Intel MPCBL0001 Power Consumption, Environmental Assumptions, General Assumptions, General Notes

Intel NetStructure® MPCBL0001 High Performance Single Board Computer

Contents

6.3.1.1Environmental 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.

6.3.1.2General 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.

6.3.1.3General 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.

6.3.2Power 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 61, “Total Measured Power” on page 108 is based on the use of two Low Voltage
	Intel® 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.
Table 61.	Total Measured Power
	Memory	Dual 2.0 GHz (400 Mhz FSB)
	8GByte (Four 2-GByte DIMMs)	Typical power = 127 W
		Max power = 142 W
