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 over-temperature induced damage to the power supply.

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.
