Fan Control
®
The fans in the Intel
SC5200 Server Chassis are designed for server boards that support fan
®
control, such as the Intel
SHG2 Server Board. The front panel of the chassis has an active
temperature sensor (i.e., Dallas* 1621) connected to the front panel’s bus. Based on the inlet
temperature measured, the server board’s firmware will adjust the fan voltage. This will maintain
proper system cooling of all components and peripherals, while minimizing the acoustic noise level.
A fan sensor will be re-armed by the firmware if it was read as stopped (0 RPM) for one polling
cycle (~30 seconds) and then started back up again. To hot swap a fan, the user should remove
the failed fan, wait at least 30 seconds, and insert the replacement fan. The firmware will then re-
arm the fan sensor. The correct Field Replaceable Unit (FRU)/Sensor Data Record (SDR) must be
installed to ensure proper functionality of the fan control.
Some server boards may only utilize on onboard sensor to regulate fan speed between a nominal
speed and high speed.
