Why Buy From Black Box? Exceptional Value.  
Exceptional Tech Support. Period.  
According to a survey by Data Communications  
magazine, 90% of network managers surveyed say  
Recognize any of these situations?  
You w ait more than 30 minutes to get through  
to a vendors tech support.  
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 isnt 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.  
• The so-called “techcant help you or gives you  
the w rong answ er.  
You dont have a purchase order number and the  
tech refuses to help you.  
• Its 9 p. m. and you need help, but your vendors  
tech support line is closed.  
Dont waste time and money—call Black Box today.
