To upgrade or backup a software image or language file:

1. Click Administration > File Management > Upgrade/Backup Firmware/ Language.
2. Click the Transfer Method. Proceed as follows:
• If you selected TFTP, go to STEP 3.
• If you selected via HTTP/HTTPS, go to STEP 4.
• If you selected via SCP, go to STEP 5.
3. If you selected via TFTP, enter the parameters as described in this step. Otherwise, skip to STEP 4.

Select one of the following Save Actions:

• Upgrade—Specifies that the file type on the device is to be replaced with a new version of that file type located on a TFTP server.
• Backup—Specifies that a copy of the file type is to be saved to a file on another device.

• TFTP Server Definition—Select whether to specify the TFTP server by IP address or domain name.
• IP Version—Select whether an IPv4 or an IPv6 address is used.
• IPv6 Address Type—Select the IPv6 address type (if IPv6 is used). The options are:
• Link Local—The IPv6 address uniquely identifies hosts on a single network link. A link local address has a prefix of FE80, is not routable, and can be used for communication only on the local network. Only one link local address is supported. If a link local address exists on the interface, this entry replaces the address in the configuration.
• Global—The IPv6 address is a global Unicast IPV6 type that is visible and reachable from other networks.
• Link Local Interface—Select the link local interface (if IPv6 is used) from the list.
• TFTP Server IP Address/Name—Enter the IP address or the domain name of the TFTP server.
• (For Upgrade) Source File Name—Enter the name of the source file.
• (For Backup) Destination File Name—Enter the name of the backup file.
4. If you selected via HTTP/HTTPS, you can only Upgrade. Enter the parameters as described in this step.

• Firmware Image—Select this to upgrade the firmware image.
• Language—Select this to upgrade the language file.
• File Name—Click Browse to select a file or enter the path and source file name to be used in the transfer.
5. If you selected via SCP (Over SSH), see SSH Client Authentication for instructions. Then, enter the following fields: (only unique fields are described, for non-unique fields, see the descriptions above)
• Remote SSH Server Authentication—To enable SSH server authentication (which is disabled by default), click Edit. This takes you to the SSH Server Authentication page to configure the SSH server, and return to this page. Use the SSH Server Authentication page to select an SSH user authentication method (password or public/private key), set a username and password on the device (if the password method is selected), and generate an RSA or DSA key if required.

SSH Client Authentication—Client authentication can be done in one of the following ways:

• Use SSH Client System Credentials—Sets permanent SSH user credentials. Click System Credentials to go to the SSH User Authentication page where the user/password can be set once for all future use.
• Use SSH Client One-Time Credentials—Enter the following:

Enter the following fields:

• File Type—Select the destination file type. Only valid file types are shown. (The file types are described in the Files and File Types section).
• SCP Server Definition—Select whether to specify the SCP server by IP address or by domain name.
• IP Version—Select whether an IPv4 or an IPv6 address is used.
• IPv6 Address Type—Select the IPv6 address type (if used). The options are:
• Link Local—The IPv6 address uniquely identifies hosts on a single network link.

• Link-Local Interface—Select the link local interface from the list.
• SCP Server IP Address/Name—Enter the IP address or domain name of the SCP server.
• (For Upgrade) Source File Name—Enter the name of the source file.
• (For Backup) Destination File Name—Enter the name of the backup file.
6. Click Apply. If the files, passwords and server addresses are correct, one of the following may happen:
• If SSH server authentication is enabled (in the SSH Server Authentication page), and the SCP server is trusted, the operation succeeds. If the SCP server is not trusted, the operation fails and an error is displayed.
• If SSH server authentication is not enabled, the operation succeeds for any SCP server.
