NVIDIA NVLink SGXLS10 Switch Systems User Manual

The systems support the following interfaces:

  • Data interfaces -

  • 10/100/1000Mb Ethernet management interface (RJ45)

  • USB port (USB Type A)

  • RS232 Console port (RJ45)

  • Reset button

  • Lane Select button and LEDs*

  • Status and port LEDs

*In the NVLink switch systems, the Lane Select option is disabled. Thus, the Lane Select button and LEDs are non-functional.

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

The data interfaces use OSFP connectors. The full list of interfaces per system is provided in Speed and Switching Capabilities.

Each OSFP port consists of four logical ports, and can be connected with OSFP cable or connector for 128 ports of 212.5Gb/s. The system offers High Power class 8 transceivers support in all ports.


The system is based on two NVlink4 (LS10) ASICs, and provides up to 128x200Gb/s (NVLink4) full bandwidth bidirectional ports.


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 to view the full procedure.


The RJ45 Ethernet “MGT” port is labeled



The Management RJ45 Ethernet ports provide access for remote management. The management ports are configured with auto-negotiation capabilities by default (100MbE to 1GbE). 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 to view the full procedure.


Make sure you use only FCC compliant Ethernet cables.

The USB interface is USB3.0 type A compliant and can be used by the NVOS software to connect to an external disk for software upgrade or file management. The connector comes in a standard micro USB shape. To view the full matrix of micro 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.

The reset button is located on the front side of the system under the USB port. 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.

  • To reset the system, push the reset button for less than 15 seconds.

  • When using an NVOS 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 enter without a password and set a new password for the user “admin”.

The Lane Select button is located on the front left side of the system under the Lane Select LEDs. This button is non-functional and should not be used.
