FMCS -CDU POWER INTERFACE
General
These power buses supply 28v dc power to a CDU through an insertion switch:
*
Captain’s flight instrument bus (L CDU)
*
Left bus (C CDU)
*
Right bus (R CDU).
Insertion Switch
When you remove the CDU from the CDU mount, the insertion switch opens and removes power from the CDU.
When you put the CDU into the CDU mount, the insertion switch closes and supplies power to the CDU.
The insertion switch is a spring loaded switch near the connector on the CDU mount.
