a three-meter power cord, a Mini-COMBICON plug, an EMI suppression ferrite and safety documentation.<\/p>\n<p>Verify the input-power architecture before ordering. The source, cable, connectors, disconnect device, overcurrent protection and grounding arrangement must be suitable for the intended AC or high-voltage DC supply.<\/p>\n<h3>18-Slot PXI Express Architecture<\/h3>\n<p>The PXIe-1086DC provides one system-controller slot and 17 peripheral positions. Sixteen peripheral positions use hybrid connectors, and the remaining position is a dedicated PXI Express system timing slot.<\/p>\n<p>This capacity allows a single system to combine data acquisition, signal generation, switching, digital I\/O, programmable power, RF measurement, FPGA processing and communication interfaces.<\/p>\n<p>The controller position includes three adjacent system expansion slots. A four-slot embedded controller uses these positions, so controller width must be considered when calculating the remaining capacity.<\/p>\n<h3>Sixteen Hybrid Peripheral Slots<\/h3>\n<p>The 16 hybrid peripheral positions support compatible PXI Express modules and hybrid-compatible conventional PXI instruments. This provides greater flexibility when building or upgrading mixed-generation systems.<\/p>\n<p>Existing PXI modules can be retained while newer PXI Express instruments are added for applications requiring higher-speed data transfer or FPGA processing.<\/p>\n<p>Each module must be checked for connector, signaling-voltage, driver, operating-system, power and cooling compatibility. Never force an incompatible PXI connector into a hybrid slot.<\/p>\n<h3>Dedicated System Timing Slot<\/h3>\n<p>The dedicated PXI Express system timing slot provides specialized clocking and trigger resources for compatible timing and synchronization modules.<\/p>\n<p>A timing module can distribute reference clocks and triggers among instruments, coordinate several chassis or synchronize the PXI system with external equipment.<\/p>\n<p>This capability is valuable in phase-coherent acquisition, synchronized waveform generation, high-channel-count digitizer systems and hardware-in-the-loop testing.<\/p>\n<h3>12 GB\/s System Bandwidth<\/h3>\n<p>The PXIe-1086DC provides up to 12 GB\/s of aggregate system bandwidth between the controller and chassis backplane.<\/p>\n<p>The available bandwidth is allocated according to the backplane topology and installed controller. Actual throughput also depends on each module\u2019s PCI Express link, simultaneous transfers, storage performance and software processing.<\/p>\n<p>For continuous acquisition, calculate the data rate from every digitizer, RF instrument and FPGA module. Lower-bandwidth switching and communication modules generally place less demand on the backplane.<\/p>\n<h3>High-Voltage DC Input<\/h3>\n<p>The defining feature of the PXIe-1086DC is its support for 210 VDC to 300 VDC input. This high-voltage DC range is intended for facilities and specialized systems where a regulated DC distribution bus is available.<\/p>\n<p>The input is not designed for common low-voltage 12 V, 24 V or 48 V sources. Connecting a low-voltage DC supply will not provide the required operating voltage.<\/p>\n<p>High-voltage DC installation must be completed by qualified personnel using correctly rated conductors, connectors, protection devices, grounding and disconnect hardware.<\/p>\n<h3>Compatible AC Input Operation<\/h3>\n<p>Although designated as a DC chassis, the PXIe-1086DC power supply also accepts 100 VAC to 240 VAC nominal input. Its guaranteed AC operating range is 90 VAC to 264 VAC at 47 Hz to 63 Hz.<\/p>\n<p>This dual AC\/DC input capability allows the same chassis to be deployed in high-voltage DC environments or operated from conventional laboratory AC power when required.<\/p>\n<p>The power-cable and protection arrangement must be selected for the actual input source rather than the product name alone.<\/p>\n<h3>855 W Total Usable Power<\/h3>\n<p>The power system supplies up to 855 W of usable backplane power. This supports large configurations containing multiple acquisition, switching, RF and control modules.<\/p>\n<p>Total wattage is only one part of the power calculation. With a single supply, the specified maximum currents include 50 A at +3.3 V, 40 A at +5 V and 50 A at +12 V. Dual supplies increase the available current on these rails, subject to the 855 W total limit.<\/p>\n<p>The maximum combined power from the +12 V and \u221212 V rails with one power supply is 588 W. Verify the voltage-rail requirements of every installed module before operating the system.<\/p>\n<h3>Hot-Swappable Redundant Power Supplies<\/h3>\n<p>The PXIe-1086DC supports two redundant hot-swappable power supplies. When both are functional and the load remains within the supported redundancy budget, either supply can be removed without disconnecting system power.<\/p>\n<p>This architecture reduces the risk that a single supply failure will interrupt an important production, qualification or monitoring process.<\/p>\n<p>Redundancy requires the remaining supply to support the complete system load. A heavily loaded configuration can operate with two supplies but still exceed the capacity of one supply during a failure.<\/p>\n<h3>Fast Power-Supply Replacement<\/h3>\n<p>The specified mean time to repair for a power-supply shuttle is less than one minute. Captive screws and a collapsible handle allow a qualified technician to remove the supply from the chassis.<\/p>\n<p>When rear access is restricted, the chassis power drawer can provide an alternative service path. Power-drawer removal has different safety requirements and may require complete AC or DC disconnection.<\/p>\n<p>Always follow the service instructions for the exact operation being performed. Hot-swappable supplies do not make every part of the power drawer safe to remove while energized.<\/p>\n<h3>Single-Power-Supply Operation<\/h3>\n<p>The chassis can operate with one installed supply, but hardware redundancy is lost and the single-supply current limits apply.<\/p>\n<p>A power-supply filler panel, part number 784057-01, must be installed in the empty bay to meet the documented operational shock and vibration specifications.<\/p>\n<p>The filler panel also protects the unused bay and helps maintain the designed airflow path.<\/p>\n<h3>Redundant Front-Accessible Cooling Fans<\/h3>\n<p>Six 150 CFM fans are arranged as three columns of dual-stacked fans. The redundant design allows one fan assembly to be removed while the corresponding second fan continues operating.<\/p>\n<p>The fan assemblies are accessible from the front of the chassis and are hot swappable under supported conditions. This reduces service time in racks where rear access is limited.<\/p>\n<p>Never remove both fans from the same column. Removing both fans, or removing the remaining working fan in a column that already contains a failed unit, can cause the chassis to shut down.<\/p>\n<h3>Positive-Pressurization Cooling<\/h3>\n<p>Cooling air enters through the bottom and travels upward through the instrument slots before exhausting along the top of the chassis.<\/p>\n<p>Positive pressurization directs air through the installed modules. The power supplies use integrated fans with intake at the rear and exhaust through the top.<\/p>\n<p>Every unused instrument position must be covered with a filler panel. Open slots can allow air to bypass active modules and reduce cooling efficiency.<\/p>\n<h3>Cooling Clearance Requirements<\/h3>\n<p>Maintain at least 44.45 mm of clearance above and on both sides of the chassis. At least 76.20 mm of clearance is required behind it.<\/p>\n<p>The bottom air intake and top exhaust must remain unobstructed. Nearby equipment should not discharge hot air directly into the chassis intake.<\/p>\n<p>High-altitude operation up to 4,600 m requires the fan selector to be placed in High mode.<\/p>\n<h3>Chassis Health Monitoring<\/h3>\n<p>The PXIe-1086DC monitors power-supply health, backplane voltages, air-intake temperature, cooling-fan health and fan speed.<\/p>\n<p>Status LEDs provide visible notification of detected failures. This helps maintenance personnel distinguish a supply problem from a cooling or temperature fault.<\/p>\n<p>Monitoring information can be incorporated into preventive-maintenance procedures. Operators should define how the system will save data and place the DUT in a safe state when a serious fault occurs.<\/p>\n<h3>External 10 MHz Reference Input<\/h3>\n<p>A front-panel SMA connector accepts an external 10 MHz reference signal with a frequency tolerance of \u00b1100 ppm. The supported input amplitude is 200 mVpp to 5 Vpp for a sine or square waveform.<\/p>\n<p>The input impedance is 50 \u03a9. Use correctly terminated coaxial cabling to reduce reflections and clock-distribution errors.<\/p>\n<p>An external reference can synchronize the PXI backplane with another chassis, laboratory reference or compatible instrument.<\/p>\n<h3>External 10 MHz Reference Output<\/h3>\n<p>The chassis provides a front-panel SMA 10 MHz reference output. Its specified amplitude is 1 Vpp into 50 \u03a9 or 2 Vpp when unloaded.<\/p>\n<p>The output has a 50 \u03a9 nominal impedance and can be used to distribute the chassis reference to compatible external equipment.<\/p>\n<p>Verify the destination impedance and avoid adding unsupported passive loads that could reduce the output amplitude.<\/p>\n<h3>Backplane Timing and Triggering<\/h3>\n<p>The PXIe-1086DC distributes PXI_CLK10, PXIe_CLK100 and PXIe_SYNC100 through the backplane. Both principal reference clocks have a maximum frequency accuracy of \u00b125 ppm.<\/p>\n<p>PXI_CLK10 provides a maximum slot-to-slot skew of 500 ps. PXIe_CLK100 provides a maximum slot-to-slot skew of 100 ps.<\/p>\n<p>The chassis also supports PXI star triggering and PXI Express differential star resources. Actual system synchronization depends on the timing module, peripheral instruments, routes, software and external cabling.<\/p>\n<h3>Remote Power Control<\/h3>\n<p>The front-panel four-pin terminal-block connection and power-mode switch support integration with compatible remote power-control systems.<\/p>\n<p>This capability is useful in centralized test racks where several chassis and instruments must follow a coordinated startup or emergency-shutdown sequence.<\/p>\n<p>The AC\/DC input cable remains the main power disconnect. Do not locate the chassis where the input connector cannot be reached safely.<\/p>\n<h3>Rack-Mount System Integration<\/h3>\n<p>The chassis measures approximately 268.7 mm high, 467.1 mm wide and 476.5 mm deep. It weighs approximately 17.1 kg with two power supplies before controllers, modules and cables are added.<\/p>\n<p>Optional front and rear rack-mount kits support installation in compatible instrument cabinets. The symmetrical chassis mounting holes allow different rack orientations.<\/p>\n<p>Provide adequate mechanical support and use safe lifting procedures. Heavy cable bundles should be supported independently instead of hanging from module front panels.<\/p>\n<h2>PXIe-1086DC Applications<\/h2>\n<ul>\n<li>High-availability automated test equipment<\/li>\n<li>DC-powered industrial test systems<\/li>\n<li>Transportation and mobile test platforms<\/li>\n<li>Aerospace and defense validation<\/li>\n<li>Continuous production functional testing<\/li>\n<li>High-channel-count data acquisition<\/li>\n<li>Automotive ECU and HIL testing<\/li>\n<li>RF and wireless-device validation<\/li>\n<li>Power-electronics testing<\/li>\n<li>Semiconductor characterization<\/li>\n<li>Long-duration reliability testing<\/li>\n<li>Synchronized multi-instrument measurement<\/li>\n<\/ul>\n<h3>High-Availability Production Testing<\/h3>\n<p>The redundant power and cooling systems make the PXIe-1086DC suitable for production lines where an unexpected shutdown can interrupt manufacturing and delay delivery.<\/p>\n<p>Power supplies and fan assemblies can be replaced quickly, while chassis monitoring helps maintenance personnel identify the component requiring attention.<\/p>\n<h3>DC-Powered Industrial Installations<\/h3>\n<p>The high-voltage DC input allows the chassis to operate from compatible industrial DC distribution systems. This may reduce the need for an additional DC-to-AC conversion stage.<\/p>\n<p>The available source must remain within the 210 VDC to 300 VDC operating range and provide sufficient current for the chassis configuration.<\/p>\n<h3>Aerospace and Defense Testing<\/h3>\n<p>Aerospace test systems can combine avionics communication interfaces, digitizers, FPGA modules, switches, signal generators and sensor-measurement hardware.<\/p>\n<p>The system timing slot and external reference connections help coordinate instrumentation in synchronized validation environments.<\/p>\n<h3>Automotive ECU and HIL Validation<\/h3>\n<p>Vehicle interfaces, fault-insertion switches, real-time controllers, FPGA hardware and analog I\/O modules can be combined for ECU hardware-in-the-loop testing.<\/p>\n<p>Power and cooling redundancy are particularly useful for long regression sequences where a system interruption could require many hours of testing to be repeated.<\/p>\n<h3>High-Channel-Count Data Acquisition<\/h3>\n<p>The 17 peripheral positions can support multiple DAQ, temperature, strain, vibration and digitizer modules. A common chassis simplifies timing and communication between the instruments.<\/p>\n<p>Continuous streaming must remain within the backplane, controller, memory and storage limitations of the complete system.<\/p>\n<h3>RF and Wireless Testing<\/h3>\n<p>Compatible RF generators, analyzers, digitizers and switching modules can be installed for wireless component and subsystem testing.<\/p>\n<p>Applications transferring large RF data sets should calculate their combined throughput against the chassis\u2019s 12 GB\/s maximum bandwidth.<\/p>\n<h3>Reliability and Environmental Testing<\/h3>\n<p>The PXIe-1086DC can support long-duration qualification systems operating continuously for days or weeks. Redundant serviceable components help reduce the risk of losing progress because of a single supply or fan failure.<\/p>\n<p>Test applications should still save data regularly and implement a controlled response for temperature, power or communication faults.<\/p>\n<h2>PXIe-1086DC Installation Workflow<\/h2>\n<h4>Step 1: Confirm the Input-Power Source<\/h4>\n<p>Determine whether the system will operate from 210 VDC to 300 VDC or from 90 VAC to 264 VAC. Do not connect the chassis to a common 12 V, 24 V or 48 V DC source.<\/p>\n<h5>Verify Source Capacity<\/h5>\n<p>The input source must provide adequate voltage and current for the installed chassis configuration, including startup and worst-case module loading.<\/p>\n<h5>Verify Protection and Disconnect Hardware<\/h5>\n<p>Use appropriately rated conductors, overcurrent protection, grounding and a readily accessible disconnect method.<\/p>\n<h4>Step 2: Inspect the Chassis and Accessories<\/h4>\n<p>Check the chassis, power supplies, fans, power cord, filler panels, ferrite and terminal-block plug for damage. Confirm part number 787137-01.<\/p>\n<h4>Step 3: Prepare a Slot Map<\/h4>\n<p>List the controller, system timing module and peripheral instruments. Record module width, connector type, bandwidth, power and cooling requirements.<\/p>\n<p>Reserve the dedicated timing slot for the synchronization module and account for any multi-slot controller or instrument.<\/p>\n<h4>Step 4: Calculate the Power Budget<\/h4>\n<p>Confirm that the configuration remains within the 855 W total power limit and the current ratings for each voltage rail.<\/p>\n<p>For redundant operation, make sure one power supply can support the required system load if the second supply fails or is removed.<\/p>\n<h4>Step 5: Install the Chassis<\/h4>\n<p>Place the chassis on a stable bench or install it with compatible front and rear rack-mount hardware. Maintain the specified top, side and rear clearances.<\/p>\n<p>Ensure that the bottom intake remains open after rack shelves, cable trays and neighboring equipment are installed.<\/p>\n<h4>Step 6: Connect Protective Ground<\/h4>\n<p>Connect the chassis only through the approved grounding and input-power arrangement. Qualified personnel should perform high-voltage DC wiring.<\/p>\n<p>Install the supplied EMI suppression ferrite as directed by the chassis documentation.<\/p>\n<h4>Step 7: Power Off Before Installing Modules<\/h4>\n<p>Disconnect the input source and confirm that the chassis is de-energized. Follow antistatic precautions while handling the controller and peripheral modules.<\/p>\n<h4>Step 8: Install the System Controller<\/h4>\n<p>Insert the embedded controller or remote-control interface into the system slot. Align it with the guides, seat the backplane connectors fully and tighten the retaining screws.<\/p>\n<h4>Step 9: Install the Timing and Peripheral Modules<\/h4>\n<p>Install the timing module in the dedicated system timing slot. Place remaining instruments according to the prepared slot map.<\/p>\n<p>Confirm that no peripheral module exceeds the 38.25 W dissipation limit.<\/p>\n<h4>Step 10: Install Filler Panels<\/h4>\n<p>Cover every unused instrument position with an appropriately sized filler panel. When only one supply is installed, fit power-supply filler panel 784057-01 in the empty bay.<\/p>\n<h4>Step 11: Connect Input Power<\/h4>\n<p>Connect both power supplies when redundant operation is required. Where the installation permits, design the upstream distribution so one failure does not remove power from both supplies.<\/p>\n<h4>Step 12: Power On and Verify Status<\/h4>\n<p>Turn on the chassis and check all supply, fan and temperature indicators. Confirm that no voltage or cooling fault is reported.<\/p>\n<h4>Step 13: Detect the Installed Hardware<\/h4>\n<p>Start the controller and use NI Measurement &amp; Automation Explorer to verify the chassis and peripheral modules. Install the required drivers and complete the available self-tests.<\/p>\n<h4>Step 14: Test Redundancy Safely<\/h4>\n<p>After confirming that the load remains within single-supply capacity, follow the approved procedure to verify that either supply can support the system.<\/p>\n<p>Do not test fan redundancy by removing both fans from the same vertical column.<\/p>\n<h2>PXIe-1086DC Troubleshooting<\/h2>\n<h4>The Chassis Does Not Power On<\/h4>\n<p>Measure the input source and confirm that it falls within the specified DC or AC operating range. Check the power cable, disconnect device, fuses and front-panel power-control mode.<\/p>\n<p>If remote power control is used, inspect the Mini-COMBICON wiring and confirm that an external inhibit signal is not preventing startup.<\/p>\n<h4>A 24 V or 48 V DC Supply Does Not Start the Chassis<\/h4>\n<p>The PXIe-1086DC requires 210 VDC to 300 VDC. Its DC input is not designed for common low-voltage industrial sources.<\/p>\n<p>Use a correctly rated power-conversion system if only low-voltage DC is available.<\/p>\n<h4>One Power Supply Shows a Fault<\/h4>\n<p>Check its input connection, seating and status indicator. Confirm that the second supply is operating and can support the installed load.<\/p>\n<p>Replace the failed supply with the compatible 782106-01 unit to restore redundancy.<\/p>\n<h4>The System Shuts Down When One Supply Is Removed<\/h4>\n<p>The remaining supply may not have input power, or the system load may exceed the single-supply current capacity.<\/p>\n<p>Review each voltage rail and reduce the installed load before repeating the redundancy test.<\/p>\n<h4>A Fan Fault Is Reported<\/h4>\n<p>Identify the affected assembly using the status indicators. Inspect the air path and replace the defective fan with a compatible 782107-01 assembly.<\/p>\n<p>Do not remove the second working fan in the same column, because the chassis can shut down when both fans in one column are absent.<\/p>\n<h4>The Chassis Reports Excessive Temperature<\/h4>\n<p>Check the bottom intake, top exhaust, filler panels and required installation clearances. Confirm that every fan operates and that the intake air remains within the specified temperature range.<\/p>\n<p>Set the fan selector to High when required by altitude or environmental conditions.<\/p>\n<h4>An Installed PXI Module Is Not Detected<\/h4>\n<p>Power down the chassis and reseat the module. Confirm hybrid-slot compatibility and install the correct device driver.<\/p>\n<p>Use NI MAX to rescan the system. Moving the module to another supported position can help distinguish a module problem from a slot issue.<\/p>\n<h4>Data Throughput Is Lower Than Expected<\/h4>\n<p>Review the controller link, chassis topology and combined data rate of all active modules. The 12 GB\/s figure is an aggregate maximum rather than a guaranteed bandwidth for every slot.<\/p>\n<p>CPU workload, memory use, DMA settings and storage performance can also limit sustained throughput.<\/p>\n<h4>External Clock Synchronization Does Not Work<\/h4>\n<p>Confirm that the external source is 10 MHz within \u00b1100 ppm and has an amplitude between 200 mVpp and 5 Vpp.<\/p>\n<p>Use 50 \u03a9 cabling and verify the input\/output routing, termination and timing-module configuration.<\/p>\n<h4>The Chassis Produces High Fan Noise<\/h4>\n<p>High fan mode produces substantially more acoustic noise than Auto mode. Increased speed may be required by temperature, altitude or the selected cooling configuration.<\/p>\n<p>Do not reduce fan speed if doing so would violate the cooling requirements of the installed modules.<\/p>\n<h4>The Chassis Fails a Shock or Vibration Requirement<\/h4>\n<p>If only one power supply is installed, verify that filler panel 784057-01 is correctly fitted in the empty supply bay.<\/p>\n<p>Also confirm that the chassis, rack hardware, modules and cables are properly secured.<\/p>\n<h2>PXIe-1086DC Comparison<\/h2>\n<table>\n<tbody>\n<tr>\n<th>\u0424\u0443\u043d\u043a\u0446\u0438\u044f<\/th>\n<th>PXIe-1086DC<\/th>\n<th>PXIe-1086<\/th>\n<th>PXIe-1085<\/th>\n<th>PXIe-1095<\/th>\n<\/tr>\n<tr>\n<td>\u041e\u0431\u0449\u0435\u0435 \u043a\u043e\u043b\u0438\u0447\u0435\u0441\u0442\u0432\u043e \u0441\u043b\u043e\u0442\u043e\u0432<\/td>\n<td>18<\/td>\n<td>18<\/td>\n<td>18<\/td>\n<td>18<\/td>\n<\/tr>\n<tr>\n<td>Hybrid Peripheral Slots<\/td>\n<td>16<\/td>\n<td>16<\/td>\n<td>16<\/td>\n<td>5<\/td>\n<\/tr>\n<tr>\n<td>System Timing Slot<\/td>\n<td>\u0414\u0430<\/td>\n<td>\u0414\u0430<\/td>\n<td>\u0414\u0430<\/td>\n<td>\u0414\u0430<\/td>\n<\/tr>\n<tr>\n<td>Maximum System Bandwidth<\/td>\n<td>12 GB\/s<\/td>\n<td>12 GB\/s<\/td>\n<td>Up to 24 GB\/s<\/td>\n<td>24 \u0413\u0411\/\u0441<\/td>\n<\/tr>\n<tr>\n<td>Maximum Slot Dissipation or Cooling<\/td>\n<td>38.25 W<\/td>\n<td>38.25 W<\/td>\n<td>38 \u0412\u0442<\/td>\n<td>82 \u0412\u0442<\/td>\n<\/tr>\n<tr>\n<td>Power Input<\/td>\n<td>210\u2013300 VDC or 90\u2013264 VAC<\/td>\n<td>90\u2013264 VAC<\/td>\n<td>AC<\/td>\n<td>AC<\/td>\n<\/tr>\n<tr>\n<td>Redundant Power and Cooling<\/td>\n<td>\u0414\u0430<\/td>\n<td>\u0414\u0430<\/td>\n<td>No<\/td>\n<td>\u0414\u0430<\/td>\n<\/tr>\n<tr>\n<td>Primary Advantage<\/td>\n<td>High-voltage DC input with high-availability hardware<\/td>\n<td>Redundant architecture for conventional AC installations<\/td>\n<td>Higher bandwidth with 16 hybrid positions<\/td>\n<td>Higher bandwidth and per-slot cooling<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<h3>PXIe-1086DC vs PXIe-1086<\/h3>\n<p>\u0417\u0435\u043c\u043b\u044f <a href=\"https:\/\/pxisource.com\/ru\/product\/pxie-1086\/\">PXIe-1086<\/a> and PXIe-1086DC share an 18-slot layout, 16 hybrid slots, a system timing slot, 12 GB\/s bandwidth, 855 W usable power and redundant serviceable hardware.<\/p>\n<p>The principal difference is input power.
