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
provides 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
socket only and the 38 W processor can be used in dual socket.
4. Local Ambient Temperature written 50/65
o
C means 50
o
C under Nominal conditions but 65
o
C is allowed for
Short-Term NEBS excursions.
5. Passive heatsinks with TIM.
6. See
Section 5.1
for standard 1U solutions that do not need to meet NEBS.
