Interposer PCA
This PCA provides the drive interface to control the loading and unloading of the
optical disk drives from the controller PCA. Drive status is read from here and all
ejects are issued from registers on this PCA.
Figure 6–3 Interposer PCA
The drive register interface is read by the controller through the 50-pin cable
connector. The cable connector on the top edge of the interface is a controller
PCA pass-though connection to the control panel.
Power and data connections for four drives are installed on all jukeboxes,
whether four drives are installed or not. Installing cables in this way prepares
two-drive units for possible upgrade to four-drive units. Two sets of two 20-pin
data connectors and two sets of 8-pin power connectors are installed on the PCA.
An input connector and two output connectors route fan power to the fans
located just above the PCA. If neither of the fans are plugged in to the interposer
PCA or are inoperative, the 5/12V power supply will shut down. Loss of fans is
detected in the 5/12V power supply; not on the interposer PCA.
There is a mailslot status connector on the left side and a connector to route
power to the two picker vertical path clear (starwars) transmitters.
