Description
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 up when you
connect the server to ac power.
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 I/O board must be replaced.
The default position is pins 1 and 2 (use the primary page during
startup). Move the jumper to pins 2 and 3 to use the secondary
page during startup.
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.
