Chassis Configuration
How do I set up the RMC-8357 to work with my PXIe chassis?
Configuration of the PXI system is handled through Measurement & Automation Explorer
(MAX), included with the software pre-installed on your RMC-8357. MAX creates the
pxisys.ini file, which defines the layout and parameters of your PXI system.
The configuration steps for single or multiple-chassis systems are the same. In MAX, select
Help»Help Topics»PXI to configure your chassis.
The PXI specification allows many combinations of PXIe chassis and system modules. To assist
system integrators, the manufacturers of PXIe chassis and system modules must document the
capabilities of their products. The minimum documentation requirements are contained in
files, which consist of ASCII text. System integrators, configuration utilities, and device drivers
can use these
The capability documentation for the chassis is contained in a chassis.ini file provided by
the chassis manufacturer. The information in this file is combined with information about the
system controller to create a single system initialization file called
Initialization). The RMC-8357 uses MAX to generate the pxisys.ini file from the
chassis.ini file.
Device drivers and other utility software read the pxisys.ini file to obtain system
information. For detailed information about initialization files, refer to the PXI specification

Troubleshooting
This chapter answers common troubleshooting questions you may have when using the
RMC-8357.
What if the RMC-8357 does not boot?
Several problems can cause a controller not to boot. Here are some things to look for and
possible solutions.
Things to Notice:
•Which LEDs come on? The power indicator LED should stay lit. The hard disk drive LEDs
should blink during boot as the disk is accessed.
•What appears on the display? Does it hang at some particular point (BIOS, Operating
System, and so on)? If nothing appears on the screen, try a different monitor. Does your
monitor work with a different PC? If it hangs, note the last screen output that you saw for
reference when consulting National Instruments technical support.
•What has changed about the system? Did you recently move the system? Was there
electrical storm activity? Did you recently add a new module, memory chip, or piece
of software?
•Has the system overheated? If the Overheat/FanFail LED is lit, this indicates overheating.
Unplug the AC power cord from the controller and allow it to cool down before powering
it on again.
Things to Try:
•Make sure the RMC-8357 is plugged in to a working power source.
•Make sure the monitor is plugged into the DisplayPort or DVI port. The VGA port is
disabled by default.
•Remove the power supply and reinsert it.
•Remove any nonessential cables or devices.
•Make sure the CPU and memory modules are properly seated in their slots.
•Recover the hard drive on the RMC-8357. (Refer to the OS Reinstallation and Recovery
section of Chapter 2, Installation and BIOS Setup.)
My RMC-8357 boots fine until I get to Windows, at which point I cannot read the screen.
This may include garbled output, white screen, black screen, or an out of synch message
from the monitor.
This problem usually results from having the video card output set past the limits of the monitor.
You will need to boot Windows in Safe Mode. To do this, reboot the RMC-8357. As Windows
begins to boot, hold down <F8>. You should now be able to reset the video driver to lower
settings. Try setting the resolution to 640 × 480 and the refresh rate to 60 Hz. Once you reboot,
you can raise these values again, using the test option in Windows. These settings are accessible
through the Advanced tab of the Display item in the Control Panel. Alternately, you can try a
different monitor, preferably a newer and larger one.
My system boots fine as long as a particular module is not in my chassis.
The most common cause of this is a damaged module. Try the module in a different chassis or
with a different controller. Also, remove any external cables or terminal blocks connected to the
system. If the module does not work in these cases, it is likely damaged. Contact the module
manufacturer for further troubleshooting.
Refer to the KnowledgeBase or product manuals section at
ni.com for more information
specific to the chassis and module with which you are having difficulties.
