The Front Panel includes the User Control Panel with LCD display and Control
Buttons, LED indicators, and the Front Door Panel.
Control Panel
The control panel presents:
• A backlit green LCD matrix display
• Four control buttons
• Two LED indicators (green and red/amber).
4 Tandberg SLR Autoloader Service and Repair Manual
LCD Display
In various modes of operation, the display panel screens can show you:
• Drive and loader status
• Menu choices, and
• Error messages.
Through most of its operation, the backlit screen displays four 20-character lines of
information. This manual refers to the four text lines of the screen as line 1 through
line 4, moving from top to bottom. You can scroll some screens to greatly expand
the amount of available information. A pointer symbol (θ) indicates additional
options.
Control Buttons
The control buttons let you perform manual tape handling operations, configuration,
and diagnostics:
• The Load button (top left) lets you load tapes from the magazine to the drive.
• The Unload button (lower left) lets you unload tapes from the drive and
return them to the magazine.
• The Open Door button (lower right) releases the door latch after the
completion of any in-process action and when the loader is idle.
• The Menu button (top right) lets you enter menu mode where you can select
configuration options and perform unit diagnostics.
When you enter menu mode, the buttons are re-identified on the display screen to
indicate the different functions they perform under alternate menu levels.
LED Indicators
The green Ready indicator illuminates when the unit is powered up and standing by
to receive instructions. When you start a load, unload, or open door action, the
Ready indicator goes out. The indicator remains illuminated as you enter menu mode
and as you then access the system data. The loader will not remain in a ready state if
you access any other area of the menu mode, and the indicator will then go out.
The red or amber Fault indicator illuminates when the unit experiences a mechanical
fault in the drive or loader robotics. If such a fault occurs, refer to the Error Code
tables in Chapter 6 – Troubleshooting. If that does not clear up the fault, contact
your Technical Support Representative.

Tandberg Data Chapter 1 - Introduction
Front Panel Door
The door is opened by a control panel button, with the door latch being released by
the Autoloader robotic mechanism. In order to operate the front door AC power
must be applied. The hinged door swings open to the left, permitting access to the
tape cartridge magazine.
While the door usually remains locked during normal operations, you can open it,
even with a tape in the drive. If you try to open the door with a tape in the drive, the
unit displays a warning message. You can unlock the door or cancel the operation.
6 Tandberg SLR Autoloader Service and Repair Manual
Tape Cartridge Magazine
The 8-cartridge magazine is accessible through the front panel door. The rugged
polymer magazine fits into an alignment guide, which assures precise cartridge
positioning with respect to the loader robotics.
The only correct insertion orientation for the magazine is shown in the photographic
sequence on the next page.
As the magazine moves into its loader compartment, it should move inward until it
snaps into place. (The two chassis metal detents snap into the magazine slots in its
top surface). The magazine locks into position when you close the front door panel.
Note: The SLR Autoloader is shipped with a soft vinyl dust cover for use when the
magazine is not installed in the loader unit. The cover is contained in the

Bar Code Reader
An integrated bar code reader is installed as standard equipment in the SLR
Autoloader. It is an integral part of the robot shuttle assembly and moves with it.
At power up, the loader automatically pulls each cartridge into the robot shuttle to
scan the bar code, and replaces it in the magazine. If the magazine is full, then it
takes approximately 150 seconds (in addition to the normal inventory / calibration
time) to scan all cartridges, since one cartridge can be scanned in 9 seconds, then
returned in equal time to its slot.
Usually hidden by the metal chassis, the bar code reader is located at the leading
edge of the shuttle slot as shown in the following illustration:
Tandberg SLR Autoloader Service and Repair Manual 9
Tandberg Data Chapter 1 - Introduction
Bar Code Label
The bar code label is encoded with a Code 3 of 9 standard bar code format.
The label for all cartridges consists of six alphanumeric characters: three alpha
characters and three numeric characters. The cleaning cartridge uses CLN as the
alpha characters. For example:
Data cartridge ABC000
DEF123
Cleaning cartridge CLN000
CLN123
Note: You should enable the Enable Check Char option for the most reliable bar
code reader function.
Position the label centrally on the cartridge spine with the six alphanumeric
characters aligned with the cartridge’s base plate.
Ordering Bar Code Labels
You should order additional bar code labels directly from Tandberg Data. Tandberg
bar code labels are made of a mirror-like substrate with special reflectivity, bar
widths, and other characteristics.
Caution: Do not substitute any other bar code labels. They will be unreadable.
See Appendix B – Spares/Accessories for part number information.
10 Tandberg SLR Autoloader Service and Repair Manual
Calibrating the Bar Code Reader
To calibrate the bar code reader, do the following:
1. Insert a cartridge in Slot 2 of the SLR Autoloader. Make sure the cartridge has a
bar code label that is:
• Tandberg approved for SLR Autoloader
• Clean
• Properly positioned on the cartridge.
2. Power up the Autoloader.
3. Press and hold down the
Menu button while you press and release the Load
button.
4. Continue holding down the

back and forth across the bar code reader sensor.
It displays the upper and lower values as it progresses through the calibration
and then displays one of the following:
• If the calibration passes
PASSED
• If the calibration fails or is aborted ABORTED
• If there is no cartridge in Slot 2 NO CARTRIDGE IN SLOT 2
6. If there is no cartridge in Slot 2, exit the DIAGNOSTICS MENU, open the door,
place a cartridge in Slot 2, reinsert the magazine and start the procedure again
from Step 3.
Tandberg SLR Autoloader Service and Repair Manual 11
Tandberg Data Chapter 1 - Introduction
Rear Panel
The rear panel includes eight mechanical devices that relate to bus communication,
firmware upgrading and troubleshooting, device cooling, and line power. Bus
communication between the SCSI Bus connector and the Host adapter occurs
through SCSI Bus connectors (see SCSI In and SCSI Out). The Diagnostic Port
provides sequence information, diagnostic test results and firmware updates. Line
power is supplied and monitored after its circuit is opened by the Power Input Plug,
Power Supply Fuse (in its holder) and the Power Switch. The Product Information
Label includes Model and Serial numbers and cautionary information.
Note: The two empty screw holes on the bottom of the panel are intended for use
only if you mount the unit in a rack. If you have ordered the rack mount conversion
kit, the appropriate fasteners used in this location are provided.
Integrated Cooling Fan
The rear panel contains a single forced-air cooling fan, which draws air inward
through the front of the unit and expels it out the back. The fan prevents overheating
of the drive and robotics electronics, the motors, and the power supply.
Since there is no air filter to clean on a regular basis, you should inspect
occasionally for lint or dust buildup and vacuum the area if necessary.
12 Tandberg SLR Autoloader Service and Repair Manual
Power Switch
The power switch is located on the upper right corner of the rear panel. It is a twoposition rocker switch that controls the supply of AC power to the unit:
• To turn the power ON, depress the switch on the 1 side. The LCD display
illuminates.
• To turn the power OFF, depress the switch on the 0 side.
Power Supply
The auto ranging power supply will adjust to the operating voltage range supplied
through the power cable. The nominal range is 110–240 VAC. The power supply is
capable of operating at 50 or 60 Hz without modification. AC power from a properly
grounded outlet is supplied through a line power cable shipped with the SLR
Autoloader.
For more information on line power cables, see the Power Cable section of Chapter
2 – Installation.
Power Supply Fuse Holder
The power supply fuse holder is located below the power switch as indicated by the
outline diagram on its surface. The procedure for accessing power fuse (and its
spare) is shown below.
Note: Before replacing the fuse, set the Main power switch to OFF and remove the
power cord.
Tandberg SLR Autoloader Service and Repair Manual 13
Tandberg Data Chapter 1 - Introduction
SCSI Interface Connectors
The SCSI Interface connectors link the internal SCSI bus devices (SCSI drive and
robotic controllers) to the external host adapter. The bi-directional SCSI bus
transfers the SCSI commands and data. To provide this function, there are two 68pin, high density, shielded D-type SCSI Connectors which connect to shielded SCSI
Type P cables. The pair of connectors allows for daisy chaining more than one SLR
Autoloader to a host adapter or other SCSI-compatible device. When only one SCSI
connector is used, the second connector must be terminated using the supplied
LVD/SE dual mode terminator.
Ethernet Port
The Ethernet port is reserved for future use.
Diagnostic Port
The Diagnostic port (RS-232) is used to upload fault analysis data by the service
technician after a fault condition occurs. It is also used to update the firmware in the
controller card’s flash memory.
Embedded Diagnostics
• The SLR Autoloader includes three levels of diagnostics:
• The Power-On Self Test (POST) — Performs several verification and
memory tests when you power on the unit.
• User Diagnostics — Lets you change setup options. Select from front panel.
• Tech Support Diagnostics — Used by Technical Support Engineers to
diagnose faults and service the unit.

Tandberg SLR Autoloader Service and Repair Manual 18
Tandberg Data Chapter 2 - Installation
Mounting Tabletop Units
Tabletop units require no mechanical assembly. Place the unit on a desk, table,
server top, or other stable, horizontal surface with at least 2-inch (5 cm) clearance
behind it to allow free flow of cooling air from the fan.
CAUTION: Make sure the Autoloader stays in a horizontal position while
operating. Do not operate it on its side.
Mounting Rack Units
The compact size of the SLR Autoloader permits the mounting of up to two units in
a single shelf of a standard 19” rack. Both units attach to a rack chassis. The units
are secured to the rack chassis by rear brackets and fastened in place by two
machine screws. The chassis and both units fit within a 4U rack height.
Note: Before mounting the SLR Autoloader(s), you must order a separate hardware
kit for converting the unit(s) from a tabletop to a rack mounted one.
Rackmount Installation Process
1. Add the rack chassis to the rack frame.
2. Fasten one or two SLR Autoloader chassis to the installed rack chassis.
Tandberg SLR Autoloader Service and Repair Manual 19

1. Attach the left support bracket to the left rear rail surface side using two 1032x1/2” screws and two 10-32 nut plates.
2. Attach the right support bracket to the right rear rail surface side using two 1032x1/2 screws and two 10-32 nut plates.
3. Attach the front chassis to the inside surface of the front rack rail using four 1032x1/2 screws (two for each side).
4. Attach the left and right bracket(s) to the outside rear chassis surface using four
10-32x1/2 screws and four10-32 hex nuts (two screws and two hex nuts on each
side).
5. Attach left endcap to outside surface of left front rail by snapping a ball stud into
a retaining clip located on the front chassis mounting flange.
6. Repeat Step 5 for the right endcap.
The rack chassis is now ready to mount the SLR Autoloader unit(s).
Installation of SLR Autoloader(s)
To install a single SLR Autoloader:
1. Attach to either the left or right side: the front filler panel to the chassis using
two screws (M3 x 6mm).
2. Prepare the unit before installation:
• Remove the four screws and four rubber feet from the bottom panel of the
unit
• Remove the SLR Autoloader chassis cover by sliding it rearward.
3. Insert the prepared SLR Autoloader unit into the rack chassis until it is stopped
by the rear-mounting bracket.
4. Secure the unit to this bracket using two screws (M3 x 8 mm).
To install two SLR Autoloaders:
1. Prepare both units as described in Step 2 for installing a single unit.
2. Insert both units into the chassis until they are stopped by the rear mounting
brackets.
3. Secure each unit to its mounting bracket using two screws (M3 x 8mm).
Tandberg SLR Autoloader Service and Repair Manual 20
Tandberg Data Chapter 2 - Installation
Cabling and Interface Connections
Before the SLR Autoloader can be powered up or communicate with the host device
or user applications, the following connections must be made (see the diagram of the
rear panel’s connectors on the next page):
• AC line power
• Select and connect the proper line power cable (from the pair of power
cables sent in the Accessory Kit shipped with the SLR Autoloader) between
the Power Input Plug (see the illustration below) and your line power outlet.
• SCSI bus connection to the host (68 pin LVD or SE).
• Connect the SCSI Cable between the SCSI Out connector of the Host
Adapter to the SCSI In connector of the SLR Autoloader. If the SLR
Autoloader is not being daisy-chained to another device, then connect the
supplied LVD/SE Terminator to the SCSI Out connector.
Power Cable
The power cable is a standard grounding AC cable, which plugs a 3-wire connector
into the rear panel and the other end has a country-specific connector plug that fits
into a reliably grounded AC outlet.
Tandberg SLR Autoloader Service and Repair Manual 21
There are two types of power cables supplied with the SLR Autoloader. They differ
in their cable connectors and length. Each cable has a different terminal ending for
connecting to local line power. The cable length of the USA version is 6.5 feet (2.0
m); the European one is 2.5 m.
To maintain product safety compliance, select the power cord with a suitable
electrical rating that is approved for the country where the product is used. In the
USA, use a UL listed cord; in Canada, a CSA certified cord; and in Europe, use a
Harmonized cord marked <HAR> or a nationally certified cord.
Note: After connecting the SLR Autoloader to your AC source, it is a good practice
to do a test power up of the unit before connecting to the host computer. This will
verify proper initialization and electrical behavior and isolate unexpected conditions
to the host interface. The affirmation that the system is operating properly is the
appearance of the cartridge map on the display panel, along with the green Ready
LED being lit. (See the beginning of Chapter 3 – Operation for an example of a
cartridge map on the display panel.) Power down the unit before connecting to the
host.
Interfaces
The SLR Autoloader is supplied with both single-ended Fast/Wide and LVD Ultra 2
SCSI interfaces. The unit configures automatically to either interface.
The Fast/Wide SCSI interface uses high-density 68-pin connectors. Fast/Wide SCSI
cables and terminators are secured to the connectors by jackscrews.
The drive and the robotics are separate SCSI devices. They require unique SCSI
address because they are daisy-chained on the same bus. The SCSI addresses of the
robotics and drive may be set from the control panel.
In order to connect the unit to a host computer system, the host system must have a
compatible SCSI controller and the appropriate driver software. Call your Technical
Support representative if you have any questions about installing for specific host
systems.
Tandberg SLR Autoloader Service and Repair Manual 22
Tandberg Data Chapter 2 - Installation
Interface Cable Specifications
The SLR Autoloader is a high-performance system. To avoid degradation of
performance, any additional or replacement cables you use should likewise be of the
highest quality. The detailed requirements for SCSI cables are set forth in ANSI
X3.131-1994. All SCSI cables used with the SLR Autoloader should meet the
following requirements:
• Shielded or double-shielded, as required to meet EMI specifications
• Nominal characteristic impedance is 90 single-ended and 132 ohms
differential

using good quality shielded cables. The use of unshielded cables, poor quality
cables or other variances from good practice may result in non-compliance with
national and international rules and degraded performance.
Interface Cable and Terminator Installation
An LVD/SE terminator is supplied with your unit, packaged in the accessory kit
bag.
This terminator must be installed onto the device used at either end of a SCSI bus,
such as the first or last device along a daisy-chain, or as a single SCSI peripheral.
Usually, the host computer’s SCSI interface is at one end of the bus and terminated,
so the question is whether the SLR Autoloader or another device is the last device
on the bus.
On the rear panel of the unit, the incoming SCSI bus is connected to the left SCSI
connector and the terminator or the outgoing SCSI bus is connected to the right
SCSI connector (see the illustration on the next page).
To properly cable the drive, do the following:
1. Make sure the unit and the host computer are powered down.
2. Make sure that your host system has appropriate SCSI interface card or cards
and software drivers installed. The interface card should use Fast/Wide or
Ultra/Wide SCSI, single-ended or low voltage differential (LVD). All models of
the SLR Autoloader are equipped with a LVD/SE Wide SCSI interface. Be sure
to use the same type of SCSI hardware consistently throughout your
configuration.
3. Use only the SCSI terminator supplied with the SLR Autoloader. It should be
one of two available models — either with or without an LED indicator light.

4. If the SLR Autoloader is the only SCSI device you want to connect to the
interface card, connect the cable from the interface card to the incoming SCSI
connector, attach the terminator to the outgoing SCSI connector, then skip to
step 6.
5. If you have two or more additional SCSI devices to connect to the interface card,
your SLR Autoloader must be connected in daisy-chain fashion. That means
that the cable from the interface card must be connected to the incoming SCSI
connector of the first SCSI device, the cable from the outgoing connector of the
first device must be connected to the incoming connector of the second SCSI
device, and so on. You can connect them in any order. The terminator must be
attached to the outgoing SCSI connector of the last device in the chain.
6. Make sure that each cable you use meets the specifications listed earlier in this
chapter.
