Any firewall used for a DMZ environment should be a business class system (i.e. Cisco ASA,
Checkpoint, SonicWall, etc) and provide a true DMZ capability. Typical SOHO firewalls do NOT
provide true DMZ capabilities.
GE supports the use of the Cisco ASA5505 firewall and provides settings for its use in this scenario.
o Physical Security.
Physical security is a necessary consideration in any installation of this type. There should be
physical controls to reduce the probability of a malicious entity’s chances of gaining access to any
area of the system.
Network, maintenance access and power connections should be secured with strong physical
controls, i.e. all connections behind an access panel or door with a keyed lock to limit access. This
door or access panel should be strong (metal as a suggestion) and the lock should be of a type that
is not commonly available to the general public.
All wiring should be enclosed in conduit meeting the local electrical and communications building
codes. And all conduits should firmly attach to the secured “box” where communications would be
terminated within the Charging Station.
4.3 Controller Configuration
4.3.1 Introduction
The Configuration Server Interface is used to make modifications to the network settings and to
certain operation parameters of the charging station controller. The controller will boot into a default
configuration. The network defaults will need to be changed in order to accommodate the decisions
in choosing the stand-alone or fire-walled configuration and to avoid conflicts with the installation of
subsequent controllers.
Each EVSE needs to be configured individually using a service PC or laptop during the installation and
setup of the controllers.
4.3.2 Prepare Service Laptop or PC
In order to set up your service laptop or PC, make sure you have full Windows Administrator rights.
Disable any firewalls and all other Ethernet and WiFi connections for the duration of the setup.
Make sure no EVSE is connected or at least not powered during these setup changes.
Then follow these steps to configure your TCP/IP settings for communication with the EVSE during
setup.
After the setup, you may want to set them back to your normal settings by undoing the same steps,
enable WiFi connections and firewalls.
1. Open the network settings by going to Start > Control Panel > Network connections.
