Front panel annunciators

There are three illuminable annunciators on the MCDU front panel:
-    FAIL: This  annunciator  comes on (amber) when the MCDU has failed.

-    MCDU MENU: This  annunciator  comes on (white) when a system linked to the MCDU requests the display.

-    FMGC: This  annunciator  comes on when the FMGC is not active and when it has sent an important message

Top panel annunciators

There are five illuminable annunciators across the top of the MCDU front panel of which one is spare and not utilized. The spare  annunciator  is unlabeled but it contains an amber light.
(a) FM1 and FM2

The FM failure annunciators at the top of the MCDU indicate when a FM failure occurs.
The FM1 failure light on MCDU1 and/or MCDU2 comes on (amber) if FM1 is the selected FM, the MCDU BRT knob is at ON and the FM1 subsystem identifier word (label 172) is not received for three seconds by the MCDU.
Likewise, the FM2 failure light on MCDU1 and /or MCDU2 comes on (amber) if FM2 is the selected FM, the MCDU BRT knob is at ON and the FM2 subsystem identifier word is not received for three seconds by the MCDU.
The corresponding FM failure  annunciator  on MCDU3 comes on only if MCDU3 operates as a backup to MCDU1 or MCDU2. It comes on only in the context of the failed MCDU selected FM.
Additionally, a MCDU never has both its FM failure annunciators on. The FM failure annunciators are off when an identifier word is received from the appropriate FM.
(b) RDY

This  annunciator  comes on (green) when the MCDU passes its long-term power up or power off reset test after its BRT knob is turned to OFF.
(c) IND

This  annunciator  comes on (amber) when the selected FM detects an independent operation (loss of dual mode) while both FMs are healthy. If either FM is failed, the  annunciator  is not on, regardless of the state of the intersystem bus.
