- Power down the server and unplug the power cord(s).
- Open the Server Chassis. For instructions, see your chassis documentation.
- Move jumper from the default operating position pins 1 - 2 (default) to the reset/clear position pins 2 - 3.
- Wait 5 seconds.
- Move the jumper back to default position pins 1 - 2
- Close the Server Chassis.
- Install AC power cords.
- Power up the server and access the BIOS setup utility by <F2>.
- Verify the BIOS default operation was successful by viewing the Error Manager Screen. Two errors should be logged:
