IRU Power Supply LEDs

007-6402-001
There are a number of LEDs on the front of the IRUs that can help you detect, identify and
potentially correct functional interruptions in the system. The following subsections describe
these LEDs and ways to use them to understand potential problem areas.
Each power supply installed in an IRU has a bi-color status LED. The LED will either light green
or amber (yellow), or flash green or yellow to indicate the status of the individual supply. See
Table 7-2 for a complete list.
