Figure 11. Shipping Bracket Placement
With no shipping bracket installed, the air duct has support for the addition of up to two SSD Storage
devices mounted to the air duct via fastener screws. Mounting standard hard disk drives to the air duct is
NOT a supported configuration. Mounting hard disk drives to the CPU air duct may cause data loss,
performance degradation, and premature drive failures.
High power add-in cards that require up to 300W can be supported. A total system power budget should be
calculated to determine if the power draw of the desired system configuration meets the power limits of the
installed power supplies. A power budget tool for the specified system can be downloaded from
http://www.intel.com/support .
The latest posted system software updates must be installed on the system to ensure proper fan speed
control is enabled. The latest system update package can be downloaded from the following Intel web site:

Intel® Server System R2000WT family Fan Speed Control
The following IPMI script was developed to provide fan speed control for the Intel® Server System R2000WT
product family. The script changes the default Pulse Width Modulation (PWM) offset of the system fans to a
value that provides enough airflow to maintain the ambient temperature of the VCA card processors below
96°F. The temperature is retrieved by calling ‘vcactl temp’ and then as the temperature goes above 95
degrees the fan speed increases. If the temperature drops below 90 degrees the fan speed will decrease.
The amount it increases is proportional to how much beyond that threshold the temperature spikes. This
offset is beyond the fan speed control already implemented in the BMC so not to impact other components
the BMC manages.
