5.2 PRODUCT SETUP
Multiple LANS, with Redundancy
The topology in the following figure provides local configuration/monitoring through EnerVista software and access to the
public network shared on LAN1, to which port 1 (P1) is connected. There is no redundancy provided on LAN1. Communica-
tions to SCADA is provided through LAN2. P2 and P3 are connected to LAN2, where P2 is the primary channel and P3 is
the redundant channel. In this configuration, P3 uses the IP and MAC address of P2.
