Feature Summary
Proper operation of the thermal sensors is critical to system health and availability and
protection of user data. The power supply fan cannot be monitored.
Enclosure management is performed by a SMSC SCH5027D part with an integrated hardware
monitor controller. The SMSC component monitors various aspects of the storage enclosure.
The enclosure management controller supports the following features:

1.4.1 Fan Connector and Control

The 4-pin fan connector supports a standard fan with integrated fan speed control on the fan
itself for better fan life. The first 3 pins of this 4-pin fan connector are backward compatible with
a traditional 3-pin fan connector without PWM fan speed control but a 3-pin fan should not be
used in the Intel® Entry Storage System SS4200-E. A fan spare kit is available from your
supplier which contains the correct fan.
Fan control is managed through the SMSC SCH5027D Super I/O and enclosure management
component. In the event of a fan failure the system will shutdown to prevent an over
temperature situation. For additional information refer to Section 3, System Cooling Fans.
