Direct Operating System Downloads
Initiate the download by executing the proper
command(s) in the download tool running on
the host computer (when the receiving
terminal is ready to receive the direct OS
download). The data transfer operation starts,
and the status messages are displayed on the
terminal screen.
The progress of the download is indicated by
a series of ten asterisks (each asterisk
indicates that 10% of the download is
complete). When the last asterisk is displayed,
the download is complete.
To stop the download operation, press the
CANCEL key. The terminal restarts
automatically.
When the OS download is complete, the
terminal restarts automatically. The file
authentication module on the receiving
terminal begins to check for new certificate
(*.crt) and signature (*.p7s) files included
in the download. These special files then
process one at a time; certificates process
first, then signature files.
When the file authentication module is
invoked, the status display informs you of the
progress of the file authentication process. If
file authentication succeeds for a specific
certificate, the "
AUTHENTIC
displayed directly below the certificate
filename. If file authentication fails for a
specific certificate, the "
FAILED
displayed for five seconds below the filename
and the terminal beeps three times, allowing
you to note which certificate failed to
authenticate.
The authentication process then continues to
the next certificate until all new certificates are
checked.
