SMBus Monitoring Interface

The 600W is compatible with both SMBus 2.0 'high power' and I
This bus operates at 3.3V. The SMBus pull-ups are located on the server board.
The SMBus provides power monitoring, failure conditions, warning conditions, and FRU data.
Two pins have been reserved on the connector to provide this information: one pin for the Serial
Clock (PSM Clock) and one pin for the Serial Data (PSM Data). Both pins are bi-directional and
are used to form a serial bus.

System Cooling

4.1

Fan Configuration

The cooling sub-system in the Server Chassis SC5275-E consists of two system fans and one
power supply fan. A 92mm x 25mm fan located in the front of the fixed hard drive cage draws
fresh air into the chassis from the front and provides cooling for the hard drive bay. A 120mm x
38mm fan provides cooling at the rear of the chassis, exhausting warm air out of the system.
The power supply fan assists in drawing air through the peripheral bay area, through the power
supply and exhausting it out the rear of the chassis.
In addition to these pre-installed fans, locations for three additional fans are provided for
customized configurations. Intel does not provide order part numbers for these customizable fan
options. A 120mm fan can be mounted to the rear of the PCI card guide and provide additional
cooling to the PCI card area and two 80mm fans can be mounted at the front of the chassis to
the right of the hard drive bay opening to provide more cooling.

Fan Control

The fans provided in the Server Chassis SC5275-E contain a tachometer signal that can be
adjusted by the Server Management subsystem for the Intel® Server Board SE7520BD2 or
SE7320SP2. See the specific baseboard Technical Product Specification for details on how this
feature works.
