Environmental Specifications
Table 2-9 provides the operating and storage temperature ranges required for this module.
Thermal/Cooling Requirements
The Express-CBR is designed to operate at its maximum CPU speeds of 1.06GHz and 2.0GHz and requires
a thermal solution to cool the CPU, PCH, and voltage regulators. ADLINK offers two optional cooling
solutions as well as a heat spreader platform on which to build a cooling solution. (See Table 2-10 for
descriptions of cooling options and Figure 2-7 for stack heights of the optional cooling assemblies.)
