The systems support the following interfaces:

  • 10/100/1000Mb Ethernet management interface (RJ45) 
  • USB port (Type A or uUSB connector) 
  • RS232 Console port (RJ45)
  • Reset button 
  • Status and Port LEDs

In order to review the full configuration options matrix, refer to Management Interfaces, PSUs and Fans.

Data Interfaces

The data interfaces use QSFP28/56/DD connectors. The full list of interfaces per system is provided in Speed and Switching Capabilities.

As detailed in the following table, for additional data interfaces, each QSFP28/56/DD port can be connected with a QSFP28/56/DD cable or connector through NVIDIA QSFP28/56/DD to SFP (Dynamix QSA™) adapters, hybrid or split cables*.

*In the SN4600, SN4700 and SN4410 systems, when interconnecting Switch to Switch and Switch to NIC in 50GbE, 100GbE 200GbE and 400GbE based PAM4 speeds, the supported length of PAM4 passive copper and breakout cables is up to 2.5m. 


The systems offer several high-power ports for optical transceivers that require such support. The following table specifies each system's ports max power capabilities:

Speed

Ethernet speed must be set manually. The system’s ports can be manually configured to run at speeds ranging from 1GbE to 200GbE/400GbE (for more details, see Specifications). To change the port speed configuration, use the command “speed” under interface configuration mode. Refer to the NVIDIA Onyx (MLNX-OS) User Manual for instructions on port speed re-configuration.

RS232 (Console)

The RS232 serial “Console” port is labeled .

The “Console” port is an RS232 serial port on the front side of the chassis that is used for initial configuration and debugging. Upon first installation of the system, you need to connect a PC to this interface and configure network parameters for remote connections. Refer to Configuring Network Attributes Using NVIDIA Onyx (MLNX-OS) to view the full procedure.

Management

The RJ45 Ethernet “MGT” port is labeled .

The RJ45 Ethernet “MGT” port provides access for remote management. The management ports are configured with auto-negotiation capabilities by default (10MbE to 1000GbE). The management ports’ network attributes (such as IP address) need to be pre-configured via the RS232 serial console port or by DHCP before use. Refer to Configuring Network Attributes Using NVIDIA Onyx (MLNX-OS) to view the full procedure.

Make sure you use only FCC compliant Ethernet cables.

USB

The USB interface is USB 2.0 compliant and can be used by NVIDIA Onyx software to connect to an external disk for software upgrade or file management. The connector complies with the USB 3.0 type A standard.

To view the full matrix of the USB configuration options, refer to Management Interfaces, PSUs and Fans.

USB 1.0 is not supported.
Do not use excessive force when inserting or extracting the USB disk to and from the connector.

Reset Button

The reset button is located on the front side of the system. This reset button requires a tool to be pressed.

Do not use a sharp pointed object such as a needle or a push pin for pressing the reset button. Use a flat object to push the reset button.

When using an NVIDIA Onyx (MLNX-OS) based system, keeping the reset button pressed for more than 15 seconds will reset the system and the “admin” password, this should allow you to login without a password and set a new password for the “admin” user.

For Cumulus Linux password reset instructions, please refer to the Single User Mode - Boot Recovery section in the Cumulus Linux User Guide.
