Connecting to DGX H100/H200#

Connecting to the Console#

Connect to the DGX H100/H200 console using either a direct connection or a remote connection through the BMC.

Important

Connect directly to the DGX H100/H200 console if the NVIDIA DGX™ H100/H200 system is connected to a 172.17.xx.xx subnet.

DGX OS Server software installs Docker Engine which uses the 172.17.xx.xx subnet by default for Docker containers. If the DGX H100/H200 system is on the same subnet, you will not be able to establish a network connection to the DGX H100/H200 system.

Refer to Configuring Docker IP Addresses in the NVIDIA DGX OS 6 User Guide for instructions on how to change the default Docker network settings.

Direct Connection#

At the front or the back of the system, you can connect a display to the VGA connector and a keyboard to any of the USB ports.

The system provides video to one of the two VGA ports at a time. Simultaneous video output is not supported. If you connect two both VGA ports, the VGA port on the rear has precedence.

Note

The display resolution must be 1440x900 or lower.

Remote Connection through the BMC#

Here is some information about how you can remotely connect to DGX H100/H200 through the BMC.

NVIDIA recommends that customers follow best security practices for BMC management (IPMI port). These include, but are not limited to, such measures as:

  • Restricting the DGX H100/H200 IPMI port to an isolated, dedicated management network.

  • Using a separate, firewalled subnet.

  • Configuring a separate VLAN for BMC traffic if a dedicated network is not available.

This method requires that you have the BMC login credentials. These credentials depend on the following conditions:

Before the First Boot Setup

Caution

You perform the First Boot Setup to change the default credentials before connecting the BMC to an unsecured network.

  • The default credentials are:

    • Username: admin

    • Password: admin

Caution

When you create a BMC admin user, we strongly recommend that you change the default password for this user - DO NOT use the default password.

After the First Boot Setup

During the first-boot procedure, you were prompted to configure an administrator username and password and a password for the BMC. The BMC username is the same as the administrator username:

  • Username: <administrator-username>

  • Password: <bmc-password>

  1. Make sure you have connected the BMC port on the DGX H100/H200 system to your LAN.

  2. Open a browser within your LAN and go to https://<bmc-ip-address>/

    Make sure popups are allowed for the BMC address.

  3. Log in.

  4. From the navigation menu, click Remote Control.

    The Remote Control page enables you to open a virtual Keyboard/Video/Mouse (KVM) on the DGX H100/H200 system, as if you were using a physical monitor and keyboard connected to the front of the system.

  5. Click Launch KVM.

    The DGX H100/H200 console appears in your browser.

SSH Connection to the OS#

After the system has been configured, you can also establish an SSH connection to the DGX H100/H200 OS through the network port. Refer to Network Ports to identify the port to use.
