About this file
This document contains a red-line failure modes and effects criticality analysis (FMECA) for an isolation router component of an Integrated Battle Command System.
The FMECA identifies 29 potential failure modes for the isolation router, including erroneous LED indications, faulty fans, switches, opens, shorts, data errors, electrical overstress, under/over voltages and more. It analyzes the effects of each failure mode at the component, next higher system, and major end item levels. Compensating provisions and operator observations are noted. The majority of failures are categorized as Category III, with some Category IV. The solicitation seeks production of IBCS hardware end items in accordance with supplied technical data packages and specifications, and may require engineering changes for obsolescence, new capabilities or export. Questions are due by December 10, 2020 for the Army Materiel Command contract.
