9.1
BIOS Default (CMOS Clear) and Password Clear Usage Procedure
The BIOS default (J2J3) and Password Clear (J1C6) recovery features are designed to achieve
the desired operation with minimum system down time. The usage procedure for these two
features has changed from previous generation Intel
®
server boards. The following procedure
outlines the new usage model.
9.1.1
Clearing CMOS (BIOS default)
1. Power down the server and unplug the AC power cord.
2. Open the server chassis. For instructions, see your server chassis documentation.
3. Move the jumper (J2J3) from the default operating position (covering pins 1 and 2) to the
reset/clear position (covering pins 2 and 3).
4. Wait 5 seconds.
5. Move the jumper back to 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.
Note: Removing AC power before performing the CMOS Clear operation causes 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.
