uilt for speed, these SCSI-
based CD-ROM Towers
support data-transfer rates of
700 Mbps. In addition, each drive
in the tower holds about 700 MB
of data per CD. You can install up
to nine towers on a single Novell
network for a whopping 63 drives!
Connecting a tower is easy,
too. Use a DiscPort LAN Access
Unit (CDE300A or CDT301A) to
connect each device to your LAN.
Or attach a tower to a standalone
PC directly.
The tower features caddyless
drives, so instant data access is
easy—just drop in a CD.
All models feature a 256-KB
on-board buffer.
T7 Seven CD Tower

to your LAN—without compromising speed,
easy access, or reliability.
Key Features
SCSICD TOWERS
T7 CD-ROM Tower
Choose this device if you need
to access massive amounts of
information. It features special
data-flow management for faster
data-transfer rates.
T5 CD-ROM Tower
Is your department small but
growing? The T5 is the perfect
choice for a network that’s rapidly
adding users. It gives you one
more drive than the T4—plus all
the speed and reliability of the
other models.
T4 CD-ROM Tower
When you don’t need the
storage capabilities of the T7 or T5
but the T2 just isn’t big enough,
choose the T4. It’s perfect for
medium- to larger-size networks.
T2 CD-ROM Tower
If you need a reference tool
for a smaller network, this is the
device for you. Users can search
back and forth between drives,
and it’s just as reliable and speedy
as the T7, T5, and T4.
All the towers meet FCC B
and UL
®
standards. And all also
include quiet cooling fans.

Recognize any of these
situations?
• You wait more than 30
minutes to get through to a
vendor’s tech support.
• The so-called “tech” can’t
help you or gives you the
wrong answer.
• You don’t have a purchase
order number and the tech
refuses to help you.
• It’s 9 p. m. and you need help,
but your vendor’s tech
support line is closed.
According to a survey by Data
Communications magazine, 90%
of network managers surveyed
say that getting the technical
support they need is extremely
important when choosing a
vendor. But even though network
managers pay anywhere from 10
to 20% of their overall purchase
price for a basic service and
support contract, the technical
support and service they receive
falls far short of their
expectations—and certainly isn’t
worth what they paid.
At Black Box, we guarantee
the best value and the best
support. You can even consult our
Technical Support Experts before
you buy if you need help selecting
just the right component for your
application.
Don’t waste time and
money—call Black Box today.
