Adding a new Gateway to your network requires the appliance to contact the Riverbed SteelConnect Manager which provides the initial configuration.
In a scenario where no DHCP server is available in the existing network, or a static IP address should be assigned to the new Gateway, offline provisioning can be used.
You can set up the configuration on your SC, even if the hardware is currently not present at the related site.
At least the serial number of the new appliance will be required to create the offline provisioning configuration file.
