Cable Installation

NVIDIA NVLink SGXLS10 Switch Systems User Manual

In some switch models, the product's package includes cable retainers. It is highly recommended to use them in order to secure the power cables in place.

When installing retainers for the PSUs of the switch systems, please adhere to the following instructions:

  1. Verify the integrity of the retainer assembly, as demonstrated in the below table:- The snaps' push-pins must have visible edges with no broken or torn parts.
    - The shoulders' pins should be in-tact and must not be bent inwards.

  2. It is advised to place the PSU on a flat, stable surface. While you secure the PSU in place, use two thumbs to insert the retainer's two snaps into the designated holes located near the AC inlet. Make sure that the retainer's plastic loop is facing upwards, as demonstrated in the below table.


    For demonstration purposes, the images in this document show C2P (Connector-to-Power) airflow PSUs with red latches, yet the instructions apply to P2C (Power-to-Connector) PSUs with blue latches as well.

  3. Push the retainer until the shoulders' pins (in blue circles below) are open and aligned with the PSU front panel, as shown in the following table:

  4. Make sure that the retainer is fully locked in place by gently attempting to pull it outwards.

  5. Open the plastic loop and route the AC cord through it. Locate the loop over the AC cord, as shown in the following table, and fasten it tightly.

    Proper Loop Placement

Each cable retainer can be used once only. Once the retainer has been fully inserted and the shoulders' pins have been adjusted, the retainer cannot be used again, and should be discarded if pulled out.

All cables can be inserted or removed with the unit powered on.

To insert a cable, press the connector into the port receptacle until the connector is firmly seated. The LED indicator, corresponding to each data port, will light when the physical connection is established. When a logical connection is made, the relevant port LED will turn on.

To remove a cable, disengage the locks and slowly pull the connector away from the port receptacle. The LED indicator for that port will turn off when the cable is unseated.

For full cabling guidelines, please refer to the NVIDIA Cable Management Guidelines and FAQs Application Note.

For more information about port LEDs, refer to Port LEDs.


Do not force the cable into the cage with more than 40 newtons/9.0 pounds/4kg force. Greater insertion force may cause damage to the cable or to the cage.


Unused OSFP cages must be closed with the dust caps supplied with the system.
