Installation Overview

Installing the autoloader consists of the following steps, which are explained in more detail later in this Section:

1. Choose a location for the autoloader (see

2. Unpack and check the autoloader for shipping damage (see

3. Identify the accessories that come with the autoloader (see

4. Install the autoloader in a computer rack or select a table or desktop near the host server. If installing a rack mount unit, refer to your rack Installation

Guide.

5. Shut down, turn off, and remove power from the server and all devices attached to the server (see

6. Attach the SCSI cable to the autoloader and server's SCSI host adapter (see

7. Attach the power cable to the autoloader and plug in the power cable to the nearest power outlet (see

Power the autoloader on to ensure it passes the Power-on Self Test.

8. Set the SCSI ID for the autoloader (see

9. Set up the host and verify the connection (see

Understanding Autoloader Features

The autoloader is a SCSI-2 Low Voltage Differential (LVD) data storage device that incorporates a Dell PV122T DLT VS80 tape drive and eight tape slots. The

autoloader operates as a single SCSI device with two Logical Unit Numbers (LUNs), one for the tape drive (0) and the other for the autoloader robotics (1).

The autoloader uses up to eight DLTtape™IV data cartridges, providing a maximum formatted capacity of 640 Gigabytes and a sustained data transfer rate as

high as 360 MB 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 back

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,

after an import or export, or when a re-inventory command is issued (see

the bar code reader via the front panel operator controls or LCD screen. 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 insert bar code labels into the slide-in slot 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 is included with the autoloader. Refer to

additional bar code labels.

SCSI Requirements

The autoloader incorporates a wide SCSI-2, Low-Voltage Differential (LVD) SCSI bus. Make sure your SCSI host adapter or controller supports these

standards.

The autoloader can be attached to a Single Ended (SE) SCSI bus, but this is not recommended because it restricts performance. 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 can be attached to a narrow (50-pin) SCSI bus, but this is not recommended as performance will be restricted. Attaching to a narrow (50-pin) bus

requires a customer-supplied 68-pin to 50-pin adapter that terminates the unused 18 pins. These adapters are sometimes labeled high-byte termination.
