Network Topologies - GE DuraStation Operation And Maintenance

DuraStation™ EV Charger User Manual

5.3 Network Topologies

There are many different network topologies that the GE DuraStation supports. This includes wired
Ethernet, WiFi and a dedicated Cellular modem. It is important to understand the following minimum
requirements for all topologies.
- Internet connection ... either Ethernet, WiFi or cellular
- LAN switch or WiFi Access Point
- DHCP server or a Static IP Address
- Wired Ethernet – Cat5 or better wiring
- WiFi Access Point that supports 802.11 b/g WiFi speeds
Please note that the pictorials shown below are of the WattStation™ Wallmount. Note that
dual charge port stations only have one single board computer thus only 1 cable needs to be
run, so from a networking perspective DuraStations™ are the same.
Topology #1: Ethernet
In this configuration each DuraStation is connected to a common Ethernet LAN to provide
primary connectivity. The DuraStations do not need to be plugged into the same switch, but
the switches must be part of the same common network segment or VLAN. Internet
connectivity is provided through the default gateway.
Topology #2: WiFi
In this configuration the unit's WiFi port is used to provide primary connectivity. The security
settings for the WiFi must be manually configured in the DuraStation before connectivity can
take place.
