Thermal Specifications
Notes:
1.
Intel
®
Xeon
®
processor LC3518 Thermal Profile is representative of a volumetrically constrained platform.
See
for discrete points that constitute the thermal profile.
2.
Implementation of Intel
®
Xeon
®
processor LC3518 nominal and short-term thermal profiles should result
in virtually no TCC activation. Furthermore, utilization of thermal solutions that do not meet this Thermal
Profile will result in increased probability of TCC activation and may incur measurable performance loss.
3.
The Nominal Thermal Profile must be used for all normal operating conditions, or for products that do not
require NEBS Level 3 compliance.
4.
The Short-Term Thermal Profile may only be used for short-term excursions to higher ambient operating
temperatures, not to exceed 96 hours per instance, 360 hours per year, and a maximum of 15 instances
per year, as compliant with NEBS Level 3. Operation at the Short-Term Thermal Profile for durations
exceeding 360 hours per year violate the processor thermal specifications and may result in permanent
damage to the processor.
