ment that has a serial console port.

• Include a built-in V.92 modem and a

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.
