You can add a LON IP-852 router to the SmartServer.  You will typically use an IP-852 router if your installation has a LON IP-852 channel.  The LON IP-852 standard requires use of an IP-852 Configuration Server to monitor and configure the IP-852 routers and clients.

This section consists of the following:

LON IP-852 Router Implementation Overview

The SmartServer IP-852 Router can be used in the following two ways:

1. As a self-installed IP-852 router. This method allows you to create an IP-852 network with two or more SmartServer IoTs without using a network integration tool to add the SmartServers to the network (similar to the i.LON 600 "Self-install router as repeater" feature). This method is useful when a network integration tool does not know how to use routers. In this case, the IP-852 network is separate from the device network.
   
   This method can only be used if you are using the SmartServer IoT for IP-852 routing. That is, this method cannot be used if you want to use the SmartServer for monitoring, controlling, logging, alarming, or scheduling of the devices' datapoints.
   
   A self-installed IP-852 router is used as a repeater and all traffic on one LonWorks channel (e.g., TP/FT-10) is sent to all other channels. Since many LonWorks channels are half-duplex, you need to make sure that traffic on one channel does not drastically affect bandwidth on all channels.
   
   See the steps described in installation example 1 for more information about setting up self-installed IP-852 routers.
   
   

2. With a network integration tool (e.g., IzoT CT and IzoT Net Server). This method requires you to add the SmartServer IP-852 routers to an IzoT Net Server network using a network integration tool (e.g., IzoT CT).
   
   See the steps described in installation example 2 for more information about setting up IP-852 routers with a network integration tool.

Configuring the IP-852 Feature

To use the IP-852 feature, you must:

• Enable the SmartServer IoT to support IP-852

• Define devices on the IP-852 channel using the IP-852 Configuration Server application

• Define a VNI interface in the LonWorks Interfaces (32-bit) control panel applet

The procedure that follows provides the necessary steps to enable and define IP-852 devices, beginning with the IzoT CT design and ending with commissioning devices.

Setting up IP-852 Routing in IzoT CT 

1. Begin with a new project in IzoT CT, working in engineering mode. For information about IzoT CT, see the IzoT CT and OpenLNS CT page.
   
   

2. Define the first channel to be an IP-852 backbone by name and defined characteristics.
   

   
   
   

3. Create additional elements in IzoT CT to complete the network design, such as:

   1. Add channels and a router per USB adapter that is connected to the SmartServer's four-port USB hub.

   2. Add a router between the IP-852 channel and the internal IP-70 channel.

   3. Add LON FT channels connected by a logical IP-852 channel over the local IPv4 infrastructure.

   4. Add a device on each FT segment as needed for routing over the IP-852 channel.

Continue setting up the IP-852 feature following the steps in the section below: Enabling IP-852 in the SmartServer IoT Configuration Pages. 

Enabling IP-852 in the SmartServer IoT Configuration Pages

1. Log into the SmartServer configuration UI with the username and password.
   

   
   
   

2. Click OK to login as appropriate for your web browser.
   
   The Network Configuration page appears.
   

   
   
   

3. Click the LON tab.
   
   The LON Configuration page appears.
   

   
   
   

4. Enable the Interface → eth0 option and click Update.
   
   

   
   
   

5. Enable the IP-852 feature as described above for each SmartServer in the system.

Continue setting up the IP-852 feature following the steps in the section below: Defining the IP-852 Channel Devices. 

Switching to LON Independent Management Mode (IMM)

LON Device Management Mode (DMM) is the default SmartServer IoT setting where the SmartServer managed the configuration of all the LON devices provisioned by the SmartServer.

Since IzoT CT is used as the network management tool to manage the network configuration of the LON devices, this setting must be changed to LON Independent Management Mode (IMM), where the SmartServer acts as an independent device in the LON network. The steps below describe how to change this setting from LON DMM to LON IMM using the SmartServer CMS. 

1. Log into the SmartServer CMS in one of the following ways:

   1. From the SmartServer Configuration UI: CMS tab.
      
      If you still have the LON Configuration page opened from the steps above, then click the CMS tab.
      

      
      
      

   2. From a web browser URL: Open the SmartServer IoT CMS.
      
      

2. Go to the SmartServer CMS Devices widget and select the Switch to LON Independent Management Mode action.
   
   See Switching LON Management Mode for more information.
