**VERIFYING FILES**
CHECK CERTIFICATE
FILENAME.CRT
*AUTHENTIC*
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* message is
displayed directly below the certificate
filename. If file authentication fails for a
specific certificate, the
*FAILED* message is
displayed for five seconds below the filename
and the terminal beeps three times, allowing
you to note which certificate failed to
authenticate.

COMPARE SIGNATURE
FILENAME.P7S
FILENAME.OUT
*AUTHENTIC*
The authentication process then continues to
the next certificate until all new certificates are
checked.

<application prompt>
When all new signature files are
authenticated, the terminal restarts and begins
processing the new OS (full download) or it
returns control to terminal manager (partial
download).
Because a full OS download clears the RAM,
all terminal applications, related certificates,
and signature files must download to the
terminal when performing this type of
download.
