How to setup Daisy-chain mode

In this case, we daisy-chain two IES1248. Please see the figure above. We only set the one connected to the ISP as Daisy-Chain mode. In Daisy-Chain mode, connect the Ethernet Port 1 to the Ethernet backbone and connect the Ethernet Port 2 to another IES1248. Note that we don’t suggest using loop network topology while using daisy-chain mode.
