Component/Function

SAS Retimer

RMD/ENA jumper. Used to bypass the manageability by the MPCBL0020 SBC IPMC for debugging purposes. Not intended to be use in any field deployment, because changing this default jumper affects the RTM manageability from the ShMC.

Digital/Chassis Ground Jumper

6.4Reliability Specifications

6.4.1Mean Time Between Failure (MTBF) Specifications

Calculation Type:	MTBF/FIT Rate
Standard:	Telcordia* Standard SR-332 Issue 1
Methods:	Method I, Case I, Quality Level II

The calculation results were generated using the references and assumptions listed. This report and its associated calculations supersede all other released mean time between failures (MTBF) and Failure in Time (FIT) calculations of earlier report dates. The reported failure rates do not represent catastrophic failure. Catastrophic failure rates will vary based on application environment and features critical to the intended function.

Table 18. Reliability Estimate Data

Failure Rate (FIT)	913 failures in 109 hours
MTBF	1,095,000 hours

6.4.1.1Environmental Assumptions

•Failure rates are based on a 40° C ambient temperature.

•Applied component stress levels are 50% (voltage, current, and/or power).

•Ground, fixed, controlled environment with an environmental adjustment factor equal to 1.0.

6.4.1.2General 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.
