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.
Status LEDs
The RAU status LEDs can be in one of the states shown in Table 5-3. These LEDs
can be:

There is no off state when the unit’s power is on.
5.4 Faults and Warnings

stored. Only faults are indicated by the faceplate LEDs.
