About this file
This document contains a Failure Modes and Effects Criticality Analysis (FMECA) for an R031 Black Router and related federal contract opportunity. The FMECA analyzes potential failure modes for components of the R031 Black Router such as the router internal power supply, router processor, power connector, and Ethernet connectors. It identifies failure effects at the component, next higher assembly, and end item levels. The document assigns severity classifications and calculates failure rates. It considers design modifications to reduce severity classifications.
The related federal contract opportunity is a draft Request for Proposal for the Integrated Battle Command System Low Rate Initial Production/Full Rate Production segment. The requirement involves producing IBCS hardware end items according to technical data packages and specifications, as well as maintaining approved software/firmware updates, cybersecurity, and authority to operate on existing hardware. Engineering changes may be required for obsolescence, new capabilities, and export. The draft RFP is not currently seeking proposals and is for comment only. The solicitation number is W31P4Q-20-R-0015 and it is issued by the Department of the Army Materiel Command Contracting Command Redstone Arsenal.
