SSL analog products with network adapters (Sigma, Nucleus*, Matrix, AWS, and Duality) do not do stateless autoconfiguration or automatic private IP addressing (APIPA).
In other words, if they are left in DHCP mode but not connected to a DHCP server, they will not generate their own IP in the range 169.254.nnn.nnn, they will go into an invalid state such as 0.0.0.0.
However, link-local addressing can be a convenient way to quickly connect SSL devices.
For this reason, changing your SSL's default fixed IP address to a link-local address such as 169.254.1.2 has more benefits than the default of 192.168.1.2.
The major benefit is you can leave your computer's adapter in DHCP mode and connect the SSL directly to your computer without any extra IP setup on the users part.
*The Nucleus Dante adapter does do stateless autoconfiguration, as it is made by Audinate. It is the SSL control portion (as managed in the Remote app) that does not do autoconfig.
