Secure Panel Setting Question

["Justin C. Haase" <JHaase@xxxxxxxxxxxxx>]

Folks,

Got a trivia question for you.  Been reading up on IBM's definition of the
"secure" mode on the control panel.  It says, and I quote:

"Use SECURE mode to prevent use of the control panel to perform an IPL.
This mode is not a form of IPL; it is a means to prevent an unauthorized or
inadvertent IPL from the control panel."

So - the question is this - if I put a box in secure mode and yank the
keystick, will I still be able to perform a PWRDWNSYS and IPL normally?
Does SECURE default to normal IPL mode (unattended) or will it go to manual
mode, all the time saying SECURE on the control panel?

Thanks in advance for your help, all!
