  Working with Software Images
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.
  •
During upload operations, if you are overwriting an existing file (including an empty file, if you had 
to create one) on the server, ensure that the permissions on the file are set correctly. Permissions on 
the file should be world-write.
Downloading an Image File by Using TFTP
You can download a new image file and replace the current image or keep the current image. 
Caution
For the download and upload algorithms to operate properly, do not rename image directories.
To download a new image from a TFTP server and overwrite the existing image, follow these steps, 
beginning in privileged EXEC mode:
