Ethernet Gateway 4 - Accessing local configuration page (HTTP Interface) Locally

If you are attempting to configure your gateway using the local configuration page (HTTP Interface) of an Ethernet Gateway 4 Locally


Note: The Ethernet Gateway 4 has DHCP enabled by default. As there is no default IP address for this gateway (which differs from the Ethernet Gateway 3), it must be connected to a network that supports DHCP in order to first access the local configuration page. In order to do this, you will need to find the IP address that is assigned to the gateway via DHCP from your network. This often requires you to view the IP assignment in your DHCP server (router).

Accessing the local configuration page (HTTP Interface) of an Ethernet Gateway 4.

The Ethernet Gateway 4 offers a local configuration page through which you can modify gateway configurations locally. The page is accessible through a web browser by visiting the gateway’s IP address. The Interface is disabled by default, so it must first be activated to access it. The interface does have an option which will allow you to activate the interface permanently if so desired. This article will provide information on the functionality and steps to access this interface.

Summary of Steps

  • Connect the gateway to a network that supports IP assignment via DHCP.
  • Activate the HTTP Interface (local configuration page).
  • Access the gateway’s local configuration page through a web browser.
  • Configure the gateway.

Connect the gateway to a network that supports IP assignment via DHCP

Connect the gateway to a local Ethernet network that supports DHCP, and power the gateway on. Once the gateway receives an IP address, the bottom LED will go green. This indicates the gateway has a valid IP and local connection to the Ethernet network. You will need to find the IP address that is assigned to the gateway (which might require you to check the IP assignment from the DHCP server). Once you get the IP address, you can enter the IP into a web browser. At this point, the gateway’s local configuration page will not be active (as it is inactive by default for security), so you will see a message that indicates “The interface is currently turned off”. If you see this message, you know you have the correct IP address of the gateway.

Activate the HTTP Interface (local configuration page)

In order to activate the gateway’s HTTP Interface, you will perform the following steps.

  • Power the gateway off.
  • Press and hold the physical Utility button on the gateway.
  • Power the gateway on (continuing to hold the button down).
  • When all three LED’s illuminate and remain solid red, release the button.
  • The gateway’s HTTP Interface (local configuration page) will be active for two minutes.

Access the gateway’s local configuration page through a web browser

If you correctly activated the HTTP Interface, you will see the local configuration page when visiting the IP address of the gateway in a web browser from a computer on the same local network.

Although the interface is activated for 2 minutes, there is a configuration that will allow you to activate the interface longer (permanently if so desired). Many customers operate in such a manner where leaving the interface active is preferable, though the security implications of this should be considered.

To access this configuration:

  • Visit the IP address of the gateway through a browser after activating the HTTP Interface
  • Select the Settings tab
  • Select the Miscellaneous tab
  • You can set the field labeled HTTP Access Timeout (sec) (0=Off 65535=Always On) to a specific timeout value in seconds, or you can enable it permanently by setting this value to 65535 to enable it permanently
  • Select the Save Changes button
  • The gateway will reboot, and the interface will be active with the configured settings

Settings - Miscellaneous

Configure the gateway.

Note: It is worth noting that sensor configurations cannot be modified through the gateway’s HTTP Interface. In order to change sensor configurations, the changes must be made through Monnit software (iMonnit Online, iMonnit Enterprise, iMonnit Express, or a Monnit MINE server). This does mean that customers operating on a private network with the Default Interface disabled will need to configure the sensors with desired settings using Monnit Software prior to disabling the Default Interface.

At this point, you can use the gateway’s local configuration page to modify gateway settings. The most common configuration change that is made, is the assignment of a static IP address. Although, the gateway offers many configurations that can be accessed through the HTTP Interface.

Special Consideration for customers operating with the gateway on a private MODBUS TCP or SNMP network: For customers that are not using the gateway with the Default Interface (iMonnit Online, Enterprise, Express, or MINE), it is worth noting that you can enable/disable the Default Interface through the HTTP Interface. In order to do this, the gateway must be Unlocked. If you are operating with your gateway in this manner, you may see disruptions in the gateway’s operation if the gateway is not Unlocked and the Default Interface disabled.

Conclusion

The Ethernet Gateway 4’s HTTP Interface (local configuration page) allows for dynamic changes to be made to the gateway. If you have any questions regarding the access of the HTTP Interface, feel free to contact Monnit Support.
