Administering The Upgrade - Avaya G430 Deploying And Upgrading

Upgrading IP phone configuration and firmware files
• Use the copy scp SW_imageB command to upgrade the Branch Gateway firmware into
Bank B from an SCP server

Administering the upgrade

When using supported IP phones with the Branch Gateway, 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.
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. Upon reset, any
phone image files stored in RAM are erased.
Note:
Previous releases of TFTP server required the configuration of the DHCP server 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.
