Installed modules appear under the name of their associated chassis.
3. Expand your Chassis tree item.
MAX lists all modules installed in the chassis. Your default names may vary.
Note
installed modules. If the module is still not listed, power off the system, ensure
the module is correctly installed, and restart.
4. Record the identifier MAX assigns to the hardware. Use this identifier when
programming the PXIe-4135.
5. Self-test the hardware by selecting the item in the configuration tree and clicking Self-
Test in the MAX toolbar.
The MAX self-test performs a basic verification of hardware resources.

Testing the Safety Interlock

To ensure safe operation of the PXIe-4135, periodically test the safety interlock for proper
functionality. The recommended test interval is at least once per day of continuous usage.

Testing with an Application Development Environment

1. Disconnect the output connector from the PXIe-4135 front panel.
2. Ensure that the safety interlock input on the test fixture is closed.
3. Set the niDCPower Output Function property or NIDCPOWER_OUTPUT_FUNCTION
attribute to DC Voltage for the PXIe-4135.
4. Set the voltage level range to 200 V, and set the voltage level to 42.4 V.
5. Set the current limit range to 1 mA, and set the current limit to 1 mA.
6. Initiate the session.
7. Verify that the Voltage Status Indicator is amber.
8. Open the safety interlock input using the test fixture.
9. Verify that the Voltage Status Indicator is red.
10. Reset the device using the niDCPower Reset VI or the niDCPower Reset function.
11. Verify that the Voltage Status Indicator is green.

device and contact an authorized NI service representative to request a Return
Material Authorization (RMA).

Testing with the NI-DCPower Soft Front Panel

1. Disconnect the output connector from the PXIe-4135 front panel.
2. Ensure that the safety interlock input on the test fixture is closed.
3. In the NI-DCPower SFP, set Output Function to DC Voltage.
4. Set Voltage Level Range to 200 V, and set Voltage Level to 42.4 V.
