Chapter 2 Powering On and Configuring BIOS Settings 2-53
2.4 Resetting SP and BIOS Passwords Using
Jumper P4 or J12
The names and locations of this jumper differ between the Sun Fire X4100/X4200 and
the X4100 M2/X4200 M2 servers:
■ In Sun Fire X4100/X4200 servers this jumper is P4. See FIGURE 2-8 on page 55 for the
location.
■ In Sun Fire X4100 M2/X4200 M2 servers this is jumper J12. See FIGURE 2-9 on page
56 for the location.
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 nonconducting pointer
or 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 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 on page 1-5 or FIGURE 1-6 on
page 1-9 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 3.5, “Removing the Main Cover of the Sun Fire X4100/X4100 M2
Server” on page 3-6 or Section 3.8, “Removing the Main Cover of the Sun Fire
X4200/X4200 M2 Servers” on page 3-10.
5. Install the shorting jumper across the P4 or J12 header pins.
See
FIGURE 2-8 or FIGURE 2-9 for the jumper location. This jumper’s function is to
clear the ILOM SP password.
6. Reinstall the main cover to the server.
