About this file
This document contains an attachment to a federal solicitation for the Integrated Battle Command System (IBCS) Low Rate Initial Production/Full Rate Production segment.
The attachment provides a Failure Modes, Effects and Criticality Analysis (FMECA) for the R034 Media Converter Power Supply component of IBCS. It details three potential failure modes for the power supply: an open or short in the input power circuit, or failure of the output power. For each failure mode, the analysis describes the local, next higher system level, and end item effects. It also provides severity classifications, detection methods, and notes that compensating provisions exist due to redundancy. The federal solicitation seeks production of IBCS hardware in accordance with supplied technical data packages and specifications. It is issued by the Department of the Army Materiel Command Contracting Command located at Redstone Arsenal. Questions regarding the solicitation are due by December 10, 2020 at 4pm Central Time.
