Overview

A Gigabit Ethernet Data Multiplex System Interior Communications electrician performs preventive and corrective maintenance using self diagnostics, built in test equipment, and supporting documentation. The electrician troubleshoots and isolates faults, tests, aligns, and calibrates equipment, repairs or replaces faulty components, and operates connected consoles to verify system connectivity aboard designated destroyers.

Core Skills

  • Fault isolation using built-in diagnostics
  • Component repair, alignment, and calibration
  • Connected-system console testing for connectivity

Civilian Career Paths

Career associations are editorial assessments of the cited evidence, not an official crosswalk unless the evidence explicitly says so. O*NET supplies civilian occupation information, not proof of a military match. Related experience does not confer civilian qualifications. Tasks and tools below describe civilian work, not military training.

Telecommunications Equipment Installers and Repairers, Except Line Installers

GEDMS fault isolation, component repair, and connected-system testing transfer directly to telecommunications equipment troubleshooting and repair verification.

How to prepare: Complete a hands-on telecommunications equipment lab that uses circuit diagrams and test meters to isolate a fault and verify the repair against specifications.

What the civilian work involves
  • Test circuits and components of malfunctioning telecommunications equipment to isolate sources of malfunctions, using test meters, circuit diagrams, polarity probes, and other hand tools.
  • Test repaired, newly installed, or updated equipment to ensure that it functions properly and conforms to specifications, using test equipment and observation.
Civilian tools and software (examples)
  • Cisco IOS

Electrical and Electronics Repairers, Commercial and Industrial Equipment

Preventive and corrective GEDMS maintenance, diagnostic testing, and component calibration transfer to commercial and industrial electronics repair.

How to prepare: Take a hands-on industrial electronics troubleshooting course that includes equipment testing and recording repair and calibration results in a maintenance log.

What the civilian work involves
  • Test faulty equipment to diagnose malfunctions, using test equipment or software, and applying knowledge of the functional operation of electronic units and systems.
  • Maintain equipment logs that record performance problems, repairs, calibrations, or tests.
  • Set up and test industrial equipment to ensure that it functions properly.
Civilian tools and software (examples)
  • Circuit evaluation software
  • Computerized maintenance management system CMMS
