6.1 CMOS Clear and Password Reset Usage Procedure
The CMOS Clear (J1D1) and Password Reset (J1D2) recovery features are designed such that
the desired operation can be achieved with minimal system downtime. The usage procedure for
these two features has changed from previous generation Intel server boards. The following
procedure outlines the new usage model.
6.1.1 Clearing the CMOS
To clear the CMOS, perform the following steps:
1. Power down the server. Do not unplug the power cord.
2. Open the server chassis. For instructions, see your server chassis documentation.
3. Move jumper (J1D1) from the default operating position, covering pins 1 and 2, to the
reset/clear position, covering pins 2 and 3.
4. Remove AC power.
5. Wait 5 seconds.
6. Move the jumper back to default position, covering pins 1 and 2.
7. Close the server chassis.
8. Power up the server.
The CMOS is now cleared and can be reset by going into the BIOS setup.
Note: Removing AC power before performing the CMOS Clear 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.
6.1.2 Clearing the Password
To clear the password, perform the following steps:
1. Power down server. Do not unplug the power cord.
2. Open the chassis. For instructions, see your server chassis documentation.
3. Move jumper (J1D20 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, wait 10 seconds or until POST completes.
6. Power down the server.
7. Open the chassis and move the jumper back to 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.
