captive centerpin conductors. Refer to Appendix A for specific information.
5.3 RAU LED Indicators
Upon power up, the RAU goes through a two-second test to check the LED lamps.
During this time, the LEDs blink green/green red/red, letting you visually verify that
the LED lamps and the firmware are functioning properly.
NOTE: Refer to Section 9 for troubleshooting using the LEDs.
