ABSTRACT:
A power meter or other electrical device is provided having two independent and communicatively isolated Ethernet ports. The first Ethernet port is addressable by a first unique identifier and is configured for enabling full access to the power meter via an internal LAN. This enables a LAN operator to remotely access the power meter via the internal LAN for performing metering functions, such as full telemetry, control and programming. The second Ethernet port is addressable by a second unique identifier and is configured for being connected to the Internet. Since the second Ethernet port is communicatively isolated from the first Ethernet port, a user can access the power meter via the Internet, but cannot access the internal LAN by connecting to the power meter via the Internet.
