reservations and routing are used whenever possible. If static reservations are required, static
reservation of trigger lines can be implemented by the user in MAX through the
Triggers
tab.
Fan Configuration in MAX
You can configure fan behavior using software settings in MAX.
The PXIe-1090 supports both Auto and High fan modes for both the 38 W and 58 W cooling
profiles. Refer to the
Fan Mode
section for more information about these modes.
You may also select a Manual fan mode. In this mode, you may manually set the fan speeds to
achieve the desired performance.
Note
You may not set the fan speeds or power settings lower than the minimum
level required to maintain required cooling levels.
Complete the following steps to change the fan settings in MAX .
1.
In the Configuration tree, click on the PXI chassis you want to configure.
2.
In the right-hand pane, click on the
Settings
tab.
3.
In the
Fans
group, select the desired Mode and Cooling Profile using the drop-down
menus.
4.
Click the
Save
button. Shortly after clicking the
Save
button, you should see the fan
speeds change.
Using System Configuration and Initialization Files
The PXI Express specification allows many combinations of PXI Express chassis and system
modules. To assist system integrators, the manufacturers of PXI Express chassis and system
modules must document the capabilities of their products. The minimum documentation
requirements are contained in
.ini
files, which consist of ASCII text. System integrators,
configuration utilities, and device drivers can use these
.ini
files.
The capability documentation for the PXIe-1090 chassis is contained in the
chassis.ini
file on the software media that comes with the chassis. The information in this file is combined
with information about the system controller to create a single system initialization file called
pxisys.ini
(PXI System Initialization). The system controller manufacturer either provides
a
pxisys.ini
file for the particular chassis model that contains the system controller or
provides a utility that can read an arbitrary
chassis.ini
file and generate the corresponding
pxisys.ini
file. System controllers from NI provide the
pxisys.ini
file for the
PXIe-1090 chassis, so you should not need to use the
chassis.ini
file. Refer to the
documentation provided with the system controller or to
for more information
on
pxisys.ini
and
chassis.ini
files.
Device drivers and other utility software read the
pxisys.ini
file to obtain system
information. The device drivers should have no need to directly read the
chassis.ini
file.
For detailed information regarding initialization files, refer to the PXI Express specification at
www.pxisa.org
