46 RackSwitch G8000: Application Guide
To load a new software image to your switch, you will need the following:
• The image and boot software loaded on an FTP or TFTP server on your net-
work.
Note:
Be sure to download both the new boot file and the new image file.
• The hostname or IP address of the FTP or TFTP server
Note:
The DNS parameters must be configured if specifying hostnames.
• The name of the new software image or boot file
When the software requirements are met, use one of the following procedures to
download the new software to your switch. You can use the IBM N/OS CLI, the
ISCLI, or the BBI to download and activate new software.
Loading Software via the IBM N/OS CLI
1. Enter the following Boot Options command:
2. Enter the name of the switch software to be replaced:
3. Enter the hostname or IP address of the FTP or TFTP server.
4. Enter the name of the new software file on the server.
The exact form of the name will vary by server. However, the file location is
normally relative to the FTP or TFTP directory (usually
/tftpboot
).
5. Enter your username for the server, if applicable.
If entering an FTP server username, you will also be prompted for the password.
The system then prompts you to confirm your request. Once confirmed, the
software will load into the switch.
6. If software is loaded into a different image than the one most recently booted,
the system will prompt you whether you wish to run the new image at next boot.
Otherwise, you can enter the following command at the Boot Options#
prompt:
The system then informs you of which software image (

) is
currently set to be loaded at the next reset, and prompts you to enter a new
choice:
