GE Multilin F60 Feeder Protection System 5-275 SETTINGS 5.2 PRODUCT SETUP5c) ETHERNET NETWORK TOPOLOGYWhen using more than one Ethernet port, configure each to belong to a different network or subnet using the IP addressesand mask, else communication becomes unpredictable when more than one port is configured to the same subnet.Example 1IP1/Mask1: 10.1.1.2/255.255.255.0 (where LAN 1 is 10.1.1.x/255.255.255.0)IP2/Mask2: 10.2.1.2/255.255.255.0 (where LAN2 is 10.2.1.x/255.255.255.0)IP3/Mask3: 10.3.1.2/255.255.255.0 (where LAN3 is 10.3.1.x/255.255.255.0)Example 2IP1/Mask1: 10.1.1.2/255.0.0.0 (where LAN1 is 10.x.x.x/255.0.0.0)IP2/Mask2: 11.1.1.2/255.0.0.0 (where LAN2 is 11.x.x.x/255.0.0.0)IP3/Mask3: 12.1.1.2/255.0.0.0 (where LAN3 is 12.x.x.x/255.0.0.0)Example 3 — IncorrectIP1/Mask1: 10.1.1.2/255.0.0.0IP2/Mask2: 10.2.1.2/255.0.0.0IP3/Mask3: 10.3.1.2/255.0.0.0This example is incorrect because the mask of 255.0.0.0 used for the three IP addresses makes them belong to the samenetwork of 10.x.x.x.Single LAN, No RedundancyThe topology shown in the following figure allows communications to SCADA, local configuration/monitoring throughEnerVista, and access to the public network shared on the same LAN. No redundancy is provided.Figure 5–4: NETWORK CONFIGURATION FOR SINGLE LAN
