Description

OPAL-RT performs the initial OS installation and configures a default IP address, which you can find on a sticker located at the front of your simulator. In many cases, you will need to reconfigure this IP address to integrate the simulator into your network. This procedure provides step-by-step instructions to adjust the simulator’s IP address to meet your network requirements. To connect a host computer directly to the simulator, without changing the simulator IP address, see this KB article.

OP4512, OP5020XG, OP5033XG, OP5705XG, and OP5707XG Simulators

Prerequisites

• Equipment: Connect a monitor to the simulator’s VGA port, a keyboard to any USB port, an Ethernet cable to LAN1, and a power cable.

• Applicable Systems: OP4512, OP5020XG, OP5033XG, OP5705XG, OP5707XG.

• Network Configuration: Consult your IT department to determine if a static IP address can be assigned to the simulator on the network. They will likely provide a range of IP addresses that your Windows host computer can communicate with.

For configuring an OP4610XG or an OP5025XG simulator, please go to the following section entitled OP4610XG and OP5025XG Simulators.

Open

OP4512, OP5020XG computer ports

Open

OP5033XG, OP5705XG, OP5707XG computer ports

Configure the IP Address

1. Power On the System

• Turn on the main power switch at the back of the simulator.

• Press the power button on the front panel.

2. Log in to OPAL-RTLinux

• You’ll see the OPAL-RTLinux login prompt.

• Enter the following credentials:

  • Username: root

  • Password: Refer to the System Description Document provided with your hardware. You can find this document on the CD or USB drive that was shipped with your system package. If you cannot find the login credentials, contact OPAL-RT Technical Support.

After a successful login, you should see the OPAL-RTLinux prompt as shown below:

3. Check the Current IP Address

• To verify the current IP, type the following command:

  ip a

  The output should display network interfaces and their IP addresses. Note that eno1 corresponds to the LAN1 Ethernet port and eno2 to the LAN2 Ethernet port.
  
  

• If you cannot run the commands, contact OPAL-RT Technical Support.

4. Configure a Static IP Address

• Run the network configurator:

  opal_network_configurator

• Read and follow the prompts. Type yes and press Enter to proceed.
  
  

• Read or skip the IPMI Information section and the Oregano Card section. Then read and follow the prompts of the Setting Up Network Interfaces section. The script will list the Network interfaces one by one, staring with eno1.

  • To configure a new static IP address for eno1, type the desired IP address including the netmask: xxx.xxx.xxx.xxx/xx and press Enter. For example, to set the IP 10.64.110.204 with a /19 netmask (optional, default: 255.255.224.0), type 10.64.110.204/19 and press Enter. Note that the IP address must be unique on your network.

  • To configure eno1 to DHCP, type dhcp and press Enter. OPAL-RT software needs to know the simulator IP address to run models. Therefore, DHCP mode is not recommended.

  • To keep the IP address of eno1 intact and skip to the next network interface, do not type in the command prompt and only press Enter.
    
    

• Press Enter to skip the configuration of subsequent network interfaces until the network restarts.
  
  

• You can also decide to configure the other network interfaces. To do so, read and follow the prompts the same way as for eno1.

5. Verify the New IP Address

• To verify the new IP address, type ip a and validate the IP address.

3. Check the Current IP Address

• To verify the current IP, type the following command:

  ip a

  The output should display network interfaces and their IP addresses. Note that enp39s0corresponds to the LAN1 Ethernet port, enp38s0to LAN2 Ethernet port, enp36s0f0 to LAN3 Ethernet port and enp36s0f1 to LAN4 Ethernet port.
  
  

• If you cannot run the commands, contact OPAL-RT Technical Support.

4. Configure a Static IP Address

• Run the network configurator:

  opal_network_configurator

• Read and follow the prompts. Type yes and press Enter to proceed.
  
  

• Read or skip the IPMI Information section and the Oregano Card section. Then read and follow the prompts of the Setting Up Network Interfaces section. The script will list the Network interfaces one by one, staring with enp39s0.

  • To configure a new static IP address for enp39s0, type the desired IP address including the netmask: xxx.xxx.xxx.xxx/xx and press Enter. For example, to set the IP 192.168.3.97 with a /19 netmask (optional, default: 255.255.224.0), type 192.168.3.97/19 and press Enter.

  • To configure enp39s0 to DHCP, type dhcp and press Enter. OPAL-RT software needs to know the simulator IP address to run models. Therefore, DHCP mode is not recommended.

  • To keep the IP address of enp39s0 intact and skip to the next network interface, do not type in the command prompt and only press Enter.
    
    

• Press Enter to skip the configuration of subsequent network interfaces until the network restarts.
  
  

• You can also decide to configure the other network interfaces. To do so, read and follow the prompts the same way as for enp39s0.
