Appendix D: SiteSage Networking Requirements
SiteSage Controllers and Energy Monitor units communicate via a wireless radio to the SiteSage
Gateway. The radios have a range of at least 30 feet and do not require line of sight. The
Gateway needs to be connected to a facility network in order to access the Internet to upload
data to the SiteSage cloud-based servers. Depending upon the location of the electrical panels,
it is conceivable that there will need to be more than one Gateway installed.
The SiteSage Gateway is a “headless” device which can be connected through hardwired
Ethernet or Wi-Fi (B or G only). It only requires Port 80 to be open, and only makes
outgoing
HTTP requests to the SiteSage servers. There is no way to communicate with the Gateway from
the Internet, other than through the responses to the HTTP request.
Ethernet Connection
(the clear preference is to use Ethernet wherever possible in order to
maximize reliability).
Normally
,
the SiteSage Gateway requires DHCP in order to connect to the network. If DHCP is
not used in the facility, a static IP address can be provisioned, but the Gateway must first be
attached to the network using DHCP. If a DHCP server is not available in the facility, it is
possible to provision the system on another network that has DHCP and then move it to the
destination network. The system can connect to an HTTP proxy server; to configure for a proxy
server we will need to know the IP address or URL and port number.
If a static IP address is required, we will need to know, in advance, the following information:
IP Address
Network Mask
Gateway IP Address
DNS Server IP Address
DNS Server2 IP Address (Optional)
If MAC level filtering is enabled on the network we can provide the Ethernet MAC address in
advance, if required. If there is a restriction to a specific port, we will need to know which port
on the switch to attach to. (In the event that the Gateway is not connecting directly to the
switch, we will need to coordinate on the installation).
Wi-Fi Connection
If Wi-Fi is required, the preference is a secured connection. The Gateway needs to be
connected to a network that is up 24 X 7 and does not limit users’ connection time. Because
the system is headless, there is no way to accept terms or respond to a prompt. If the standard
public network in the facility has any such restrictions that can be overridden, the Wi-Fi MAC
address can be provided in advance to allow the system to be pre-provisioned.
