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

To use 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 the FTP or TFTP protocol to upload 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 Installation and Upgrades for the Avaya G250
Media Gateway, 03-300434 or Installation and Upgrades for 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 uploading new versions.
By default, when you turn on or reset the G250/G350, the G250/G350 loads firmware from
Bank B. To change the default bank from which firmware is loaded during startup, type the set
boot bank command. For example, to configure the G250/G350 to load firmware from Bank A
on startup, type set boot bank bank-A. After typing the set boot bank command, you
must type the copy running-config startup-config command to save the change.
Now, when you reset the G250/G350, it will load firmware from Bank A.
