SPIRENT

SPT-N4U COMPACT CHASSIS

The Spirent SPT-N4U compact chassis is the smallest chassis form factor that supports
Spirent’s new 10GbE, 40GbE and 100GbE test modules. By optimizing the packaging and
through the use of the latest technology, the SPT-N4U is designed to lower the cost of testing
the devices and networks powering the always-on data network.

The SPT-N4U supports Spirent’s latest high-density test modules
in a smaller chassis form-factor that incorporates innovative
time- and money-saving capabilities such as: Built-in touchscreen
administration, intelligent power and fan control, fast booting
and system firmware upgrades.

With its efficient architecture, the SPT-N4U supports a variety of
environments where the testing requires equipment to be
relocated from time-to-time. It also supports multi-user functional
testing and chassis chaining where higher density is required but
a mainframe N11U is not available. The N4U is fully interoperable
with the N11U and accepts the same test modules with
no modifications.
