Out-of-band manual recovery method

To recover the server firmware and restore the server operation to the primary
bank, complete the following steps:
1. Download the blade server UEFI firmware update from the World Wide Web
(see "Firmware updates" on page 34).
2. Turn off the server (see "Turning off the blade server" on page 14).
3. Remove the blade server from the BladeCenter unit (see "Removing the blade
server from the BladeCenter unit" on page 52).
4. Remove the server cover. See "Removing the blade server cover" on page 55
for more information.
5. Locate the UEFI boot block recovery switch (SW1-5) on the system board (see
"System-board switches" on page 16).
6. Use your finger to move switch SW1-5 to the ON position.
7. Replace the cover and reinstall the blade server in the BladeCenter unit,
making sure that the media tray is selected by the relevant blade server. See
"Closing the blade server cover" on page 56 and "Installing the blade server
in a BladeCenter unit" on page 53.
8. Restart the blade server (see "Turning on the blade server" on page 14). The
system begins the power-on self-test (POST).
9. Boot the server to the operating system or the F1 UEFI configuration menu.

to recover.
