Upgrading the System Image

To upgrade the switch from one MSS version to another, use the procedure in this section. For a
given release, there may be notes and cautions that apply only to that release. Consequently, before
upgrading to a new software image, you should also consult the release notes for that release.

Preparing the Switch for the Upgrade

Caution: Save the configuration, then create a backup of your switch files before you upgrade the
switch. D-Link recommends that you make a backup of the switch files before you install the upgrade. If
an error occurs during the upgrade, you can restore your switch to its previous state.
Use the following command to save the configuration. Unsaved changes will be lost during the upgrade
procedure.
save config [filename]
If the switch is running MSS Version 3.2.2 or later, you can use the following command to back up the
switch's files:
backup system [tftp:/ip-addr/]filename [all | critical]
To restore a switch that has been backed up, use the following command:
restore system [tftp:/ip-addr/]filename [all | critical] [force]
Note: If you have made configuration changes but have not saved the changes, use the save config
command to save the changes, before you back up the switch.

Upgrading an Individual Switch Using the CLI

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.dlink.com/services/ 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 show boot.
6. Reboot the software. To restart a DWS-1008 switch and reboot the software, type the
following command: reset system [force]
