About this file
This document contains a Failure Modes and Effects Analysis (FMEA) for an Integrated Battle Command System (IBCS) hardware component. The FMEA evaluates potential failure modes for a Media Converter Module used in IBCS Relay systems. It identifies 10 possible failure modes including failures of the power supply, internal electronics, data connectors, and signal interfaces. For each failure mode, the FMEA details the potential local and system-level effects, detection methods, safety impacts, and proposes a modified severity classification of Category III-1R given redundancy of IBCS Relay systems. The FMEA was conducted to support the Hardware Low Rate Initial Production/Full Rate Production requirement under solicitation number W31P4Q-20-R-0015. This requirement is for the Department of the Army to produce IBCS hardware items in accordance with technical specifications, address any engineering changes, and maintain approved software and configuration management over the contract period of performance. Questions on this RFP were due by December 10, 2020.
