Attachment 10a.9 – R015 PDU Assembly-FMECA.xlsx

This document contains a Failure Modes and Effects Criticality Analysis (FMECA) for a Power Distribution Unit Assembly component of an Integrated Battle Command System.

The FMECA identifies potential failure modes for circuit breakers across several subcomponents, including Media Converters, SCIM, Timing Units, IGRMs, Network Switches, and Alternate Media devices. Failure effects are described at the component, next higher system, and end item levels. Failure causes include switch contact damage, hardware failures, and degraded operation. Mitigations relying on redundant relays are proposed to reduce severity classifications from Categories I-II to Categories III-1R or III-2R. Detection methods include visual indicators and built-in-test capabilities. The Army Materiel Command is seeking comments on a draft RFP for Low Rate Initial Production and Full Rate Production of IBCS hardware end items per supplied Technical Data Packages and the Critical Item Development Specification. Engineering changes may be required for obsolescence, new capabilities, and export considerations.
