Upgrading an

Individual Switch

Using the CLI

1Save the configuration, using the save config command.

2Back up the switch, using the backup system command.

3Copy the new system image onto a TFTP server.

For example, log in to http://www.3com.com using a web browser on your TFTP server and download the image onto the server.

4Copy the new system image file from the TFTP server into a boot partition in the switch’s nonvolatile storage.

You can copy the image file only into the boot partition that was not used for the most recent restart. For example, if the currently running image was booted from partition 0, you can copy the new image only into partition 1.

5Set the boot partition to the one with the upgrade image for the next restart.

To verify that the new image file is installed, type display boot.

6Reboot the software.

To restart a WX switch and reboot the software, type the following command:

reset system [force]

When you restart the WX switch, the switch boots using the new MSS image. The switch also sends the MAP version of the new boot image to MAPs and restarts the MAPs. After a MAP restarts, it checks the version of the new MAP boot image to make sure the boot image is newer than the boot image currently installed on the MAP. If the boot image is newer, the MAP completes installation of its new boot image by copying the boot image into the MAP’s flash memory, which takes about 30 seconds, then restarts again. The upgrade of the MAP is complete after the second restart.
