Software And Firmware Upgrades; Managing The Firmware Banks - Avaya G250 Administration Manual

To use FTP/TFTP file transfer, you need to have an FTP server or TFTP server on your
network.
Note:
If you use an FTP server, the G250/G350 prompts you for a username and
Note:
password when you enter a command to transfer a file. Also, when opening an
FTP connection to the S8300, all anonymous FTP file transfers are restricted to
the /pub directory. Permission for anonymous FTP users to create files in other
directories is denied.

Software and firmware upgrades

You can upgrade software on the Avaya G250/G350 Media Gateway. Software used to control
the Avaya G250/G350 Media Gateway itself and media modules installed on the G250/G350 is
called firmware. Use a USB device or the FTP or TFTP protocol to download a new version of
software or firmware. You can upgrade the following types of software and firmware:
Firmware for the Avaya G250/G350 Media Gateway
●
Java applet for Avaya G350 Manager (G350 only)
●
Firmware for media modules
●
Note:
You can also use the G250/G350 to upgrade the firmware and configuration files
Note:
for IP phones. For details, see Installing and Upgrading the Avaya G250 Media
Gateway, 03-300434 or Installing and Upgrading the Avaya G350 Media
Gateway, 03-300394.

Managing the firmware banks

The G250/G350 has two firmware banks:
Bank A
●
Bank B
●
Each firmware bank contains a version of the G250/G350 firmware. These may be different
versions. The purpose of this feature is to provide software redundancy. If one of the versions
becomes corrupted, you can reset the G250/G350 using the other version. This is particularly
important when downloading new versions.
Displaying firmware versions in the banks
Use the show image version command to display the firmware version of the image on both
memory banks of the device.
