You can upload a new Boot Image and/or new Firmware to your DWS/DXS-32xx switches in stacking mode all in one attempt.

Please log in to the master switch and follow these instructions:

Step 1 Please type the following command to upload the latest boot version.
If you are already running the latest boot code please skip this step and upload the firmware.

DWS/DXS-32xx# copy tftp://{tftp server ip}/{boot file} unit://*/boot

Please do not reboot the switch at this time

Step 2 Please run the following command to upload the latest firmware.
DWS/DXS-32xx# copy tftp://{tftp server ip}/{image file} unit://*/image

Remember to copy both boot and image files before rebooting the stack.( If applicable)
Since firmware always gets uploaded on the non-active partition you need to run the
following command for each switch.

DWS/DXS-32xx# boot system unit 8 image-2

This is an example considering that this is 8th unit of the stack and non active
image is 2.
You need to run this command for every switch of the stack.
