2-20 | ni.comChapter 2 Installation and Configuration3. In the Devices and Interfaces tree, expand PXI System. Your PXI Express chassis isalready identified and appears in the PXI System tree.4. For each unidentified PXI Express chassis in the PXI System tree, right-click on the chassisand select the appropriate chassis model through the Identify As submenu. Furtherexpanding the PXI System branch shows all devices in the system that NI-VISA canrecognize.The PXI Express specification allows for many combinations of PXI Express chassis and systemmodules. To assist system integrators, PXI Express chassis and system module manufacturersmust document their products’ capabilities. PXI Express devices must provide a driver and/or.ini file for identification. For NI PXI Express chassis and controllers, these files are providedas part of the NI PXI Platform Services software included with your controller. Systemintegrators, configuration utilities, and device drivers can use these .ini files.The NI PXI Platform Services software uses the system module driver, chassis driver, andchassis.ini files to generate the PXI/PXI Express system description files (pxisys.iniand pxiesys.ini). Device drivers and other utility software read the pxiesys.ini andpxisys.ini files to obtain system information. For detailed information about initializationfiles, refer to the PXI Express specification at www.pxisa.org.Upgrading RAMYou can change the amount of installed RAM on the NI PXIe-8880 by upgrading theSO-DIMMs.To upgrade the RAM, remove the NI PXIe-8880 from the PXI Express chassis. To optimizememory capacity and system performance, use the same size and speed memory modules. Theuse of different size modules in each slot is supported, but system performance will be slowerthan using three matched modules. However, three mismatched modules could result in betterperformance than using a single module.National Instruments offers the following SO-DIMM for use with the NI PXIe-8880 controller.• PC4-1866 (DDR4 2133) 8 GB, 1 GB × 72, CL 15, 1.18 in. max(NI part number 783813-01)Note National Instruments has tested and verified that the DDR4 SO-DIMMs wesell work with the NI PXIe-8880. We recommend you purchase your DDR4SO-DIMM modules from National Instruments. Other off-the-shelf DDR4SO-DIMM modules are not guaranteed to work properly.Artisan Technology Group - Quality Instrumentation ... Guaranteed | (888) 88-SOURCE | www.artisantg.com
