bypass
v Pins 1 and 2: Normal operation (default).
v Pins 2 and 3: Clears Wake on LAN bypass.
J29 Password
override
When you change the position of this jumper, the server
bypasses the power-on password check. The next time you turn
on the server, the Setup Utility starts and you can change or
delete the power-on password. You do not need to move the
jumper back to the default position (pins 1 and 2) after the
password is overridden.
J22 Boot
recovery
v Pins 1 and 2: Normal operation (default).
v Pins 2 and 3: Enable the UEFI recovery mode.
Note: If no jumper is present, the server responds as if the jumper is on pins 1 and 2.
