This section describes the LV processors and Embedded reference heatsinks for NEBS
(Network Equipment Building Systems) compliant ATCA (Advanced Telecommunications
Computing Architecture) systems. These LV processors are good for any form factor
that needs to meet NEBS requirements.
E.1
Performance Targets
Table E-1
and
Table E-2
provide boundary conditions and performance targets for 1U
and ATCA heatsinks. These values are used to generate processor thermal
specifications and to provide guidance for heatsink design.
NOTES:
1. Local ambient temperature of the air entering the heatsink.
2. Max target (mean + 3 sigma + offset) for thermal characterization parameter (
Section 5.5.1
).
3. Reference system configuration. In a single wide ATCA blade the 60 W processor should be used in single
