There are several ways to configure the monitor for networking. Contact your IT
department or System Administrator to discuss the optimal configuration
method for your network.
Network Security and Firewall Requirements - Ethernet-to-Internet
The monitor sends measurement data to the i-Grid servers over the Internet on
port 80 via the HTTP protocol. The site firewall must allow outbound HTTP
traffic from the IP address assigned to the monitor. This is the same requirement
needed to open a personal computer's web browser and access www.igrid.com.
There are no additional firewall requirements. If a personal computer with an
assigned IP address can access www.igrid.com, then the monitor can use that IP
address as well.
The monitor always initiates the (outbound) connection to the i-Grid servers via
Ethernet to exchange configuration information and upload voltage event data.
The i-Grid servers cannot initiate communication to the i-Sense monitor.
Default Auto-Sensing Configuration - Ethernet
The monitor requires an IP address and related information (see below for
details). The process of assigning an IP address is simplified by an Auto-Sensing
process: The monitor will first attempt to contact a DHCP server for an IP
address. If a DHCP server responds with networking settings, the monitor will
use those settings. If no DHCP server responds, the monitor will fall-back to the
last-used manual (static) networking settings. Once the desired networking
settings are entered, the auto-sensing feature can be disabled.
Even when the network settings will be manually entered (See
Configuration - Ethernet or Direct Connection to a Personal Computer on
page
11), the monitor can be temporarily connected to a network that supports
DHCP to more easily acquire those settings. The desired static IP address can
then be entered prior to installation.
To connect your web browser to the i-Sense Management Console over the local
network, the monitor IP address must be known. And if you are using DHCP,
the IP address might not be evident.
