Activity Within Setup - HP Vectra VA6 Technical Reference Manual

independent mini power supply provides the power necessary to keep the
network chip half awake (see page 6 for electrical specifications), and ready
to receive a wake-up signal. This is the only signal it can respond to in this
state.
The network chip sends a signal over the HP external start connector, where
it is received by the special network remote power chip. This in turn
switches on the main power supply.
The HP Vectra XA 6/xxx PC boots normally from whatever operating
system is installed, just as if the power supply had been switched on from
the external power switch. The display does not itself need to have RPO. If a
password has been set, the
enabled, to allow the operating system to boot.
At the end of the session, the HP Vectra XA 6/xxx PC needs to be shut
down again. This can be achieved remotely if it is running Windows 95.
Otherwise, using remote DMI, it can be configured to go back to Suspend
mode.

Activity within Setup

Since the user is not physically present, the level of security must be tighter.
There must be a distinction between the user-boot process, and the RPO-
boot process. HP provides all the necessary Setup options to keep users
from interfering with the PC during the remote session. Administrators can
set the management package to toggle on options like:
• Keyboard lock mode: This offers the same suite of security features as the
external "keyboard lock" button (keyboard, mouse, reset and power
button disabled).
• Floppy disable: this makes sure the PC cannot be disrupted by re-booting
from a diskette.
RPO is available when the POST routines have finished executing. It is
initialized by an SMI which is triggered from the mains power button.
A power failure when the PC is in RPO mode will deactivate the RPO
feature. RPO is intended for resource management (such as virus cleaners,
nightly backups, etc.), not for crisis management (thunderstorm recovery,
power failure, etc.).
