Using the BIOS Recovery Jumper J1E5 to Recover Corrupt BIOS

This jumper is adjacent to the CMOS battery (see Figure 2-6 on page 2-15). You can use this jumper to force the server to flash a new BIOS, in the case of a system hang. For example, if the system hangs after a BIOS update, use this procedure to force the server to look for the new firmware.

Step 1 Download the BIOS update package and extract it to a temporary location.

Step 2 Copy the contents of the extracted UEFI folder to the root directory a USB thumb drive.

Step 3 Power off the server as described in the “Shutting Down and Powering Off the Server” section on page 3-8.

Step 4 Disconnect all power cords from the power supplies.

Step 5 Slide the server out the front of the rack far enough so that you can remove the top cover. You might have to detach cables from the rear panel to provide clearance.

Caution If you cannot safely view and access the component, remove the server from the rack.

Step 6 Remove the top cover as described in the “Removing and Replacing the Server in a Rack” section on page 3-9.

Step 7 Move the shorting jumper to pins 3 and 4 of the J1E5 header (see Figure 2-6 on page 2-15).

Step 8 Reinstall the top cover and reconnect AC power cords to the server. The server powers up to standby power mode, indicated when the Power LED on the front panel is amber.

Step 9 Insert the USB thumb drive into a USB port on the server.

Step 10 Return the server to main power mode by pressing the Power button on the front panel. The server is in main power mode when the Power LED is green.

Note You must allow the entire server to reboot to main power mode to complete the recovery. This is because the state of the J1E5 jumper cannot be determined without the host CPU running. The server automatically boots into the UEFI shell and updates the BIOS from the USB thumb drive.

Step 11 Wait for server to complete the BIOS update, then remove the USB thumb drive from the server.

Step 12 Press the Power button to shut down the server to standby power mode, and then remove AC power cords from the server to remove all power.

Step 13 Remove the top cover from the server.

Step 14 Move the shorting jumper from header pins 3 and 4, back to its default position on pins 1 and 2.

Note If you do not move the jumper, the server forces a recovery of the new BIOS every time that you power cycle the server.

Step 15 Replace the top cover, replace the server in the rack, replace power cords and any other cables, then power on the server by pressing the Power button.
