Administering the Upgrade

When using supported IP phones with the G350, the IP phones require the downloading of the
settings file and the upgrade scripts. These files are stored in the script banks in NVRAM and
are preserved in the event of a reset or power failure. There are two script banks.
In addition, each phone can have a booter application and a phone application. There are four
banks that can store up to two phone images (booter and phone application files) at any given
time. Since the image files are stored in RAM, a reset or power failure erases these files. The
image files are used only for upgrading the IP phone, so there is no need to store them
permanently. However, the scripts are used by the IP phones when they are reset, and are
therefore stored in NVRAM. You can upgrade up to two types of phones and then release the
banks for use with another IP phone type.
There are cases where the image files are the same for different IP phone types. In these
cases, you can download the image files once for the IP phones that use the same image. The
scripts are global to all the supported IP phone images.
You can download and then upload setting script files in order to update their content. It is not
recommended to change the upgrade script.
By default, the RAM allocation for TFTP server is 10 MB. You can increase the RAM allocation
for TFTP server to up to 11.264 MB at the expense of the Sniffer cache application. The
maximum RAM for both applications is 12 MB.
