Clearing the BIOS Admin Password Using Jumper J1E4

This procedure describes how to clear the BIOS admin password for the BIOS back to the default in case the user-selected password is lost of forgotten.

Step 1 Power off the server as described in the “Shutting Down and Powering Off the Server” section on page 3-8.

Step 2 Disconnect all power cords from the power supplies.

Step 3 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 4 Remove the top cover as described in the “Removing and Replacing the Server Top Cover” section on page 3-10.

Step 5 Move the shorting jumper to pins 2 and 3 of the J1E4 header (see Figure 2-6 on page 2-15).

Step 6 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 7 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 password reset. This is because the state of the jumper cannot be determined without the host CPU running. The password is then cleared.

Step 8 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 9 Remove the top cover from the server.

Step 10 Remove the shorting jumper from the header pins.

Note If you do not remove the jumper, the password is cleared every time that you power-cycle the server.

Step 11 Replace 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.
