Layer N Cloud Account and Gateway Registration
Before setting up the SS-015, ensure that a Layer N Cloud account has been created and that a Layer N Gateway has been
registered to that account. Refer to the Layer N Gateway supporting documentation to complete this process.
Important:
If you are adding an SS-015 to a previously registered Layer N Gateway, it is required to update the
Gateway to the latest firmware to ensure the Gateway and SS-015 communicate and operate correctly. Follow the
steps below to update the Gateway.
