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.

The National Electrical Manufacturers’ Association (NEMA)
issues guidelines and ratings for an enclosure’s level of
protection against contaminants that might come in contact
with its enclosed equipment.
There are many numerical NEMA designations; we’ll
discuss NEMA enclosures relevant to this data sheet: NEMA 3,
NEMA 3R, NEMA 4, NEMA 4X, and NEMA 12.
NEMA 3 enclosures, designed for both indoor and outdoor
use, provide protection against falling dirt, windblown dust,
rain, sleet, and snow, as well as ice formation.
The NEMA 3R rating is identical to NEMA 3 except that it
doesn’t specify protection against windblown dust.
NEMA 4 and 4X enclosures, also designed for indoor
and outdoor use, protect against windblown dust and rain,
splashing and hose-directed water, and ice formation. NEMA
4X goes further than NEMA 4, specifying that the enclosure
will also protect against corrosion caused by the elements.
NEMA 12 enclosures are constructed for indoor use only
and are designed to provide protection against falling dirt,
circulating dust, lint, fibers, and dripping or splashing
noncorrosive liquids. Protection against oil and coolant
seepage is also a prerequisite for NEMA 12 designation.
