3.4.1 Localising an RU fault

Normally, an RU fault is located with the use of the InLite Supervisor software

application. However, an RU has two LEDs (green and red) that are visible

externally. The LEDs are illuminated when the RU is in a fault state and not

functioning.

An RU fault is identified using the Supervisor software.

The RU LEDs (2) are located under the cable cover of the RU mounting rack. It

is advisable to remove the cable cover so the two LEDs can be seen properly.
