Jumper name
Description
Force power-on (J32)
The default position is pins 1 and 2. Change the position of this
jumper to pins 2 and 3 to force the server to start when you connect
the server to ac power.
Note:
Use the force power-on jumper only for diagnosing power
problems. POST might not be completed, and the server might not
start.
Power-on password (J33)
The default position is pins 1 and 2. Change the position of this
jumper to pins 2 and 3 to bypass the power-on password check.
Changing the position of this jumper does not affect the
administrator password check if an administrator password is set. If
the administrator password is lost, the microprocessor board must
be replaced.
For more information about passwords, see “Passwords” on page
66.
Wake on LAN bypass (J38)
The default position is pins 1 and 2. Move the jumper to pins 2 and
3 to prevent a Wake on LAN packet from waking the system when
the system is in the powered-off state.
