UPD/INIT Pushbutton
6
This pushbutton is used to initialize a controller when it is first installed in a shelf,
to update the system's internal equipment inventory when signals or equipment
are removed from the shelf, and when circuit pack options are changed. The
system automatically detects new equipment or signals added to the shelf. In
these cases, it is not necessary to push the UPD/INIT pushbutton.
An optical switch on the BBG8/BBG8B SYSCTL circuit pack latch causes a
suspension of controller operations and an “F” to be displayed on the controller
panel display when the latch is pulled. Closing the latch causes a controller reset.

The three pushbuttons described previously are used in combinations to perform
