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.

•

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.

•

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.

A

SAS Retimer

B

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.
