1 Save the configuration, using the save config command.

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

3 Copy 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.

4 Copy 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.

5 Set 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. 

6 Reboot the software. 

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

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.
