FAQ

Product-specific questions

Product-specific answers based on available technical information.

What is the NI PXIE-8861?

NI identifies the PXIe-8861 as a “PXIe, 2.8 GHz Quad-Core PXI Controller” and describes it as a PXI Express/CompactPCI Express embedded controller or system controller.

Does every PXIE-8861 have the same operating system or security configuration?

No. NI lists multiple PXIe-8861 commercial part numbers with different configurations, including LabVIEW RT, Windows 10 IoT LTSC 21H2 64-bit, no-TPM options, and a removable-drive/no-drive version. A specific installed variant should not be assumed without the exact part number.

What chassis space does the PXIE-8861 require?

According to NI specifications, the PXIe-8861 is a four-wide 3U PXI Express module that requires one system slot plus three controller expansion slots.

Is the removable-drive shuttle standard on all PXIE-8861 units?

NI indicates the PXIe-8861/PXIe-8862 shuttle removable HDD is included specifically with part number 786986-01, so it should be treated as configuration-specific rather than assumed for every PXIe-8861.
