Working with Software Images
The info.ver file is always at the end of the tar file and contains the same information as the info file.
Because it is the last file in the tar file, its existence means that all files in the image have been
downloaded.
Note The tar file sometimes ends with an extension other than .tar.
Copying Image Files by Using TFTP
You can download an WMIC image from a TFTP server or upload the image from the WMIC to a TFTP
server.
You download an WMIC image file from a server to upgrade the WMIC software. You can overwrite the
current image with the new one.
You upload an WMIC image file to a server for backup purposes; this uploaded image can be used for
future downloads to the same or another device of the same type.

Preparing to Download or Upload an Image File by Using TFTP
Before you begin downloading or uploading an image file by using TFTP, perform these tasks:
• Ensure that the workstation acting as the TFTP server is properly configured. On a Sun workstation,
make sure that the /etc/inetd.conf file contains this line:
tftp dgram udp wait root /usr/etc/in.tftpd in.tftpd -p -s /tftpboot
Make sure that the /etc/services file contains this line:
tftp 69/udp
Note You must restart the inetd daemon after modifying the /etc/inetd.conf and /etc/services files.
To restart the daemon, either stop the inetd process and restart it, or enter a fastboot
command (on the SunOS 4.x) or a reboot command (on Solaris 2.x or SunOS 5.x). For more
information on the TFTP daemon, refer to the documentation for your workstation.
• Ensure that the WMIC has a route to the TFTP server. The WMIC and the TFTP server must be in
the same subnetwork if you do not have a router to route traffic between subnets. Check connectivity
to the TFTP server by using the ping command.
• Ensure that the image to be downloaded is in the correct directory on the TFTP server (usually
/tftpboot on a UNIX workstation).
• For download operations, ensure that the permissions on the file are set correctly. The permission
on the file should be world-read.
• Before uploading the image file, you might need to create an empty file on the TFTP server. To
create an empty file, enter the touch filename command, where filename is the name of the file you
will use when uploading the image to the server.
