OEMR XL R640 - A fatal error was detected on a component at bus 23 device 2 function 0 and The NDC is absent.

Hi,

The error messages you provided indicate that there are issues with certain components in your Dell EMC PowerEdge R640 server. Let's break down the messages:

1. A fatal error was detected on a component at bus 23 device 2 function 0.
2. A fatal error was detected on a component at bus 25 device 0 function 0.
3. A problem was detected during Power-On Self-Test (POST).
4. The NDC is absent.

Here's a general analysis:

• Fatal errors on components: The messages suggest that there are fatal errors on components at specific locations on the system bus. This could indicate a hardware failure in those particular components. It might be related to a malfunctioning device or peripheral.
• Power-On Self-Test (POST) issue: The system detected a problem during the Power-On Self-Test. This is the diagnostic process performed by the system firmware when the server is powered on. Failures during POST could be due to hardware issues.
• The NDC is absent: The NDC stands for Network Daughter Card. This message suggests that the network interface card is not present or not functioning properly. This could be a separate issue or related to the other errors.

To troubleshoot and resolve the issue:

1. Check Hardware Connections: Ensure that all components are properly connected and seated in their respective slots.

2. Reseat Components: Try reseating the components mentioned in the error messages. Turn off the server, unplug it, and then carefully reseat the components.

3. Check Network Daughter Card (NDC): If the NDC is absent, check whether it's physically connected and properly seated. If it's a separate card, consider reseating it or replacing it if necessary.

4. Update Firmware/BIOS: Check if there are any firmware or BIOS updates available for your server model. Applying updates might resolve compatibility or stability issues.

5. Review System Logs: Check other system logs and management tools for more detailed error messages or information that might help pinpoint the issue. 

Probably a hardware replacement is needed.
