Restart Scenarios
9. While the upgrade script file is being downloaded, all IP telephones display the following
message:
HTTP:n sc etag
where n is the number of the IP address obtained from the HTTP server, sc is the status
code of the HTTP response and etag is the value of the ETag header.
10. The script file is processed. The software determines that the telephone's boot code file
name (BOOTNAME) is not the latest version. APPNAME is set to the name of an
application file to replace the boot code. The following message displays while the
application file is downloaded into RAM:
app_filename
n KB received
where n is the number of KBs downloaded.
11. The following message displays while the application file is stored in flash memory:
Saving to flash
n%, x secs
where n is the percentage of the file stored, and x is the number of elapsed seconds. This
usually takes longer than the file download.
12. The following message displays while the telephone is reset so the application file can be
executed:
Restarting...
13. While the boot code is rewritten, the telephone displays:
Updating...
n%, x secs
where n is the percentage of boot code rewritten and x is the number of elapsed seconds
during rewriting.
14. When the new boot code is successfully written into the flash memory, the application
corrupts its own checksum stored in flash. The application then resets the telephone so the
latest system-specific application file can be downloaded.
15. Continue with the next procedure.
