridge label for future reference.
Each time you use the LTO cleaning cartridge, the cleaning media advances to a new, unused section. After approximately 50 cleanings, all of the media will be used up and the A-Series LTO-3 tape drive:
• Turns on the green
• Fast flashes the amber

• Ejects the LTO cleaning cartridge
Always discard used-up LTO cleaning cartridges.
Note: If the amber

Performing an Emergency Reset and Cartridge Eject

Performing an Emergency Reset and Cartridge Eject
If the A-Series LTO-3A tape drive stops communicating with the host computer, use the following procedure to reset the drive and eject a cartridge (if necessary).
Caution: When you perform an emergency reset and cartridge
eject, any data in the drive or host buffers will not be written to the tape and the tape record may not be correctly terminated with an end-of-data mark. If the end­of-data mark is not written to the tape, you will not be able to append any data to that tape unless you overwrite the existing data on the tape.
To perform an emergency reset, hold down the load/unload button between 5 to 15 seconds, and then release it.
