Technical Product Specification
Specifications
6.3.1.1 Environmental Assumptions
•
Failure rates are based on a 40° C ambient temperature.
• Applied component stress levels are 50 percent (voltage, current, and/or power).
• Ground, fixed, controlled environment with an environmental adjustment factor equal to 1.0.
6.3.1.2 General Assumptions
• Component failure rates are constant.
• Board-to-system interconnects included within estimates.
• Non-electrical components (screws, mechanical latches, labels, covers, etc.) are not included
within estimations.
• Printed circuit board is considered to have a 0 FIT rate.
6.3.1.3 General Notes
• Method I, Case I = Based on parts count. Equipment failure is estimated by totaling device
failures rates and quantities used.
• Quality Level II = Devices purchased to specifications, qualified devices, vendor lot-to-lot
controls for AQLs and DPMs.
• Where available, direct component supplier predictions or actual FIT rates have been used.
• The SBC MTBF does not include addition of the 2.5” HDD. The product MTBF could be
significantly impacted by adding a HDD. Please contact the HDD manufacturer for specific
component and relevant operational MTBF information.
6.3.2 Power Consumption
The power consumed by the Intel NetStructure

MPCBL0001 High Performance Single Board
Computer SBC is dependent on the type and speed of processors used and the amount of memory
installed. Table 55, “Total Measured Power” on page 98 is based on the use of two Low Voltage

Xeon™ processors. Typical values were obtained by running the Windows* 2000*-based
application “Drive Reaper” against networked shared drives. “Max” values were obtained by
running Intel's DOS* based “Maxpower” utility, version 6.0.
Note: A TriEMS card was installed for all power management tests. The TriEMS dissipates 550 mW
typical.
Note: A TriEMS card was installed for all power management tests. The TriEMS dissipates 550 mW
typical. The power level that was sent to the shelf manager at M3 state is 152W. 10W margin from
the maximum power was an allowance for different model of PMC and DIMMs module.
