Step 3: Install the M9038A Embedded Controller
Removing the M9038A from the Chassis
To remove the M9038A controller, reverse the previous procedure. Shut down
the operating system to power-down the chassis. Loosen the four captive
screws, press down on the ejector/injector handle and pull outwards to release
the module from the backplane. Pull the module towards you until it is free of the
chassis.
Power On Sequence
The M9038A controller, like any PC, will boot with the installed operating system.
Refer to the M9038A User Guide for detailed power on and configuration
sequence information.
Power Off Sequence
As with any PC, Windows-based instruments should not be shutdown by either
turning off the power via an external power source or by pulling the power plug
out from the chassis rear panel. This could corrupt the operating system. One
method to shut down the controller is to execute the Windows shutdown process
which shuts down the M9038A controller then turns off the PXIe chassis. A
second method, if the chassis rear panel INHIBIT switch is set to DEF, is to
momentarily press the front panel button. Either method shuts down the
M9038A safely.
Power Down Modes
Keysight's M9038A defaults to the Windows Ultimate Performance Power Plan.
This plan does not allow the controller display to shut off or the controller to
enter a sleep mode.

Keysight M9038A PXIe Embedded Controller Startup Guide
Depending on the system configuration, the BIOS may take 90
seconds (or longer) to boot. During this time, the Keysight splash
screen (the Keysight logo) is present and it may appear that
nothing is happening. This is generally caused by the inclusion of
certain devices in the switch fabric (such as a RAID controller) that
require a longer time for PCI enumeration.
You cannot enable the Microsoft Windows Sleep mode. It is
disabled to prevent the controller from entering the Sleep mode
while it is running a user test program.
If you have a USB keyboard with a Sleep button (sometimes this is
a key with a crescent moon logo), do not use it.
