5.7Fan Speed Control
The fan circuitry implements variable speed fan control and fan failure detection.
5.8Environmental Requirements
5.8.1Physical Environment
The power supply is located inside an Intel® system assembly. A system may contain two or three power supplies.
5.8.2Thermal Protection
The power supply incorporates thermal protection that causes a shutdown if air flow through the power supply is insufficient. Thermal protection activates a shutdown if the temperature of any power supply component is more than 85% (° C) of rated temperature. This shutdown takes place prior to
5.9Regulatory Agency Requirements
The power supply must have UL recognition, CSA certification to level 3, Bauart and any NOR- DIC CENELEC certified (such as SEMKO, NEMKO or SETI) markings demonstrating compli- ance. The power supply must also meet FCC Class B, VDE 0871 Level B, and CISPR Class B requirements.
