Ethernet Communications
Setup There are several ways to configure the i-Sense 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 i-Sense 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 i-Sense. This is the same requirement
needed to open a PC’s Web browser and access www.igrid.com. There are no
additional firewall requirements. If a PC with an assigned IP address can access
www.igrid.com, then the i-Sense can use that IP address as well.
The i-Sense always initiates the (outbound) connection to the i-Grid servers via
Ethernet or modem 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 i-Sense 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 i-Sense will first attempt to contact a DHCP server for an IP address. If a
DHCP server responds with networking settings, the i-Sense will use those
settings. If no DHCP server responds, the i-Sense 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 (Refer to Manual
Configuration - Ethernet or direct connection to a PC on page 8 ), the i-Sense 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 i-Sense IP address must be known. And if you are using DHCP, the
IP address might not be evident.
