1.1 Access the IG902

• Step 1: By default, the IP address of GE 0/1 on IG902 is 192.168.1.1; the IP address of GE 0/2 on IG902 is 192.168.2.1. This document uses the GE 0/2 port to access the IG902 as an example. Set the PC’s IP address to be on the same subnet with GE 0/2.

  • Method 1: Enable the PC to obtain an IP address automatically (recommended)

    

  • Method 2: Set a fixed IP address

    Select Use the following IP address, enter an IP address (By default,any from 192.168.2.2 to 192.168.2.254), subnet mask (By default,255.255.255.0), default gateway (By default,192.168.2.1), and DNS server address, and click OK.

    

• Step 2: Launch the browser on the PC and access the IP address of GE 0/2. Enter the login user name and password. The default user name and password are adm and 123456 respectively.

  

• Step 3: After successful login, you can see the web page as shown below:

  

• Step 4: To change the user name and password for logging in to the web management interface of IG902, choose System > User Management page of IG902 and set the new user name and password.

  

• Step 5: To change the IP address of GE 0/2, choose Network > Network Interfaces > Ethernet > Gigabitethernet 0/2 page of IG902 to configure GE 0/2.

  

1.2 Connect IG902 to the Internet

• Method 1: Connect to the Internet by SIM card

  • Step 1: Insert the SIM card. (Note: Before inserting or removing the SIM card, unplug the power cable; otherwise, the operation may cause data loss or damage the IG902.) After inserting the SIM card, connect the 4G LTE antenna to the ANT interface and power on the IG902.

    

  • Step 2: Choose Network > Network Interfaces > Cellular page of IG902 and select Enable Cellular and click Submit.

    

    When the network connection status is Connected and an IP address has been allocated, the IG902 has been connected to the Internet with the SIM card.

    

• Method 2: Connect to the Internet by Ethernet

  • Step 1: Use the Ethernet cable to connect the GE 0/1 and GE 0/2 ports of the IG902 respectively, as shown below:

    

  • Step 2: Choose Network > Network Interface > Ethernet > Gigabit Ethernet 0/1 page of IG902 to configure the IP address of the GE 0/1 port and click Submit. (When the network type is a static IP address, you need to configure the IP, subnet mask, and other information according to the site network conditions.)

    

    

  • Step 3: Choose Network > Static Routing > Configuration page of IG902 to add a static route for GE 0/1 port and click Submit. (Select “Gigabitethernet 0/1” for the interface item, and configure the other items according to the site network conditions.)

    

  • Step 4: Choose System > Network Tools page of IG902 and use the Ping tool to check whether the IG902 has successfully connected to the Internet. The following figure shows that IG902 have successfully connected to the Internet:

    

3.1 Install and run Python App

To install and run Python App (App for short) in IG902, please refer to the following process:

• Step 1: Install the App

  Before installing the App, you need to ensure that the Python Edge Computing Engine is enabled and the Python SDK is installed, as shown in the following figure:

  

  Choose Edge Computing > Python Edge Computing. click the Add button and select the App package file to be installed, then click OK.

  

  After importing, you can view the imported Apps, as shown in the following figure:

  

• Step 2: Run the App

  Select enable App and click Submit.

  

  Once enabled, the App automatically runs and will run every time the IG902 is started.

  

3.2 Update Configuration File for App

If the installed App supports importing configuration files to modify the running mode, you can update the App running configuration by referring to the following process:

• Step 1: Choose Edge Computing > Python Edge Computing, click the Import Configuration button and select the configuration file to be imported, then click Confirm.

  

• Step 2: Restart the App after the import is successful. After the App restarts, it will runing according to the imported configuration file.

  

3.3 Update Python App version

Generally, if you need to update the Python App version, you only need to import the new version of the App on the Edge Computing > Python Edge Computing page.

After the update is completed, as shown below：

3.4 Enable the Debug Mode

To run and debug Python code on IG902, you need to enable IG902’s debug mode. Choose Edge Computing > Python Edge Computing, select Enable Debug Mode. After enabling, you can develop IG902 through VS Code. How to use VS Code for Python development of IG902, please refer to Quick Start for MobiusPi Python Development.

After the debugging mode is enabled, IG902 will start an SSH server to listen on port 222 of LAN (default IP address being 192.168.2.1). The user name and password of the SSH server are displayed on the previous web page. A random password is generated every time the debugging mode is enabled or the IG902 is restarted to ensure security.

Factory reset

There are two ways to restore the IG902 to factory settings: hardware factory reset and software factory reset.

• Hardware factory reset

  • Step 1: After the device is powered on and the ERR light is off, press and hold the RESET key;
  • Step 2: When the ERR light is always on, release the RESET key;
  • Step 3: After the ERR light goes out, press and hold the RESET key again, and release the RESET key when the ERR light flashes; wait for the ERR light to go out, indicating that the factory reset was successful.

• Software factory reset

  Choose System Management > Configuration Management, click the reset button and select OK. IG902 will complete the factory reset operation by itself.
