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.

Why Buy From Black Box? Exceptional
Value. Exceptional Tech Support. Period.
