In-band manual recovery method
This section details the in-band manual recovery method.
To recover the server firmware and restore the server operation to the primary bank, complete the following steps:
- Read the safety information that begins on Safety and Installation guidelines.
- Turn off the server, and disconnect all power cords and external cables.
- Remove the cover (see Removing the top cover).
- Locate the UEFI boot backup jumper (J15) on the system board. Figure 1. UEFI boot backup jumper (J15) location
- Move the UEFI boot backup jumper (J15) from pins 1 and 2 to pins 2 and 3 to enable the UEFI recovery mode.
- Reinstall the server cover; then, reconnect all power cords.
- Restart the server. The system begins the power-on self-test (POST).
- Boot the server to an operating system that is supported by the firmware update package that you downloaded.
- Perform the firmware update by following the instructions that are in the firmware update package readme file.
- Turn off the server and disconnect all power cords and external cables, and then remove the cover (see Removing the top cover).
