Upgrading Controller Software
Follow these steps to upgrade the controller software using the CLI.
You can also update the controller software using the GUI or through a wireless connection. However,
Note
in these cases, you will lose your connection to the controller sometime during the update process. For

software.
Step 1

If you are downloading through the Service port, the TFTP server must be on the same subnet as the
service port, because the service port is not routable.
If you are downloading through the DS (Distribution System) network port, the TFTP server can be
on the same or a different subnet, because the DS port is routable.
The TFTP server cannot run on the same computer as WCS because WCS and the TFTP server use
the same communication port.
