7.1 CMOS Clear and Password Reset Usage Procedure
The CMOS Clear (J1E6) and Password Reset (J1E4) recovery features are designed to achieve

server boards. The following procedure
outlines the new usage model.
7.1.1 Clearing the CMOS

2. Open the server chassis. For instructions, see your server chassis documentation.
3. Move the jumper (J1E6) from the default operating position (covering pins 1 and 2) to
the reset/clear position (covering pins 2 and 3).
4. Wait five seconds.
5. Move the jumper back to the default position, covering pins 1 and 2.
6. Close the server chassis and reconnect the AC power cord.
7. Power up the server.
The CMOS is now cleared and you can reset it by going into the BIOS setup.
