Note: Removing AC power before performing the Restoring BIOS Defaults operation will cause
the system to automatically power up and immediately power down, after the procedure is
followed and AC power is re-applied. If this happens, remove the AC power cord again, wait 30
seconds, and re-install the AC power cord. Power up the system and proceed to the <F2> BIOS
Setup utility to reset the desired settings.
7.1.2 Clearing the Password
To clear the password, perform the following steps:
1. Power down the server. Do not unplug the power cord.
2. Open the chassis. For instructions, see your server chassis documentation.
3. Move jumper (J1E8) from the default operating position (covering pins 1 and 2) to the
password clear position (covering pins 2 and 3).
4. Close the server chassis.
5. Power up the server and wait 10 seconds or until POST completes.
6. Power down the server.
7. Open the chassis and move the jumper back to the default position (covering pins 1
and 2).
8. Close the server chassis.
9. Power up the server.
The password is now cleared and can be reset by going into the BIOS setup.
7.2 Integrated BMC Force Update Procedure
When performing the standard Integrated BMC firmware update procedure, the update utility
places the Integrated BMC into an update mode, allowing the firmware to load safely onto the
flash device. In the unlikely event that the Integrated BMC firmware update process fails due to
the Integrated BMC not being in the proper update state, the server board provides a BMC
Force Update jumper (J1H2), which forces the Integrated BMC into the proper update state.
The following procedure should be followed in the event the standard Integrated BMC firmware
update process fails or if the Integrated BMC becomes corrupted in such a way as to prevent
the system from booting.
1. Power down and remove the AC power cord.
2. Open the server chassis. For instructions, see your server chassis documentation.
3. Move jumper from the default operating position (covering pins 1 and 2) to the enabled
position (covering pins 2 and 3).
4. Close the server chassis.
5. Reconnect the AC cord and power up the server.
