Figure 1. Back side of the NVIDIA IGX Orin Developer Kit
Below are the Minimal IGX Orin Developer Kit hardware connections required to set up BMC, and get BMC access over Ethernet.
2 – Power switch
3 – Power cable connection
5 – 1GbE RJ45 connection for BMC
8 – DisplayPort output from Orin
9 – USB 3.2 Gen2 Type C connector
All the other numbering you can check in the NVIDIA IGX Orin Developer Kit User Guide
Powering Up the System
Connect the peripherals listed above to the system before powering up.
Connect the power cable to the system.
Turn on the Power Switch.
Host Setup for BMC
Connect your Ubuntu host machine and the developer kit with an Ethernet cable. Make sure it’s port 5, the right side of one of the two Ethernet ports.
Find out which Ethernet adapter on the host machine is connected, then start static IP configuration.
Configure the remote Ubuntu host machine Ethernet adapter as a static node. Thus, the Ubuntu Host can communicate to the BMC over the static IP address
192.168.1.110.Find the network adapter in
ifconfig, which is connected to the RJ45 port of the NVIDIA IGX Orin Developer Kit, then configure it as a static route. The name can beem1oreno1or whatever you choose. As an example:ifconfig eno1 192.168.1.1 netmask 255.255.255.0Test the connection to the BMC default IP address with either an SSH or ping.
If the host fails to communicate with BMC, then follow the steps in Configuring Ubuntu as a DHCP Host. Otherwise, skip to Accessing BMC over SSH.
Configuring Ubuntu as a DHCP Host (Optional)
Install DHCP server.
sudo apt-get update sudo apt-get install isc-dhcp-server
Edit the DHCP config file /etc/dhcp/dhcpd.conf as per below.
Add a block to the end of the file:
subnet 192.168.1.0 netmask 255.255.255.0 { range 192.168.1.100 192.168.1.200; option routers 192.168.1.1; option broadcast-address 192.168.1.255; }
Subnet – This can be another logical IP gateway as well.
Range – The available IP pool; the client can have an IP address only in this range.
Router IP Address – This is the IP address of the Ubuntu host.
Now, set the Ubuntu wired network interface (which is connected to BMC) static IP like the router address.
The wired network interface name depends on the host. It can be
em1/eno1or anything else you choose.
ifconfig eno1 192.168.1.1 netmask 255.255.255.0
Restart the DHCP server.
sudo systemctl restart isc-dhcp-server
Ping BMC
ping 192.168.1.110
Switch to Static DHCP Mode
You can switch the DHCP IP mode in BMC using IPMI tool, and you can find the BMC IP address in the DHCP server lease list against known BMC MAC address
The inbound command is:
ipmitool lan set 1 ipsrc dhcp
Alternatively, you can use the OOB command over ethernet.
ipmitool -C 17 -I lanplus -U <BMC user> -P <BMC Password> -H
192.168.1.110 lan set 1 ipsrc dhcp
BMC will switch mode to DHCP quickly after the execution of the above command and will search for the DHCP lease IP. If the Ubuntu host is configured as a DHCP server, you can find BMC IP in lease-list using the following command:
dhcp-lease-list
You can also connect BMC to the network, and you can search BMC IP in the router lease list against the MAC address.
To configure BMC back to a static IP address, refer to the table in Available Network IPMI Commands.
Accessing BMC over SSH
For the first time logging in, you will be prompted to change the password: add default password “0penBmc (here, the first character is '0' zero)”
Next, set the new password with uppercase, lowercase, special and number characters included. For example, the new password could be Bmc@123.
ssh root@192.168.1.110
password: 0penBmc
You are required to change your password immediately (administrator enforced)
Changing password for root.
Current password: 0penBmc
New password: Bmc@123
Retype new password: Bmc@123
