An electronic cable system operates as an extension cable to facilitate external viewing of internal infrastructure LED status. A wired cable is provided having a first end and a second end, the first end including a first I/O coupler, LED detectors and a power jack; and the second end including a second I/O coupler and a plurality of LEDs. The plurality of LEDs of the second end illuminate in response to activation of the LED detector of the first end. The first I/O coupler may plug into an internal module of electronic infrastructure, such as a server, to detect operational status of the internal module via the LED detectors. The second I/O coupler may couple to infrastructure housing, permitting the plurality of LEDs to be viewed externally of the housing. The plurality of external LEDs on the infrastructure housing mimic internal (non-viewable) status indicator LEDs of the internal module.
