COMP (Complete) - shows when the software installation is completed.
(d)
RDY (Ready) - shows when the disk is in the disk drive and the ADL is ready to install the software in the component. 1) If the RDY indication flashes, then the data loader is in
standby mode while it waits for the component to validate the data.
