Overview
Description
This section of the document provides a physical description
of the switches, indicators and connectors on the front and
rear panels of the 4000/7000DLT Series. Additional
information describes other requirements (additional
hardware and/or software) needed to utilize the
4000/7000DLT Series.
The 4000/7000DLT Series consists of two models, the
TM
4000 and the DLTTM7000. They are all SCSI-2
DLT
compatible, high performance, streaming tape cartridge data
storage devices designed for storage of near-line and off-line
data. All models use data compression, compaction, and
Digital Linear Tape (DLT) to obtain the capacities shown in
Table 2-1. The 4000/7000DLT Series are equipped with a 2line by 20-character backlit LCD display. The LCD displays
drive status messages, error messages, and drive Power-On
Self-Test (POST) results messages.

The 4000/7000DLT Series are equipped with a 5
factor, half-inch tape drive. The design includes a dualchannel read/write head, Digital Lempel-Ziv (DLZ) highefficiency data compression, and tape mark directory to
maximize data throughput and minimize data access time.
Used for unattended backups or archiving, the 4000/7000DLT
Series allows you to back up a higher data capacity at higher
speed than either 8mm or 4mm DAT-based drives. Table 2-2
lists the maximum compressed mode transfer rates of the two
models:

The removable tape media cartridge allows long-term off-line
and/or off-site data storage. The tape media is rated at up to
500,000 passes and has a shelf life of up to 30 years providing
superior media durability and data reliability.
Table 2-3 on page 2-4 lists the drive models used in the
4000/7000DLT Series. Tape density is selected either from the
drive front panel or the host. The 4000DLT, and 7000DLT
drives can read/write 2.6, 6.0, and 10.0 GB formatted tapes for
100% interchange compatibility with earlier DLT drives.

The 4000/7000DLT Series includes Flash EEPROM
technology that allows easy on-site installation of firmware
updates from tape or from the host.
The 4000/7000DLT Series includes embedded diagnostic
software that tells you when head cleaning is required,
diagnostic results, and drive operating status. The drive has
embedded data logging of errors for failure analysis.
Front Panel Controls and Indicators

Data Cartridge
The data cartridges used in the DTL7000 Series are housed in
4-inch plastic cases and employ 1/2-inch metal particle tape.
Table 2-6 describes and lists the media cartridges that can be
used with the four models.

The Write-Protect
If the switch is moved all the way to the left, the cartridge is
write-protected and the drive cannot write to, or erase data
from, the cartridge. The small orange rectangle will be visible
whenever the cartridge is write-protected. Additionally, an
arrow (beneath the orange rectangle and above the two lines
on the switch), lets you know that data cannot be written to
the cartridge. If the switch is moved all the way to the right,
the cartridge is write-enabled and the drive can write data to,
or erase data from, the cartridge. The orange rectangle will not
be visible whenever the cartridge is write-enabled. On the
right side of the write-protect switch an arrow over one line
indicates that if you slide the switch to the right, data can be
written to the cartridge. Refer to Figure 2-4 on page 2-10.

Caution
Always remove any cartridge from the drive before turning
off host system power. Failure to remove a cartridge can
result in cartridge and drive damage.
When you remove the cartridge from the drive, return the
cartridge to its plastic case to prolong the cartridge life.
Other Requirements
SCSI Host Adapter
If your host system does not have an integrated SCSI
controller, a SCSI host adapter must be used to connect the
host computer with the 7000DLT Series. The host adapter you
choose will depend on your system requirements and your
needs.
2-10 Description
62-0162-01
SCSI Interface Cable
The kind of cable you need will depend on the kind of SCSI
bus connector on your host adapter. The 7000DLT, a fast, wide
SCSI-2 device, uses a 68-pin high density SCSI device
connector.
Application Software
The software you use will depend upon your storage needs
and the system you are using.
Additional Items
• At least one data cartridge. See Table 2-7.
