Downloading the Supervisor Engine Images Using FTP or TFTP

Note If you have a redundant supervisor engine, you cannot download a system image directly from an FTP
or 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.

Verify that the workstation acting as the TFTP server is configured properly. When using TFTP on
a Sun workstation, verify that the /etc/inetd.conf file contains this line:
tftp dgram udp wait root /usr/etc/in.tftpd in.tftpd -p -s /tftpboot
Verify that the /etc/services file contains this line:
tftp 69/udp
When using FTP on a Sun workstation, verify that the /etc/inetd.conf file contains this line:
ftp stream tcp nowait root /usr/sbin/tcpd in.ftpd
Verify that the /etc/services file contains this line:
ftp 21/udp
You must restart the inetd daemon after modifying the /etc/inetd.conf and /etc/services files.
Note
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 FTP or TFTP
daemon.
Verify that the switch has a route to the FTP or TFTP server. The switch and the FTP or TFTP server
must be in the same subnetwork if you do not have a router to route the traffic between the subnets.
Check connectivity to the FTP or TFTP server by entering the ping command.
Verify that the software image to be downloaded is in the correct directory on the FTP or TFTP
server.
Verify that the permissions on the file are set correctly. The permissions on the file should be set to
world-read.
Note that 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.
