Chapter 1 - Introduction

Front Panel

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.

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 Accessories Kit box and can be easily slipped over the open end of the magazine.

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

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 Menu button until the READY light turns off. This will take abt. 10 seconds.

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.

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.

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

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

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.

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. See the following illustration.

4.If the SLR Autoloader is the onlySCSIdevice you want to connect to the interface card, connect the cable fromthe 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.
