Downloading Supervisor Engine Images Using TFTP

If you have a redundant supervisor engine, you cannot download a system image directly from a
Note
TFTP server to the Flash memory on the standby supervisor engine. When you download the image
to the active supervisor engine, the standby supervisor engine synchronizes automatically with the
new image. In addition, you cannot copy an image from the standby supervisor engine to the active
supervisor engine.
To download a supervisor engine software image to the switch from a TFTP server, perform these steps:
Copy the software image file to the appropriate TFTP directory on the workstation.
Step 1
Log into the switch through the console port or through a Telnet session. If you log in using Telnet, your
Step 2
Telnet session disconnects when you reset the switch to run the new software.
Enter the copy tftp flash command. When prompted, enter the IP address or host name of the TFTP
Step 3
server and the name of the file to download. On those platforms that support the Flash file system, you
are also prompted for the Flash device to which to copy the file and the destination filename.
The switch downloads the image file from the TFTP server to the specified Flash device.
Note
Modify the BOOT environment variable using the set boot system flash device:filename prepend
Step 4
command, so that the new image boots when you reset the switch. Specify the Flash device (device:) and
the filename of the downloaded image (filename).
Step 5 Reset the switch using the reset system command. If you are connected to the switch through Telnet,
your Telnet session disconnects.
During startup, the Flash memory on the supervisor engine is reprogrammed with the new Flash code.

You must restart the inetd daemon after modifying the /etc/inetd.conf and /etc/services
Note
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). Refer
to the documentation for your workstation for more information on using the TFTP
daemon.
Ensure that the switch has a route to the TFTP server. The switch 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 using the ping command.
Ensure that the software image to be downloaded is in the correct directory on the TFTP server
(usually /tftpboot on a UNIX workstation).
Ensure that the permissions on the file are set correctly. Permissions on the file should be
world-read.
A power interruption (or other problem) during the download procedure can corrupt the Flash code.
If the Flash code is corrupted, you can connect to the switch through the console port and boot from
an uncorrupted system image on a Flash PC card.
The switch remains operational while the image downloads.
