About this file
This document contains a Failure Modes and Effects Criticality Analysis (FMECA) for an isolation router and related federal contract opportunity. The FMECA identifies 29 potential failure modes for the router including erroneous LED indications, faulty switches, faulty fans, shorts, data bit errors, electrical overstress, data word failures, failure to operate at prescribed times, opens, and faulty components. It analyzes the effects of each failure mode on the router and higher level systems. The related federal contract opportunity is a draft request for proposal for the Integrated Battle Command System hardware low rate initial production and full rate production. It involves producing IBCS hardware in accordance with technical data packages and specifications, maintaining approved software and firmware updates, and executing any engineering changes for obsolescence, new capabilities, or export considerations. The solicitation number is W31P4Q-20-R-0015 and it is issued by the Department of the Army Materiel Command Contracting Command at Redstone Arsenal.
