2.3 SDLT 220/320 Technology
SDLT 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 tape drive system.
2.3.1 Laser Gu ide d M agnetic Reco rdi n g
The SDLT system (Figure 2-1 and Figure 2-2) is based on Quantum’s 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 substa ntially inc reasing 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 servoing optically on the backside, LGMR
optimizes highly proven technologies to deliver the most efficient, reliable and
scalable data backup solution to the mid-range market.

2.3.2 Pivoting Optical Servo
Pivoting Optical Servo (POS) is a Quantum-invented, optically-encoded servo
system, which combines high-density magnetic read/write data recording with
laser servo guiding. The POS is designed for 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 current DLT products.
2.3.3 Magneto Resistive Cluster Heads
Magneto Resistive Cluster (MRC) heads are a densely packed array of small, costeffective Magneto Resistive (M R ) 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 temperature and
humidity, yield higher track density and capacity, and provide a multi-channel
architecture for increased transfer rate and performance.

SDLT 220 and SDLT 320 Produ ct Manual CHAPTER 2: SDLT 220/320 Product Information
2.3.4 A dvanced Partial Response Max imum Likelihood
Improving on Partial Response Maximum Likelihood (PRML) technology
traditionally used in disk drives and communication systems, Quantum’s advanced
PRML channel technology was co-developed with Lucent Technologies to bring
new levels of performance and capacity to high-performance linear tape products.
This provides high-encoding efficiency recording de nsities for gre ater capacity
and performance that enables SDLT to substantially increase transfer rates and
capacity.
2.3.5 Advanced Metal Powder Media
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 eliminate
the need for pre-formatting. In addition, AMP media has been designed to meet the
needs of multiple generations of the SDLT technology.
2.3.6 Positive Engagement
Positive engagement is a highly robust tape leader-buckling mechanism that
increases cartridge life and supports the heavy duty-cycle environments found in
high-end and automation environments.
This mechanism engages the tape leaders upon cartridge load and disengages them
upon cartridge unload. It uses a solid metal pin that is attached to the drive leader
to link with molded clips that are permane ntly attached to the ta pe leader inside the
cartridge. The Positive L eader Link design makes the buckling of Super DLTtape I
media a totally reliable mechanical process.
In addition to supporting Super DL Ttape I data cartridges, the buckling mechanism
also supports existing DLTtape IV data cartridges to ensure complete backwardread compatibility.

2.4 SDLT 220/320 Modular Design
SDLT 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, cartridge, and host interface.
SDLT is organized into five distinct modules (Figure 2-3) as follows:
• Data Control Module (DCM)
• Tape Control Module (TCM)
• Front Panel Module (FPM)
• Electronic Interface Module (EIM)
• Super DLTtape I Data Cartridge
The modular concept makes the SDLT system 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 data cartridge and the FPM, individual
users should not “swap” modules. The data cartridge and
2-6 March 20 04 81-850 02-01

the FPM are the only two modules that are field
replaceable. Customer adjustments to the TCM, DCM, or
EIM are not allowed, and will void the drive’s warranty.
2.4.1 D at a C ont rol Modul e
The Data Control Module (DCM) contains several of the functions and features of
Quantum’s LGMR technology, which is at the heart of the SDLT technology. Of
the five technologies that constitute the LGMR technology, two are found 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 the tape
motion inside the drive and to write data to and read data fr om the tape. In addition
to the POS and MRC heads described in Section 2.3.2, “Pivoting Optical Servo”
on page 2-4 and Section 2.3.3, “Magneto Resistive Cluster Heads” on page 2-4,
the DCM contains a number of components that interact to perform these
functions. These components include the advanced head guide assembly, take-up
reel, drive motor, the optical servo system, and the tape heads.
The SDLT system tape path, from the first tape guide through the take up reel and
motor, has been simplified and improved from the previous DLT systems. The
addition of servo technology in the POS system has allowed Quantum engineers to
reduce the number of tape guides from six to four. This provides a simpler tape
path in the SDLT tape drive, improving performance and reliability.
In addition to its mechanical components, the DCM also contains printed circuit
boards that control the functions of the DCM and the tape heads.

2.4.2 Tape Control Module
The T ape 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 PCBA (Printed Circuit Board Assembly)
• Base Plate
• Cartridge Receiver
• Positive Engagement Tape Leader Buckling Mechanism.
Other components include the tape supply motor assembly and the floor plate
assembly.
TCM PCBA
The TCM has its own Printed Circuit Board Assembly (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 the TCM to be manufactured
and tested as a stand-alone module, simplifying the design, manufacturing and
troubleshooting processes.
Base Plate
The SDLT base plate is an aluminum die casting with precisely machined surfaces
that acts as the support platform for the other modules and for the drive enclosure.
The base plate also includes the precision mounting holes used to install SDLT
tape drives into a server or tape library. The SDLT base plate, and therefore the
entire SDLT drive, conforms to the 5.25 inch, full-height form factor. This means
that SDLT tape drives are a little shorter , at the s tandard 8 inche s, than the previou s
generation DLT products.
Cartridge Receiver
On tape insertion, the cartridge receiver assembly guides the tape into its operating
position, opens the cartridge door, unlocks the cartridge brakes, engages the
cartridge drive motor, and secures the tape for operation. On tape ejection, the
2-8 March 20 04 81-850 02-01
SDLT 220 and SDLT 320 Produ ct Manual CHAPTER 2: SDLT 220/320 Product Information
cartridge receiver assembly reverses the process and automatically ejects the tape a
fixed distance from the front of the drive. There is no longer a manual lock and
release handle to operate when loading and unloading the cartridge. This “soft
load” capability makes SDLT easier for customers to use in both stand-alone
applications and automated tape libraries.
Positive Engagement Tape Leader Buckling Mechanism
This design for SDLT uses a solid metal pin attached to the drive leader which
positively links with molded clips that are permanently attached to the tape leader
inside the cartridge. The buckling mechanism is responsible for engaging the tape
leaders upon cartridge load and disengaging them on cartridge unload.
The SDLT buckling mechanism has been designed to work with the new leaders of
the Super DLTtape design as well as the leaders of the previous DLTtape design,
allowing backward-read compatibility (BRC) of DLTtape IV cartridges in the
SDLT system.
2.4.3 Front Panel Module
The Front Panel Module (FPM) of the system (sometimes referred to as the bezel)
performs a number of functions. The functions of the SDLT FPM include:
• Protecting the front of the TCM from physical damage
• Channeling airflow through the system
• Aligning the cartridge when it is inserted into the system
• Providing system status and information through LEDs
• Enabling cartridge ejection
• 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. Unlike previous generations of DLT, the SDLT
front panel contains no electronics.

2.4.4 Electronic Interface M odule
The Electronic Interface Module (EIM) is the electronic heart of the SDLT system.
It provides the main control function for the system and the interface from the
system to the host computer. The EIM provides the Advanced PRML feature of
Quantum’s SDLT technology; advanced PRML is described in “Advanced Partial
Response Maximum Likelihood” on page 2-5.
The EIM consists of two major boards: the Integrated Controller Module (ICM),
and a separate Host Interface Module (HIM). The ICM contains the main
controller and servo micro-processor, the custom-designed SDLT ASICs and the
cache memory while the HIM implements the interface between the host system
and the drive. This allows easy configuration of the 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 has been
designed to be manufactured and tested as a distinct module.
2.4.5 S uper DLTtape I Data Ca rt ri dge Module
As with all tape technologies, the Super DLTtape I 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 cartridge that allows the media to be
removed and stored safely.
From the outside, the Super DL Ttape I data cartridge looks very similar to the
DLTtape IV data cartridges. The basic geometry, write protection switch, and label
space are unchanged from the DLTtape IV data cartridge. This simplifies the
integration of SDLT into existing operating environments and into automated tape
libraries. The Super DLTtape I data cartridge is easy to recognize; it has a different
color than the DLTtape IV data cartridge and contains a distinctive pattern molded
into the shell.
The Super DLTtape I data cartridge has a new, more rugged design that includes a
thicker internal circular wall surrounding the media and more structural ribbing to
increase overall cartridge resilience and reduce potentia l damage to the cartridge if
it should be dropped. New, wear-resistant materials reduce the potential for debris
generation and increase the life of the cartridge.

2.7 TapeAlert
SDLT drives are delivered with TapeAlert features built in. The internal SDL T
firmware constantly monitors the device’s hardware and media, checking for
errors and potential difficulties. Any problems identified are flagged on the SCSI
log page, where 64 bytes have been reserved for use by T apeAlert.
After a backup has been completed, the TapeAlert-compatible backup application
will automatically read the device’s TapeAlert SCSI log page to check for any
problems. If an error is flagged, your backup software displays a clear warning
message on your screen, and adds the TapeAlert messages to its logs. These
messages are standard across all applications that support TapeAlert, and are
designed to give clear explanation of the problem and suggested resolution. For
example, if you were attempting to back up onto an expired tape, you would see
the following message:
WARNING: The tape cartridge has reached the end of its useful life:
Copy any data you need to another tape.
Discard the old tape.

3.1.7 Head Life and MTBF
Mean time between failures (MTBF) for the overall tape system is projecte d to be
250,000 hours, not including the heads. Head life is a minimum of 30,000 tape
motion hours and an average of 50,000 tape motion hours.
3-4 March 20 04 81-850 02-01
SDLT 220 and SDLT 320 Product Manual CHAPTER 3: Drive Specifications
To provide access to backup tapes written on DLTtape tape drives, the SDLT drive
will read, but not write, DLTtape IV cartridges; this is known as backward-read
compatibility (BRC) mode. The drive uses a different head while operating in
BRC mode; the BRC head life is guaranteed to be a minimum of 10,000 tape
motion hours.
NOTE: Quantum Corporation does not warrant that predicted
MTBF is representative of any partic ular unit ins ta lled for
customer use. Actual figures vary from unit to unit.
3.1.8 Media Durability
Media durability is 1,000,000 passes; a media pass is defined as movement of the
tape head over the surface of the media (in either direction). Alternatively stated,
each DLTtape IV and Super DLTtape I media provides 250 full tape uses; a full
tape use (end-to-end) is considered to be the type of operation that occurs when a
customer writes very large filesets to the tape.

3.2.3 Current and Power Requirements
T able 3-1 1 on page 3-11 lists the current and power requirements for both versions
of the tape system (internal and tabletop). The tabletop version requires AC power .
The highest current (and power) is drawn during the native write modes and
backward-read compatibility (BRC) rea d modes, so they are outlined in
Table 3-11. Standby is measured with the tape loaded and tensioned or
untensioned, and Idle is measured with power on with no tape loaded. (The
power drawn in these two modes is similar enough that they are listed together.)
Power-up current surges are less than those encountered during motor
accelerations, and so are not listed separately .
NOTE: In Table 3-11, the current and DC power values are
relevant to the internal drive, while the AC power values
are relevant to the tabletop drive.

systems (both the internal and the tabletop configurations). For long-term troublefree operation, it is strongly recommended that SDLT tape drives be used in a
clean, smoke-free environment.
3.3.1 Air Flow Requirements
Adequate air flow must be provided for the internal tape drive to dissipate the heat
resulting from continuous drive operation. Specifically, the air flow must be
sufficient to keep the tape path temperature below 52°C.
NOTE: It is important to realize that the amount of air flow
provided for the tape drive determines the maximum
ambient temperature in which the drive can operate.
For more details about specific temperatures inside the drive at specific locations,
refer to a separate document, SDLT 220 and SDLT 320 Design and Integration
Guide, 81-81148-01.

4.1 Safety, Handling, and ESD Protection
Inappropriate or careless handling of tape systems may result in damage to the
product. Follow the precautions and directions to prevent damaging the tape
system. In addition, follow the pre-installation guidelines to ensure that you have
the correct hardware for your system configuration.
4.1.1 Safety Precautions
For your safety, follow all safety procedures described here and in other sections of
the manual.
1. Remove power from the system before installing or removing the tape dri ve to
prevent the possibility of electrica l s hock or damage to the ta pe drive . Unplug
the unit that contains or is to contain the drive from AC power to provide an
added measure of safety.
2. Read, understand, and observe all label warnings.
3. The POS uses a Class I laser product. This laser product complies with 21
CFR 1040.10 as applicable on the date of manufacture.
CAUTION: While the tape drive chassis is open, you can be exposed
to invisible laser radiation; take care to avoid direct
exposure to the beam.

SDLT 220 and SDLT 320 Product Manual CHAPTER 4: Installing Your Tape Drive
4.1.2 Handling
Damage to the tape system can occur as the result of careless handling, vibration,
shock, or electrostatic discharge (ESD). For more details about ESD, refer to
“Electrostatic Discharge Protection” on page 4-4.
Follow these guidelines to avoid damage to the drive:
CAUTION: Always handle the tape system with care to avoid
damage to the precision internal components. Do not
place hands inside the tape drive’s receiver area. Hold
the internal tape drive by the sides or the tabletop drive
by the bottom. Never hold either drive by inserting
fingers into the receiver area on the front of the drive.
Damage to the receiver area may occur if the drive is
lifted or carried in this manner.
• Always observe prescribed ESD precautions.
• Keep the internal drive in its anti-static bag until ready to install.
• Always use a properly fitted wris ts tra p or othe r s uita ble ES D protec tion when
handling the drive.
• Hold the internal tape drive only by its sides.
• Do not bump, jar, or drop the drive. Use care when transporting the drive.
• Always handle the drive carefully and gently. A drop of ¼ inch onto a bench
or desktop may damage a drive.
• Never place the tape drive so that it rests on its front bezel. Always gently
place the drive flat, printed circuit board (PCB) side down, on an appropriate
ESD-protected work surface to avoid the drive being accidentally knocked
over.
• Do not pack other materials with the drive in its anti-static bag.
• Place the drive in the anti-static bag before placing it in a shipping container .
• Do not stack objects on the drive.
• Do not expose the drive to moisture.
• Do not place foreign objects inside the tape system’s receiver area.

4.1.3 Electrostatic Discharge Protection
Several electrical components of the tape system 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, we strongly
recommend using both a properly installed workstation anti-static mat and a
properly installed ESD wrist strap. When correctly installed, these devices reduce
the buildup of static electricity that might harm the system.
Observe the following precautions to avoid ESD-related problems:
• Use a properly installed anti-static pad on your work surface.
• Always use a properly fitted and grounded wrist strap or other suitable ESD
protection when handling the tape system and observe proper ESD grounding
techniques.
• Hold the drive only by its sides. Do not touch any components on the printed
circuit board assembly (PCBA).
• Leave the drive in its anti-static bag until you are ready to install it in the
system.
• Place the 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 of the bag may not have the same anti-static properties as the inside. It
could actually increase the possibility of ESD problems.
• Do not use any test equipment to check components on the PCBA. There are
no user-serviceable components on the drive.

SDLT 220 and SDLT 320 Product Manual CHAPTER 4: Installing Your Tape Drive
4.2 Pre-Installation Guidelines
Before you begin, check the contents of the box, record the applicable numbers,
check for SCSI controller and cable compatibility, and confirm software and
operating system compatibility. Finally, check the drive to make sure it is operating
properly before installing it in a system.
1. Unpack and review the contents of the box to ensure that nothing has been
damaged. If items have been damaged, contact your drive provider.
2. Record the model and serial number of the SDLT system. These numbers
provide specific information about the SDLT system and will be very helpful
if you have to contact technical support. These numbers can be found on the
bottom of the drive enclosure.
The Model Number is a number and letter string usually beginning with the
letters “TR.”
Model Number: TR
The Serial Number is an 8-character string usually beginning with the letters
“MX.”
Serial Number: MX
3. Check the enclosed SCSI cable to ensure it is compatible with the SCSI
controller card in the host computer.
4. Check the SCSI interface on the host computer to ensure that it is compatible
with the drive. Possible interfaces include MSE single-ended, MSE low
voltage differential, or high voltage differential. Remember that a single ended
or low voltage dif ferential drive will only work with a sys tem that has an MSE
controller card installed; and a high voltage differential drive will only work
with a differential controller card.
5. Confirm that your back-up software and operating system are compatible with
the drive. Refer to www.superdlttape.com for the most current compatibility
information.

4.3 Configuring and Installing an Internal Tape Drive
This section provides information for configuring and installing a tape drive into a
system. See “Configuring and Installing a Tabletop Drive” for information on
configuring and installing a tabletop tape drive.
CAUTION: Before you begin, review the safety, ESD, and handling
precautions described at the beginning of this chapter to
avoid personal injury or damage to equipment.
Configuration for the SDLT system includes the following:
• Setting the SCSI ID for the drive (default = SCSI ID 5).
• Configuring the drive to provide TERMPWR.
• Setting the configuration jumper (default = wide SCSI enabled).
If you want to change any of the settings, refer to the applicable subsection;
otherwise proceed directly to the tape drive’s installation procedures in “Installing
the Internal Tape Drive” on page 4-11.
4-6 March 20 04 81-850 02-01
SDLT 220 and SDLT 320 Product Manual CHAPTER 4: Installing Your Tape Drive
4.3.1 Setting the Internal Drive SCSI ID
Each device on the SCSI bus must have a unique SCSI ID address assigned to it.
For specific recommendations for assigning SCSI IDs, refer to your system or
SCSI controller documentation.
The SCSI ID is set using jumpers on a set of pins at the rear of the drive. This
section discusses setting the SCSI ID on the internal drive via the jumper block.
Table 4-1 and Table 4-2 show the SCSI ID address and jumper settings.
Figure 4-1 shows the empty jumper block that you use to set the SCSI ID. If you
decide it is necessary to change the tape drive’s SCSI ID, use your fingers to move
the jumpers to the pattern corresponding to the ID you want (see Figure 4-1 and
the related table of SCSI jumper s ettings in Table 4-1 on page 4-8 and T able 4-2 on
page 4-10).
Figure 4-1. Detail of the Empty SCSI ID Jumper Block
Internal drives can be configured for SCSI ID addresses that range from 0 to 15 in
one of two ways:
• Jumper the 10-pin SCSI ID block located on the back of the drive (Figure 4-2
on page 4-9), OR
• In a library setting, you can set the IDs through firmware. (The firmware
default = SCSI ID 5 and assumes no jumpers are installed on the jumper
block.)
The default setting for the tape drive is 5; the host adapter setting is typically SCSI
ID 7. If you choose to omit all jumpers from the SCSI ID block, the tape drive will
use the default setting of 5.

4.3.2 Configuring the Internal Drive for TERMPWR
A SCSI bus must be terminated at each end of the bus. All signals not defined as
RESERVED, GROUND, or TERMPWR shall be terminated exactly once at each
end of the bus. At least one device must supply terminator power (TERMPWR).
To enable TERMPWR, install the jumper across Pins 1 and 2 on the TERMPWR
jumper block (Figure 4-2 on page 4-9). Remove the jumper to disable
TERMPWR. Pins 3 and 4 on this block are reserved and require no jumpering.
4.3.3 Configurin g the Internal Drive for Narro w SCSI
The 8-pin Configuration Jumper block allows you to enable or disable the wide
SCSI bus. The default setting is for the wide SCSI bus to be enabled; there is no
jumper across Pins 1 and 2 when wide SCSI is enabled (Figure 4-2 on page 4-9).
To disable wide SCSI, install a jumper across Pins 1 and 2. Pins 3 through 8 are
reserved and require no jumpering.
4.3.4 Ins ta lling t h e In t er nal Tape Drive
Installing the tape drive requires securing the drive in its bay or chassis and
connecting SCSI bus and power cables, as described in “Securing the Internal Tape
Drive” below. When you have finished mounting and installing the drive, proceed
directly to “Confirming the Installation” on page 4-24 to confirm the installation.
Two perspective views of the internal tape drive are shown in Figure 4-4.

Securing the Internal Tape Drive
This section describes how to mount and secure the drive in the system.
NOTE: In some system configurations it may be more convenient
to connect the SCSI bus and power cables to the drive
before securing it in the system.
Because of the variety of mounting possibilities for tape drives, the instructions
presented here are general in nature. They should be used only as a guide for
mounting the drive in your system.
Mount the drive in the system by performing the following steps:
1. Position the drive in the system and align the drive mounting holes (side or
bottom) with those in the system. Figure 4-5 on page 4-13 shows the
mounting locations and dimensions for the drive.
C
AUTION: The screws used to mount the tape drive must be #6-32
UNC-2B screws. This type of screw is exactly the proper
length and will not damage the tape drive.
4-12 March 20 04 81-850 02 - 01
SDLT 220 and SDLT 320 Product Manual CHAPTER 4: Installing Your Tape Drive
2. Using four #6-32 UNC-2B screws, secure the tape drive in the bay or chassis.

Connecting the Internal Drive Cables
The three connectors on the back of the internal SDLT drive that are discussed in
this section are: 1) SCSI, 2) power, and 3) optional library/loader connectors. For
the tabletop model, typical connectors (power cords) are shown in Figure 4-8 on
page 4-24.

CHAPTER 4: Ins talling Your Tape Drive SDLT 220 and SDLT 320 Prod uc t Ma nu al
Pin assignments for the three possible SCSI connectors are listed in a series of
tables: Multimode Single-Ended (MSE) Single Ended (SE) mode in Table 4-3 on
page 4-15, MSE Low Voltage Differential (LVD) mode in Table 4-4 on page 4-17,
and High Voltage Differential (HVD) mode in Table 4-5 on page 4-18. Pin
assignments for the power connector are listed in Table 4-6 on page 4-20.
1. Prior to connecting the SDLT drive to the host computer, make sure the drive
and computer are turned OFF.
2. If you are connecting several devices to the SCSI bus, connect only the drive
to the host computer at this time. Conf irm that the host compute r and drive are
communicating correctly before adding additional devices.
3. The SCSI bus must be terminated at each end. This drive may need to be
terminated:
if the SDLT drive is the only device connected to the SCSI bus, OR
if the SDLT drive is one of several devices connected to the SCSI bus,
and it is the last device connected to the SCSI bus.
4. If the answer to step 3 was affirmative, attach a “Y” connector to the drive’s
SCSI connector; then attach the SCSI cable to one leg of the “Y” and attach
the terminator to the other leg. Carefully connect the cables, to avoid bending
or damaging the connector pins.
5. Attach the power cables to the drive. Check the SCSI cable and termination
connections and ensure that they are attached correctly and seated firmly.
NOTE: The “Y” connector is not provided by Quantum.
Optional Loader Connector
The 8-pin optional loader connector provides signals to be used when the tape
drive is part of a loader/library configuration. Figure 4-6 on page 4-15 shows the
location of this connector; pin assignments for the loader connector are listed in
Table 4-7 on page 4-20.

4.4 Configuring and Inst alling a Tabletop Drive
This section provides instructions for configuring and installing the SDLT tabletop
drive.
4.4.1 Configuring the Drive
Figure 4-7 shows the location of the controls and connectors for the tabletop drive.
This model tape drive is normally configured to meet customer specifications
before leaving the factory, so should not require any internal configuration changes
on-site.
Figure 4-7. Back Panel of the Tabletop Model
SCSI ID The SCSI ID default for the tabletop drive is set to 3; the drive can be
configured for SCSI ID addresses that range from 0 to 15 using the SCSI ID
pushbutton. Press the button above or below the ID number display to set the
81-85002-01 March 2004 4-21
CHAPTER 4: Ins talling Your Tape Drive SDLT 220 and SDLT 320 Prod uc t Ma nu al
desired SCSI ID. The top button increases the ID number, the bottom button
decreases the ID number.
TERMPWR The TERMPWR setting for the tabletop drive is preconfigured at
the factory according to specific customer requirements. TERMPWR is not
selectable on-site.
4.4.2 Ins ta lling t he Tabletop Dri ve
Tabletop drive installation consists of connecting SCSI bus and power cables.
Figure 4-7 on page 4-21 shows the location of the two SCSI bus connectors and
power connector on the back of the tabletop drive.
SCSI Cables
The SCSI bus cable leading f rom the host adapter can be connected to either of the
connectors. If the tape unit is the last device on the bus, then a terminator s hould be
installed on the open connector . If the bus continues from the tape dri ve to another
SCSI device, then install a SCSI bus cable between the open connector and the
next device on the bus.
1. Prior to connecting the SDLT drive to the host computer, make sure the drive
and computer are turned OFF.
2. If you are connecting several devices to the SCSI bus, connect only the drive
to the host computer at this time. Conf irm that the host compute r and drive are
communicating correctly before adding additional devices.
3. The SCSI bus must be terminated at each end. Depending on the terminator
supplied (Quantum 68-pin LVD/single-ended terminator with part number 1260308-01 or Quantum 68-pin HVD differential terminator with part number
12-41769-01); snap the wire cable clamps into place or tighten the screws to
secure the terminator.
If the SDLT drive is the only device connected to the SCSI bus, attach the
SCSI terminator to one of the connectors on the back of the drive.
4-22 March 20 04 81-850 02 - 01
SDLT 220 and SDLT 320 Product Manual CHAPTER 4: Installing Your Tape Drive
If the SDLT drive is one of several devices connected to the SCSI bus,
and it is the last device connected to the SCSI bus, attach the SCSI
terminator to one of the connectors on the back of the drive.
4. Align the appropriate SCSI cable to its matching connector on the drive.
Carefully connect the cable, to avoid bending or damaging the connector pins.
Check the SCSI cable and termination connections and ensure that they are
attached correctly and seated firmly.
5. Snap the wire cable clamps into place to secure the cables.
AC Power Cable
An AC power cord is supplied with each tabletop unit. Carefully inspect the power
cord and ensure that the cord is the appropriate cord for your country or region
based on the criteria below.
W
ARNING: Do not attempt to modify or use a tabletop 100–115
VAC power cord for 220–240 VAC input power.
Modifying the power cord in any way can cause
personal injury and severe equipment damage.
The AC power cord used with the tabletop unit must meet the following criteria:
• The power cord should be a minimum of 18/3 AWG, 60°C, type SJT or SVT.
• UL and CSA certified cordage rated for use at 250 VAC with a current rating
that is at least 125% of the current rating of the product.
• The AC plug must be terminated in a grounding-type male plug designed for
use in your country or region. It must also have marks showing certification
by an agency acceptable in your country or region.
• The tabletop unit cord connector must be an IEC type CEE-22 female
connector.
• The cord must be no longer than 4.5 meters (14.5 feet).
• The cord must be FCC compliant with emissions specifications.
Figure 4-8 on page 4-24 shows the AC power cord plug-end types for 115 VAC
and 220/240 VAC usage.

5.1 Power On Self Test
When power is applied to the tape system, the system performs a Power On Self
Test (POST). POST completes in approximately ten seconds. While POST is
running, the tape system responds BUSY to SCSI commands. The tape system
also responds to various SCSI messages during POST.
During this time, if a host tries to negotiate Synchronous or Wide transfers, the
tape system will negotiate to Asynchronous or Narrow . It may take longer than the
duration of POST for the drive to become ready.
Table 5-1 . Indicator Pattern During POST
Stage What Can Be Observed
1 The LEDs light in a progressing pattern from left to right.
2 The red and yellow LEDs are extinguished and the green L ED
flashes until PO S T completes.
3 If POST fails, th e green and yellow LED will illuminate
steadily and the red LED will blink.

5.2 Performing a Trial Back-up
Complete the following steps to perform a trial back-up and verify the tape drive
has been correctly installed:
• Insert a cartridge. Push the cartridge completely into the system. The tape will
load automatically.
• Choose a sample file set from the host computer.
• Perform a back-up and then restore the file set. The system has been correctly
installed if the back-up is completely restored without any errors. If you
experience errors, doublecheck the drive’ s configuration and setup, using the
ideas provided in “Troubleshooting” on page 5-17. After you have exhausted
all troubleshooting alternatives, contact your service representative.
• Press the Eject button to unload the cartridge. If you are unsure which button
is the Eject button, refer to Figure 5-1 on page 5-11.

5.3 Updating the Firmware
When you need to update the firmware in a drive, you can do it either of t wo ways:
• Build a firmware image tape; this tape can be used in either a manual
firmware update or in a Library setting.
• Update the firmware over the SCSI bus.
Both of these approaches are described briefly in the following subsections.
NOTE: For more information about the suite of diagnostics tools
provided by Quantum, refer to Quantum’s web site,
http://www.quantum.com. Follow the path Support =>
Drivers and Software .
5.3.1 U pda te the Fir m w ar e U sing t h e SCSI Bus
SDLT Update is a tool that allows you to update a drive’s firmware (using the
SCSI bus), or to create a code update (CUP/FUP) tape for an SDL T drive.
SDLT Update is available on Quantum’s web site, http://www.quantum.com.
Follow the path Support =>Drivers and Software and download the SDLT
Update package. For detailed instructions to use while updating the firmware,
refer to that tool’s built-in online help.

SDLT 220 and SDLT 320 Product Manual CHAPTER 5: Using Your Tape Drive
5.3.2 Making a FUP/CUP Tape
SDLT Update is a tool that allows you to update a drive’s firmware (using the
SCSI bus), or to create a code update (CUP/FUP) tape for an SDL T drive.
SDLT Update is available on Quantum’s web site, http://www.quantum.com.
Follow the path Support =>Drivers and Software and download the SDLT
Update package. For detailed instructions about how to make the tape, refer to that
tool’s built-in online help.
5.3.3 U sing a C UP/FUP Tape
Follow these steps to use a CUP/FUP tape that was previously created by you or
someone else:
1. Verify that the drive is turned on (power is applied), and the Green (Drive
Status) LED is on, but not blinking.
2. Verify that the drive’s tape opening is empty . (In other words, if any other tape
cartridge is in the drive, unload and eject it.)
3. Press and hold the Eject button for six seconds; after six seconds, the Amber
(Write Protect) LE D will begin to blink.
4. Release the Eject button, then quickly press and release the Eject button again.
At this point, the Amber and Green LEDs start blinking synchronously in a
regular, rhythmic pattern. The drive is now in Firmware Upgrade mode.
You now have a “window” of one minute to insert the tape cartridge. If you do
not insert a CUP/FUP tape and the one minute time window expires, both
LEDs will stop blinking, although the Green LED will remain on (steadily
illuminated). The drive is now out of Firmware Upgrade mode and can be
used in a normal manner (once you insert a data tape cartridge). To put the
drive back in Firmware Upgrade mode, repeat steps 2, 3, and 4 above.
5. Insert the CUP/FUP tape that was previously created.
6. After you insert the tape, the Amber LED and the Green LED will change
their pattern, and start blinking in an alternating pattern. The drive is now
performing the Firmware Upgrade.
81-85002-01 March 2004 5-5
CHAPTER 5: U si ng Your Tape D ri ve SDLT 220 and SDLT 320 Prod uc t Ma nual
NOTE: The Firmware Upgrade will fail the microcode update
process if the firmware personalities do not match; this
will be noted in the history log, along with the reason for
the failure.
7. Wait several minutes for the update process to complete. The Amber and
Green LEDs will blink the entire time that memory is being updated.
8. When the update is complete, the drive resets itself and goes through POST.
The tape is rewound, unloaded, and ejected from the drive. SCSI status will
indicate that microcode has been updated (06h, 3F, 01).
NOTE: If the drive is mounted in a tape automation library, the
tape is not automatically ejected, but it is rewound to
BOT and unbuckled in preparation for unloading.
5.3.4 Troubleshooting th e Firmwa re (Code ) Up dat e
Try these remedial actions if the drive’s firmware (code) update fails:
• Updating the same revision
If a Code Update is requested and the code revision being updated is the same
as the code revision already in the unit, the system updates controller code but
not servo-specific code. The steps for this type of update are the same as for a
normal update.
• Updating fails, which causes the drive to be reset; the problem can result from
any of the following circumstances:
Cartridge contains incompatible update image.
Cartridge does not contain an update image.
No cartridge in the drive.

5.4 Cleaning the Tape Mechanism
This section discusses the SDL T cleaning tape, maintenance considerations, and
important compatibility issues you need to be aware of.
NOTE: Use the SDLT cleaning tape if cleaning is indicated
through your backup software or when the yellow alert
light is ON. Do not clean the drive unless the drive
specifically indicates cleani ng is necess ar y.
5.4.1 O cca si onal Cleaning of Tape Head
SDLT drives may not require preventative cleaning, because of improvements in
the head design. The frequency of cleaning is dictated, to a large degree, by the
amount of ambient pollution and particulates in the environment. For details , refer
to “Particulate Contamination Limits” on page 3-15.
Do not clean your drive unless cleaning is indicated. Your backup software or the
yellow alert light (LED) notify you if you need to clean the drive.
CAUTION: Never use a DLT cleaning tape in an SDL T drive; DLT
cleaning tapes are incompatible wit h the SDLT heads.
81-85002-01 March 2004 5-7
CHAPTER 5: U si ng Your Tape D ri ve SDLT 220 and SDLT 320 Prod uc t Ma nual
5.4.2 When to Use the Cleaning Tape
SDLT uses a built-in tape cleaning algorithm in conjunction with a cleaning tape.
The SDLT cleaning tape is housed in a plastic case, and is light gray in color.
A yellow LED (light) located on the front bezel of the tape drive indicates when
cleaning is needed; the location of this LED (and other front bezel LEDs) is shown
in Figure 5-1 on page 5-11.
NOTE: The tape cleaning algorithm is not used for the backward
read compatible (BRC) head; this head style does not need
cleaning.
5.4.3 Life Expectancy o f the C leaning Tape
Each SDLT cleaning tape is good for 20 uses. Use one of the Quantum-supplied
labels that come with the tape to keep track of the number of uses.
5.4.4 Compatibility of the Cleaning Tape
The SDLT cleaning tape is intended for use in SDLT drives, autoloaders and
libraries only. Alternatively stated, the cleaning t ape only cleans the SDLT MRC
heads.
AUTION: Never use a DLT cleaning tape in an SDL T drive; DLT
C
cleaning tapes are incompatible wit h the SDLT heads.

Follow these steps to load an SDLT cleaning tape into an SDLT tabletop drive:
1. Insert the cleaning cartridge, with the Front Slide Label Slot facing outward,
into the drive until the drive engages with the cartridge and begins to take up
the cleaning media. The green Drive Status LED blinks and the cleaning cycle
begins automatically.
2. When the cleaning cycle completes, the cartridge automatically ejects from
the drive and the yellow alert LED turns off.
NOTE: On the last cleaning, the cleaning cartridge wi ll not eject.
Use the Eject button on the front of the drive to eject the
expired cleaning cartridge and dispose of the cartridge.
3. Remove the cartridge, place it back into its plastic case, and mark the label
after each cleaning.

5.6 Density Selection
This section describes the SDLT drive’s density select features. Density selection
is a feature that enables you to specify that your SDLT 320 tape drive write data
cartridges that are backward compatible with your SDL T 220 tape drives. For
example, if you load a new Super DLTtape I data cartridge in the tape drive and
use a commercially available backup utility , your SDLT 320 tape drive writes data
in SDLT 320 format. However, by using Density Select to specify SDLT 220
format, the SDLT 320 tape drive reads and writes data in that format, enabling
SDLT 220 tape drives to read the data cartridge.
5.6.1 Selecting Tape Density
Selecting Density via the Host over the SCSI Bus
1. Use the SCSI MODE SELECT command to indicate the desired density.
NOTE: Any of the following events cause the drive to reve rt to its
default density: loading a new data cartridge, power on
reset, bus reset, and bus device reset.
2. Write data to the tape from BOT.
When writing from BOT , tape density may be changed by using the operating
system to issue a density designation, or override. In this case, the amber Drive
Density LED on the tape drive’s front panel behaves as shown in Table 5-4 on
page 5-16, indicating an automatic or host density selection.
NOTE: On all READ and all WRITE APPEND operations, the
data density that already exists on the tape cartridge
remains the density.
81-85002-01 March 2004 5-13
CHAPTER 5: U si ng Your Tape D ri ve SDLT 220 and SDLT 320 Prod uc t Ma nual
CAUTION: If a prerecorded tape is reused and a WRITE from the beginning of tape
(BOT) executes (No Append Write), any data already recorded on the tape
will be lost.
SDLT 220 and S DLT 320 C ompatibility Issues
For more information about what happens when a 320-formatted cartridge is
inserted into a SDLT 220 drive, refer to Section A.7, “Overwriting 320-Formatted
Super DLTtape I Data Cartridges” on page A-11.
Forcing Tape Density with MODE SELECT Parameters
The Default Density Override parameter on the Vendor Specific Configuration
Page (25h) can be used to override the default density for the tape until a new data
cartridge is loaded.
NOTE: For more specific information about tape density codes,
refer to the SCSI command descriptions for MODE
SELECT and MODE SENSE. You can find these in a
separate document published by Quantum, SDLT 220 and
SDLT 320 SCSI Interface Guide, 81-85001-01.

This section describes the behavior of the left-most LED on the Quantum SDLT
320 data tape drive. This amber-colored LED is now defined as the Drive Density
indicator (formerly Write Protect).
On the SDLT 320 drive only (not SDLT 220), the amber LED is illuminated when
the density has been set to 220 mode or when an inserted cartridge is detected by
the drive as being formatted in 220 mode. This LED is not illuminated when the
drive is operating in 320 mode, which is the default. See Table 5-4 for specific
scenarios.
Refer to T able 5-4 to help you interpret the behavior of the Drive Density Indicator
LED. Also, please note that the Drive Density LED is not illuminated while the

5.7 Troubleshooting
The following subsections provide troubleshooting information that might be
helpful should the system fail its Power-On Self Text (POST).
Refer to the tape cartridge appendices in this manual (Appendix A, “Super
DLTtape I Data Cartridge” and Appendix B, “DLTtape IV Data Cartridge” ) fo r
complete visual inspection instructions for Super DLTtape I and DL Ttape data
cartridges.
The web site http://www.quantum.com/sdlt includes much valuable information
about SDLT systems.
5.7.1 POST Troubleshooting
Table 5-5 provides troubleshooting tips that you will find useful in the event that
your tape system fails its POST.
If, after attempting the recommended actions listed in the table, the problem still
exists or recurs, a hardware failure may be the cause. Contact your service
representative.

5.7.2 O ver Temperatur e C ondition
An Overtemp condition is defined to be when the calculated Tape Path Temp =
52 degrees C. When this condition is detected, the tape is rewound, unloaded, and
ejected from the drive. (As long as the drive is not mounted in a tape automation
library, the tape is ejected.) SCSI status will indicate the drive is in the over
temperature condition.
NOTE: If the drive is mounted in a tape automation library, the
tape is not automatically ejected; for details , refe r to a
separate document, SDLT 220 and SDLT 320 Design and
Integration Guide, 81-81148-01.

CHAPTER 6 SCSI Description
This chapter covers the following topics:
• “SCSI Overview” introduces the SCSI specification.
• “SCSI-2 Commands” lists the SCSI-2 commands implemente d by
SDLT 220/320.
• “SCSI-3 Commands” lists the SCSI-3 commands implemente d by
SDLT 220/320.
• “Parity” defines the meaning of data parity checking.
• “Signal States” defines the meaning of SCSI signal values and SCSI IDs.
• “SCSI Signals” defines SCSI signals and provides bus timing values.
6.1 SCSI Overview
The Small Computer System Interface (SCSI) is a specification for a peripheral
bus and command set that is an ANSI standard. The standard defines an I/O wide
SCSI bus that supports up to 16 devices (15 SCSI devices and one host adapter).
ANSI defines three primary objectives for SCSI-2:
1. T o provide host computers with device-independence within a class of
devices.
2. To be backward-compatible with SCSI-1 devices that support bus parity and
that meet conformance level 2 of SCSI-1.
3. To move device-dependent intelligence to the SCSI-2 devices.

CHAPTER 6: SCSI Description SDLT 220 and SDLT 320 Product Manual
Important features of SCSI-2 implementation include the following:
• Efficient peer-to-peer I/O bus with up to 15 devices
• Asynchronous transfer rates that depend only on device implementation and
cable length
• Logical addressing for all data blocks (rather than physical addressing)
• Multiple initiators and multiple targets
• Distributed arbitration (bus contention logic)
• Command set enhancement.
For more details about specific SCSI commands or messages, refer to a separate
document published by Quantum, SDLT 220 and 320 SCSI Interface Guide,
