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 Communi cations 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.
