Initial steps for the troubleshooting/detecting error if NIC card is not detecting on server.
What is NIC(Network interface Card) Card?
A network interface card is a piece of hardware that allows computers to communicate with other devices on a network. It can also be called an Ethernet card, LAN card, or network adaptor. A NIC provides a dedicated connection to a network.
Steps need to follow are mention below:
1: Ensure that the NIC cards are properly seated in the server's PCIe slots. Check is there any physical damage to the NIC cards or connectors.
2: Ensure that the network cables are securely connected to the NIC cards and the network switch. Test the cables and switches with other devices to confirm they are functioning correctly.
3: Access the server's BIOS settings and verify that the PCIe slots are enabled and configured correctly.
4: Make sure that the appropriate drivers for the NIC cards are installed and updated on the server. Check with the vendor for the compatible, updated and latest drivers.
5: Access the Device Manager in operating system to check if the NIC cards are recognized. Check any error messages associated with the NICs.
6: Ensure that the NIC cards are properly configured with IP addresses, subnet masks, and gateway settings if required. Check if there are any IP conflicts with other devices on the network.
7: Try installing the NIC cards in different PCIe slots on the server to rule out any issues with a specific slot.
