2.4 Resetting SP and BIOS Passwords Using
Jumper P4
This procedure describes how to reset the Administration password (the root
password) for the ILOM Service Processor back to the default after it has been set
once during initial setup.
Note – This procedure simultaneously removes any BIOS password that was set.
1. Shut down the server to standby power mode by using a ballpoint pen or other
stylus to press and release the recessed Power button on the front panel.
See Section 2.2, “Powering Off the Server” on page 2-3.
2. Disconnect the AC power cords from the server.
Caution – Before handling components, attach an ESD wrist strap to the grounding
post that is built into the rear of the chassis (see
FIGURE 1-2 or FIGURE 1-5 for the
location). The system’s printed circuit boards and hard disk drives contain
components that are extremely sensitive to static electricity.
3. If the server is in a rack, slide it far enough from the rack so that you can remove
the main cover. If you cannot safely view and access the motherboard, remove the
server from the rack.
4. Remove the main cover from the server.
See Section 3.2.2, “Removing the Main Cover” on page 3-3 or Section 4.2.2, “Removing
the Main Cover” on page 4-3.
5. Install the shorting jumper across the P4 header pins.
See
FIGURE 2-4 for the P4 jumper location. The P4 jumper’s function is to clear the
ILOM SP password.
6. Reinstall the main cover to the server.
7. Reconnect AC power cords to the server.
The server powers up to standby power mode, indicated when the Power/OK LED
on the front panel is flashing.
