PXIe-8238 Getting Started Guide
This document includes instructions for installing and configuring your PXIe-8238
module.
Products Covered
This document covers the following products:
■PXIe-8238 (142470x-010L)
Note Following the model number above is the specific NI assembly
number in parentheses. Ensure that the specifications of interest match
the NI assembly number printed on the board. x denotes all letter revisions
of the assembly.
Getting Started
This section includes instructions for unpacking and installing your PXIe-8238
module. It also describes the module's front panel connectors.
Unpacking
The PXIe-8238 ships in an antistatic package to prevent electrostatic discharge from
damaging device components. To prevent such damage when handling the device,
ground yourself using a grounding strap or by holding a grounded object, such as
your computer chassis, and complete the following steps:
1. Touch the antistatic package to a metal part of the chassis before removing
the device from the package.
Caution Never touch the exposed pins of connectors.
2. Remove the device from the package and inspect the device for loose
components or any other sign of damage.

Preparing the Environment
Ensure the environment you are using the PXIe-8238 in meets the following
specifications.
Ambient temperature range 0 °C to 55 °C (Tested in accordance with IEC-60068-2-1 and
IEC-60068-2-2.)

IEC-60068-2-56.)
Maximum altitude 2,000 m (800 mbar)
Pollution Degree 2
Indoor use only.
Note Refer to the PXIe-8238 User Manual for full PXIe-8238
specifications.
Hardware Installation
The following are general instructions for installing the PXIe-8238.
Complete the following steps to install the PXIe-8238 in your PXI Express chassis.
1. Power o your PXI Express chassis, but leave it plugged in while installing the
PXIe-8238. The power cord grounds the chassis and protects it from electrical
damage while you install the module.

Caution To protect both yourself and the chassis from electrical
hazards, leave the chassis o until you finish installing the
PXIe-8238.
2. Remove or open any doors or covers blocking access to the slot in which you
intend to install the PXIe-8238.
3. Touch a metal part of the chassis to discharge any static electricity that might
be on your clothes or body.
4. Make sure the injector/ejector handle is in its downward position. Be sure to
remove all connector packaging and protective caps from retaining screws on
the module.
5. Identify the slot in which the PXIe-8238 will be installed in the chassis. Refer to
the following table to determine which slot types the PXIe-8238 is compatible
with.

6. Align the PXIe-8238 with the card guides on the top and bottom of the slot.
Hold the handle as you slowly slide the module into the chassis until the
handle catches on the injector/ejector rail.
Caution Do not raise the injector/ejector handle as you insert the
PXIe-8238. It will not insert properly unless the handle is in its
downward position so that it does not interfere with the injector/
ejector rail on the chassis.
7. Raise the injector/ejector handle until the module firmly seats into the
backplane receptacle connectors. The front panel of the PXIe-8238 should be
even with the front panel of the chassis.
8. Tighten the bracket-retaining screws on the top and bottom of the front panel
to secure the PXIe-8238 to the chassis.
9. Replace or close any doors or covers to the chassis.

What do the LEDs on the front panel mean?
Refer to the LED status descriptions in the Front Panel Features section.
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 dierent
chassis or with a dierent 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 at ni.com/kb or product manuals section at ni.com/
manuals for more information specific to the module with which you are having
diiculties.
