7.1 BIOS Defaults and Password Clear Usage Procedure
The BIOS Default (J1E7) and Password Clear (J1E8) 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.
7.1.1 Restoring BIOS Defaults
To restore BIOS Defaults, 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 (J1E7) 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. Remove AC power.
6. Move the jumper back to the default position (covering pins 1 and 2).
7. Close the server chassis.
8. Power up the server.
The BIOS defaults are now restored and can be reset by going into the BIOS setup.
