The blade provides two independent power inputs according to the AdvancedTCA
Specification. Each input must be equipped with an additional fuse of max. 90A located either
in the shelf where the blade is installed or the power entry module (PEM).
Note: This power requirement is under room temperature (25 o C).
The power consumption has been measured using specific boards in a configuration
considered to represent the worst-case (with RTM-ATCA-737x and SAS HDD, maximum
memory population, ACC-7370 module) and with software simultaneously exercising as
many functions and interfaces as possible. This includes a particular load software provided
by Intel, designed to stress the processors to reach their theoretical maximum power
specification.
Any difference in the system configuration or the software executed by the processors may
affect the actual power dissipation. Depending on the actual operating configuration and
conditions, customers may see slightly higher power dissipation, or it may even be
significantly lower. There is also a dependency on the batch variance of the major
components like the processor and DIMMs used. Hence, Artesyn does not represent or
warrant that measurement results of a specific board provide guaranteed maximum values
for a series of boards.
