Can´t Access Remote Console

PXE (Preboot Execution Environment) boot failure on a Dell server can occur due to a variety of reasons. PXE boot is used to boot a computer over a network, typically to deploy an operating system remotely. Here are some steps you can take to troubleshoot and potentially resolve PXE boot failures on a Dell server:

1. Check Network Connectivity:

   • Ensure that the server is properly connected to the network.
   • Verify that the network cables are securely connected to the appropriate network ports on both the server and the network switch/router.

2. BIOS/UEFI Settings:

   • Access the server's BIOS/UEFI settings during startup (usually by pressing a key like F2, F12, or Delete).
   • Make sure that the server's boot order includes the network boot option (PXE) and that it's set as a higher priority than other boot devices.
   • Check if "PXE Boot" or "Network Boot" is enabled in the BIOS/UEFI settings.

3. DHCP and PXE Server:

   • Ensure that the DHCP server is functioning properly and providing IP addresses to devices on the network.
   • Verify that the PXE server is operational and configured correctly to respond to PXE boot requests.
   • Double-check that the server's MAC address is correctly registered in the PXE server's configuration.

4. Firewall and Security:

   • Check if there are any firewall rules or security settings that might be blocking PXE boot traffic.
   • If the server is in a separate VLAN or subnet, ensure that the necessary routing and firewall rules are in place to allow PXE boot communication.

5. Network Boot File:

   • The PXE boot process requires specific files to be available on the PXE server. Make sure these files are present and correctly configured.
   • Common files include "pxelinux.0" for legacy BIOS boot or "bootx64.efi" for UEFI boot.

6. Network Boot Server Configuration:

   • If you're using a third-party tool to manage PXE boot (e.g., WDS, SCCM), verify that the server's configuration is correct.
   • Ensure that the DHCP options for PXE boot are properly set. DHCP options 66 (Boot Server Host Name) and 67 (Bootfile Name) are commonly used for this purpose.

7. Server Hardware Issues:

   • Check for any hardware issues on the server that might prevent it from successfully completing the PXE boot process. This could include network adapter problems or other hardware failures.

8. Update Firmware and Drivers:

   • Ensure that the server's firmware (BIOS/UEFI) is up to date.
   • Update the network adapter drivers to the latest versions.

9. Diagnostic Logs:

   • Check logs on both the server and the PXE server for any error messages or warnings related to the PXE boot process. This could provide more specific information about the issue.

If you're unable to resolve the PXE boot failure after attempting these steps, it might be helpful to provide a lot more information to start specific troubleshooting and send you resources that can help diagnose and resolve the issue.

I understand that the problem is due to a damage in the OS of the Controller, is there any image or similar to reinstall the system?

Thank you
