Keysight M9037A PXIe Embedded Controller User Guide 49
Things to not do Using the Controller
To avoid leaving Windows in an unknown state, the front panel ON button can be
used with the rear panel Inhibit signal. In this situation, however, the chassis
power is no longer completely controlled remotely, and local interaction is
required.
If the chassis and M9037A are powered up, momentarily pressing the ON button
causes an orderly shutdown of the M9037A, but the chassis remains powered
and the M9037A System Status LED HS (Blue) remains on. At this point, you
have two options:
- Momentarily press the ON button again to turn on the M9037A and bring up
Windows.
- Complete the power down process by grounding the Inhibit signal (pin 5 of
the rear panel DB-9 connector).
If the chassis and M9037A are powered up, pressing the chassis ON button for
greater than 5 seconds causes a forced shut down of Windows but, as before, the
chassis will not be powered off. At this point, you have the same two options
listed in the previous paragraph. However, Windows safe mode may be displayed
because of the forced shut down of Windows.
Things to not do
As with any PC, there are several system-level settings and files that you should
not change, move, or delete as this could cause a number of difficulties.
Windows Registry
Do not manually make any changes to the registry unless you know exactly what
you are doing. Making changes to the registry could affect the controller’s ability
to boot-up, execute programs, and display desired information.
Application Software
Do not remove files under the C:\Program Files folder by any means other than
using the Add or Remove Programs utility found on the Control Panel. Do not
remove any software application that was preinstalled by Keysight, even using
the Add or Remove Program Utility, unless you are instructed by Keysight to do
so while performing an update.
SSD Drive
Do not repartition the Solid State Drive (SSD) drive or rename any of the existing
partitions. Doing so could cause the controller to either not have the disk space
required or not be able to find needed data.
