Notes about downloading software
If there is no Front Panel Control software installed in the system (as would be the case when the display units control board is
replaced), the Service Application automatically downloads the Front Panel Controls software at startup. During the download
the two display unit LEDs will flash and the display speaker will sound an alarm tone to indicate that Software Download is
proceeding.
To ensure that all software versions on the system are compatible, the end result of "Download All" or "Download New" will be
the same. The software loaded on the machine will exactly match what is on the card. Be sure to have the latest/correct version
of software before attempting a download to avoid inadvertent overwrites of newer software with an older version.
If, during the "Download New" process, the compatibility checker detects a newer version of software component on the system,
a "Notice" appears on the screen that asks you to confirm the downgrade.
"Download All" will download all compatible software from the card to the system without issuing a notice that newer version of
software component may be on the system.

The Compact Flash card includes only the latest software for each subsystem along
with the diagnostic application.
As each subsystem software segment is being downloaded, the following status
messages note the state of each subsystem and the result of the download:
• In App - System is running its application code; not ready for download.
• Ready - System is in its boot code; ready for download.
• Loading - System is accepting download data.
• Done - Software download has completed successfully.
• Fail - Software download did not complete successfully. A "Fail" message will require
reloading of the software; or repair of the system may be necessary.
• Skipped - Software download was bypassed.
• No Comm - The subsystem is not communicating with the HPDU.
If the subsystem is communicating but the HW Rev or current SW Rev are not known,
dashes will appear for those values.
As the software loads, an activity bar at the bottom of the screen shows the download
progress for each subsystem.
When all the required subsystem software is download, the following message appears
on the screen. You must shut down the system to exit the download function.
DOWNLOAD IS COMPLETE.
