Use this information to recover the server firmware and restore the server operation to the primary bank.

1. Read the safety information that begins on page Safety and Handling static-sensitive devices.
2. Turn off the server, and disconnect all power cords and external cables.
3. Remove the server cover. See Removing the cover for more information.
4. Locate the UEFI boot recovery jumper block (J29) on the system board.

5. Remove any adapters that impede access to the UEFI boot recovery jumper block (J29), see Removing an adapter.
6. Move the jumper from pins 1 and 2 to pins 2 and 3 to enable the UEFI recovery mode.
7. Reinstall any adapter that you removed before (see Replacing an adapter).
8. Reinstall the server cover (see Installing the cover); then, reconnect all power cords.
9. Restart the server. The power-on self-test (POST) starts.
10. Boot the server to an operating system that is supported by the firmware update package that you downloaded.
11. Perform the firmware update by following the instructions that are in the firmware update package readme file.
12. Copy the downloaded firmware update package into a directory.
13. From a command line, type filename-s, where filename is the name of the executable file that you downloaded with the firmware update package. Monitor the firmware update until completion.
14. Turn off the server and disconnect all power cords and external cables, and then remove the server cover (see Removing the cover).
15. Remove any adapters that impede access to the UEFI boot recovery jumper block (J29) (see Replacing an adapter).
16. Move the UEFI boot recovery jumper from pins 2 and 3 back to the primary position (pins 1 and 2).
17. Reinstall any adapter that you removed before (see Replacing an adapter).
18. Reinstall the server cover (see Installing the cover); then, reconnect all power cords.
19. Restart the server. The power-on self-test (POST) starts. If this does not recover the primary bank, continue with the following steps.
20. Remove the server cover (see Removing the cover).
21. Reset the CMOS by removing the system battery (see Removing the system battery).
22. Leave the system battery out of the server for approximately 5 to 15 minutes.
23. Reinstall the system battery (see Installing the system battery).
24. Reinstall the server cover (see Installing the cover); then, reconnect all power cords.
25. Restart the server. The power-on self-test (POST) starts.
26. If these recovery efforts fail, contact your IBM service representative for support.
