SmartFan Fusion provides more telecom cooling power (9 Amps), more DC fan speed control and alarm capability (up to 9) than any previous CRI product. In addition, the Fusion fan speed control offers the features & flexibility of its telecom cooling predecessor, the SmartFan Multi-SR, plus ATCA compliance for managed or intelligent FRU telecom cooling systems. In order to fully meet the telecommunications industry's first open standard for carrier-grade systems, the Fusion fan speed control will communicate with telecom cooling shelf management modules via dual IPMBs as specified by AdvancedTCA PICMG 3.0.
|
The fan speed control will provide FRU information, individual fan status and temperature readings. The Fusion accepts fan speed control commands and regulates fan speed using a buck regulator control circuit. The Fusion can also be configured for fan speed control based on temperature, I2C commands (single or dual) or analog control signal (PWM, 5.0 VDC). Configuration of the Fusion is settable via I2C interface or options can be set at the factory to your telecom cooling specifications
