Introduction

The Spirent SPT-N11U/SPT-N12U mainframe chassis is the foundation for Spirent's new 
series of test modules. By optimizing the packaging and through the use of the latest 
technology, the SPT-N11U/SPT-N12U is designed to lower the cost of testing high-scale 
Internet networks and devices.

With its efficient architecture, the SPT-N11U/SPT-N12U supports a variety of 
environments from multi-user functional testing to multi-chassis switch fabric and core-
router stress testing.

Site Selection

The Spirent SPT-N11U/SPT-N12U is a high-end network testing device that must be 
installed in a dust free and dry environment with adequate airflow, power, and cooling. 

The SPT-N11U/SPT-N12U is designed with front to rear airflow and both ventilation 
locations must remain unobstructed for proper operation. Inadequate cooling or 
airflow can result in an over-temperature situation that will cause an automatic system 
shut-down.

The inlet air temperature must be in the range of 59° to 95° F (15° to 35° C); 20% to 
80% relative humidity

The SPT-N11U/SPT-N12U is designed to be mounted in a Telecom-style 19" 2- or 4-
post open rack.

SPT-N11U chassis occupies 11 rack units, SPT-N12U occupies 12 rack units

The rack must be designed, and adequately secured, to accommodate the fully 
loaded weight of the chassis and any other installed equipment. 

SPT-N11U is approximately 232 lb.

SPT-N12U is approximately 234 lb.

It is not recommended to install the chassis in an enclosure unless it is specifically 
designed to handle the airflow and cooling requirements of the chassis.

Depending on your ordered configuration, a fully loaded chassis requires seven (7) 
115V 15A circuits, or four (4) 230V 15A circuits, with no other connected equipment 
and each with its own breaker. See the section on power requirements (

page 8

) for 

more information.
