Understanding Autoloader Features
The autoloader is a SCSI-2 low-voltage Differential (LVD) data storage device that incorporates a Dell PowerVault 122T LTO tape drive and eight tape slots. The autoloader occupies two SCSI target addresses, one for the tape drive and the other for the autoloader robotics. The autoloader uses up to eight LTO Ultirium data cartridges, providing a maximum formatted capacity of 1.6 Terabytes and a sustained data transfer rate as high as 1.8 GB per minute, assuming a 2:1 compression ratio.

The autoloader is compatible with most operating systems and environments that support the SCSI interface, but requires either direct support from the operating system or a compatible backup application to take full advantage of its many features.

Bar Code Reader
Your autoloader may have come equipped with an optional bar code reader. The bar code reader is enclosed in a plastic housing that protrudes out the rear panel of the autoloader, just above the SCSI connectors. The bar code reader automatically scans each cartridge in the carousel upon power up, after a reset, or when a Re-inventory command is issued. (See Creating an Inventory of Cartridges For Instructions.) Beyond that, there is no user interface with the bar code reader via the front panel operator controls or LCD display. The information from each label is stored in memory and available through SCSI to the computer’s operating system or backup application upon request.

If utilizing the bar code reader, you must apply bar code labels to the recessed area on the front of each cartridge. The labels must conform to ANSI/AIM BC1 -1995, Uniform Symbology Specification Code 39. A set of bar code labels will be included with the autoloader. Refer to support.dell.com for information on obtaining additional bar code labels.

SCSI Requirements
The autoloader incorporates a wide SCSI-2, low-voltage Differential (LVD) SCSI bus. The autoloader may be attached to a single-ended (SE) SCSI bus, however this is not recommended as performance will be restricted. Make sure your SCSI host adapter or controller supports these standards. If you connect the autoloader to an SE SCSI bus or if there are SE devices attached to the same SCSI bus, the autoloader's performance is limited to the maximum data transfer speed and maximum cable lengths of the SE bus. The autoloader is NOT compatible with a standard differential (Diff) or high-voltage Differential (HVD) SCSI bus. The autoloader may be attached to a narrow (50-pin) SCSI bus, however this is not recommended, as performance will be restricted. Attaching to a narrow (50-pin) bus will require a customer-supplied 68-pin to 50-pin adapter that terminates the unused 18 pins. a customer-supplied 68-pin to 50-pin adapter that terminates the unused 18 pins. These adapters are sometimes labeled high-byte termination.

Unpacking the Autoloader
Before you begin, clear a desk or table so that you can unpack the autoloader. You also need to select an open 2U computer rack location or choose a desktop location near the server that is to be the host for the autoloader.

NOTICE: If the room in which you are working differs from the temperature in which the autoloader was shipped or stored by 30° F (15° C) or more, let the autoloader acclimate to the surrounding environment for at least 12 hours before opening the shipping carton.

Unpack and inspect the autoloader for shipping damage by doing the following:

Clear a table or desk so that you have room to unpack the autoloader.

Inspect the shipping box for damage. If you notice any damage, report it to the shipping company immediately.

Open the shipping box and remove the accessories package. Set the accessories package aside for now.

Lift the autoloader and padding out of the box and place it on the work surface, top facing up. Do not set the autoloader on either end or sides.

Carefully remove the shipping padding from the left and right sides of the autoloader. Then remove the bag from the autoloader. Save the packing materials in case you need to move or ship the autoloader in the future.

Connecting the SCSI and Power Cables
To connect the SCSI and power cables to the autoloader, follow these steps:

Shut down and turn off the selected server. Turn off all attached accessory devices, such as printers and other SCSI devices. Remove the power cables from the server and all attached accessories.

NOTICE: Failure to remove the power cables from these devices could result in damage to the autoloader.

Attach one end of the SCSI cable (Included In the Accessory Kit) to one of the connectors on the rear panel of the autoloader.

Attach the other end of the SCSI cable to the connector on the SCSI host adapter or to the connector on the previous device on the SCSI bus.

Attaching SCSI and Power Cables

If the supplied SCSI cable does not fit the connector on your SCSI host adapter, you either have an incompatible SCSI host adapter or you need to purchase a cable adapter. Contact your service representative or your SCSI host adapter manufacturer for information.

Attach the terminator to the remaining SCSI connector on the rear panel of the autoloader (If the Autoloader Is the Last or Only Device On the SCSI Bus). Otherwise, attach the cable to the next device on the SCSI bus. Make sure that the last device on the SCSI bus is properly terminated.

Attach the female connector on the power cable to the power connector on the rear panel of the autoloader.

Plug in the power cable to the nearest properly grounded power outlet.

CAUTION: To disconnect all power from the autoloader, remove the power cord from the outlet.

Plug in the host server or workstation and all attached devices.

Turn on the autoloader by setting the power switch on the front panel to the ON position. Turn on any other devices you turned off earlier. Check the LCD display to make sure the autoloader is receiving power. If it is not, check the power connections and your power source.

During the Power-On Self Test (POST), all four LEDs are illuminated briefly, followed by just the Ready/Activity LED flashing. When the initialization sequence is complete, the LCD screen displays the Home screen.

Turn on the server.

Preparing the Host and Verifying the Connection
If necessary, install a SCSI host adapter, software, and compatible driver(s). Refer to the manuals for the host computer and SCSI host adapter for detailed instructions. In addition, follow these general guidelines:

When the host server is powered on, install software, and/or driver(s) that are compatible with the autoloader. (See Installing the Device Drivers For More Information.) Software compatibility information is available at support.dell.com. Most backup software packages require an additional module to communicate with the autoloader robotics.

If the host server is connected to a network, check with the system administrator before turning off power.

Use proper procedures to prevent electrostatic discharge (ESD). Use wrist-grounding straps and anti-static mats when handling internal components.

Make sure that the host server has an open expansion slot.

Make sure that your backup application supports the SCSI host adapter.

Depending on the server configuration, you may need to change the SCSI ID of the autoloader and/or tape drive. (See Changing the SCSI IDs For More Information.)

Ensure the autoloader is properly terminated. If the autoloader is the only SCSI device - other than the SCSI host adapter - on the selected SCSI bus, it must be terminated. Likewise, if the autoloader is physically the last SCSI device on the SCSI bus, it must be terminated. Only the devices physically at the beginning and end of the SCSI bus should be terminated.

Verify the connection between the autoloader and host by:

Making sure that the host server's operating system recognizes the autoloader by going to: Settings -> Control Panel -> SCSI Adapter in Windows NT or Settings -> Control Panel -> System -> Hardware -> Device Manager -> Tape Drive and/or Media Changer in Windows 2000. For more information on verifying the connection of SCSI devices, consult the operating system documentation.
