Chapter 1 Installing the ValueLoader
Understanding ValueLoader Features
ValueLoader LTO-1/LTO-2 Tape Autoloader User Manual 3
The ValueLoader LTO-2 uses up to eight LTO-2 Ultrium cartridges,
providing a maximum formatted capacity of 3.2 TB and a sustained data
transfer rate as high as 3.6 GB per minute, assuming a 2:1 compression
ratio.
The ValueLoader is compatible with most operating systems and
environments that support the SCSI interface, but it requires either direct
support from the operating system or a compatible backup application to
take full advantage of its many features.
Bar Code Reader 1
Your ValueLoader may have come equipped with an optional bar code
reader. The bar code reader is enclosed in a plastic housing that protrudes
out of the back panel of the ValueLoader, 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 on page 33). Beyond that, there
is no user interface with 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 apply bar code labels to the
recessed area on the front of each cartridge. These labels must conform to
ANSI/AIM BC1-1995, Uniform Symbology Specification Code 39. To
obtain additional bar code labels, refer to

SCSI
Requirements
1
The ValueLoader incorporates a wide SCSI-2, LVD SCSI bus. Make sure
your SCSI host adapter or controller supports these standards.
The ValueLoader can be attached to a single-ended (SE) SCSI bus, but this
is not recommended because it restricts performance. If you connect the
ValueLoader to an SE SCSI bus, or if there are SE devices attached to the
same SCSI bus, the ValueLoader’s performance is limited to the
maximum data transfer speed and maximum cable lengths of the SE bus.
The ValueLoader is NOT compatible with a standard differential (Diff) or
high-voltage differential (HVD) SCSI bus. The ValueLoader 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.
