Step 13
Slide the BIOS recovery DIP switch from the closed position back to the default position 1 (see
).
Note
If you do not move the jumper, after recovery completion you see the prompt, “Please remove
the recovery jumper.”

Replace the top cover, replace the server in the rack, replace power cords and any other cables, and then
power on the server by pressing the
Power
button.
Using the Clear Password DIP Switch
See
for the location of this DIP switch. You can use this switch to clear the administrator
password.
Step 1
Power off the server as described in
Shutting Down and Powering Off the Server, 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
Removing and Replacing the Server Top Cover, page 3-9
Step 5
Slide the clear password DIP switch from position 2 to the closed position (see
).
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, not just the service processor, to reboot to main power mode
to complete the reset. The state of the jumper cannot be determined without the host CPU
running.
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
Slide the clear password DIP switch from the closed position back to default position 2 (see
).
Note
If you do not move the jumper, the password is cleared every time that you power-cycle the
server.
