About this file
This document contains a preliminary failure modes and effects analysis (FMECA) for an E151 media converter component used in a shelter for the WIN-T AXX system. The analysis identifies four potential failure modes: does not operate, intermittent operation, degraded functional operation, and no failure. Failure causes are listed as hardware or software issues. Effects are described at the component, next higher system, and overall shelter levels. Severity classifications are proposed and mitigation from redundant equipment carriers is noted. Compensating provisions like operator observation and visual indicators are identified. The related opportunity appears to be a draft request for proposal for low rate initial production and full rate production of Integrated Battle Command System hardware end items. The RFP seeks to produce hardware to technical data packages and specifications, and may require engineering changes for obsolescence, new capabilities, or export. No proposals are being sought from the draft posted.
