Attachment 10e.1 – E067 – EtherNet Switch-FMECA.xlsx

This document contains a Failure Modes and Effects Criticality Analysis (FMECA) for components within an Ethernet switch that is part of the Integrated Battle Command System (IBCS). The FMECA identifies several potential failure modes for components including 1000-BASE single monitor transceivers, SFP ports, and a Cisco 48-port switch. For each failure mode, the document describes the potential failure cause, local effects, next higher level effects, and severity classification. It then evaluates compensating provisions like redundancy and indicates whether the severity classification can be reduced. The analysis is intended to support production of IBCS hardware under Solicitation Number W31P4Q-20-R-0015, a draft request for proposal for IBCS Low Rate Initial Production/Full Rate Production. The requirement includes maintaining approved software, firmware, cybersecurity, and engineering changes on existing IBCS hardware components as well as production of new end items.
