Clear password jumper
Use the jumper to erase forgotten passwords, such as an administrator password and a user password.
To clear passwords, do the following:
1. Remove all external media from the drives and turn off all attached devices and the server. Then,
disconnect all power cords from electrical outlets and disconnect all cables that are connected to
the server.
2. If the server is installed in a rack cabinet, remove the server from the rack cabinet and place it on a flat,
clean, and static-protective surface. See the Rack Installation Instructions that comes with the server. If
the server is in tower form factor, lay the server on its side for easier operation.
3. Remove the server cover. See “Removing the server cover” on page 70.
