4. If the DHCP server did not provide the information to the
AT-VP504E FXS, configure the
tftpServerEmergencyStaticHost variable in the tftpGroup
category with the current address of the PC that runs the
TFTP server.
For example, set the variable with a valid IP address such as
192.168.0.2.
5. Configure the tftpEmergencyFileName variable with the
current name of the emergency software that will be
downloaded into the AT-VP504E FXS.
You can use any name you want. However, make sure that
the name you enter matches the name of the file located on
the TFTP server.
6. Disable the AT-VP504E FXS by setting the apaCmdMode
variable to 1.
7. Initiate the image download by setting the apaCmdDownload
Software
variable to 1.
This will start the download process.
8. Query the tftpDownloadStatus variable and see if it is reset to
1. If yes, then the update is done.
If you are using a Syslog Daemon, you will receive messages
that inform you when the update is completed and that you
can now reboot the AT-VP504E FXS. The LEDs will also
indicate the completion of the download process. See “LED
States” on page 48 for more details.
The AT-VP504E FXS will stop responding for a few seconds
while the image is written to the EEPROM memory. This is
normal and it may take 20 to 30 seconds before the
AT-VP504E FXS comes back and starts responding again.
Warning: Never shutdown the AT-VP504E FXS manually while in the
In Progress state of the image download process, because the image
may be partially written to the EEPROM and the AT-VP504E FXS will
be unable to restart.
