Prepare the System for Replacement#

Usually, a network interface card fails to function for the following reasons:

  • The operating system does not detect the device.

  • The device does not transmit or receive data.

After you rule out external connectivity issues, contact NVIDIA Enterprise Support to receive a replacement card.

When you receive the card, begin the replacement by performing the following actions:

  1. Power off the system.

  2. Open the motherboard tray I/O door to access the rear section of the motherboard. Refer to Motherboard Tray - Opening and Closing the I/O Door for more information.

Remove the Non-Functional Card#

First, turn the locking mechanism 90 degrees so the card can be extracted from the PCI slot:

  1. Confirm the motherboard tray service lid is open and loosen the thumbscrew for the PCI card locking mechanism next to slots 1 and 3:
