Upgrading The Ip Telephone - Avaya G350 Installing And Upgrading

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.
There are four image banks, supporting two IP phone images in RAM, provided the combined
file sizes do not exceed the RAM allocation for TFTP server. The maximum size for a booter
application or phone application file is 4.5 MB. Thus, it is possible that in some cases, the
allocation may only suffice for one complete IP phone image and not two.
!
CAUTION:
To activate a change in RAM allocation to the TFTP server, reset is required.
CAUTION:
Upon reset, any phone image files stored in RAM are erased.
Note:
Previous releases of TFTP server required the configuration of the DHCP server
Note:
option 43/176 with the named value pair TFTPDIR=/phonedir/ in order to allow
the IP phone to access the files in this directory. This configuration is still
supported but is no longer required.

Upgrading the IP telephone

IP phone upgrade files include script files, boot images files, and phone application image files.
You can download these files to a remote FTP/TFTP/SCP server, or you can download them to
a laptop and copy them to a USB device. You can then copy the upgrade files to the G350.
Note:
An SCP server can be used for copying the script files, which do not exceed
Note:
128 KB, but cannot be used for copying image files.
You cannot use SCP to copy 46xxsettings files as they exceed 128 KB.
