In-band manual recovery method
To recover the server firmware and restore the server operation to the primary
bank, complete the following steps:
1. Read the safety information that begins on page vii and “Handling
static-sensitive devices” on page 135. This information will help you work
safely.
2. Turn off the server, and disconnect all power cords and external cables.
3. Remove the server cover. See “Removing the cover” on page 145 for more
information.
4. Locate the UEFI boot recovery jumper block (JP3) on the system board.
5. Remove any adapters that impede access to the boot recovery jumper block
(JP3) (see “Removing an adapter from the PCI riser-card assembly” on page
156).
6. Move the UEFI boot recovery jumper block (JP3) 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 “Installing an adapter on
the PCI riser-card assembly” on page 157).
8. Reinstall the server cover (see “Installing the cover” on page 146).
9. Reconnect all power cords and external cables and 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.
