Step 4: Install the CardBe careful there is no mechanical part of the PC that could damage thepower adaptor cable.2. The U5310A features a x8 PCIe bus interface, andshould be installed in either a x8 or x16 PCIe slot.3. When installing the U5310A, ensure that it hasoptimum cooling. Do not install it in a position wherethe integrated cooling fans may be obstructed.4. The card requires an additional auxiliary 4-pin powerconnection.If your PC has spare 4-pin Molex power con-nectors, simply connect the power cable to it.If your PC only has the newer SATA powerconnectors, use the supplied adapter 8121-2533.5. Replace any covers and switch-on the PC. Check the card front panel indicators - a fewseconds after the boot process, both the 'Status' and 'DPU' LEDs should be green.The SATA power adaptor (8121-2533) should be connected to a singlecard in order to guaranty the correct power supply and behavior of theADC Card.The U5310A is optionally supplied with a card retainer (included if ordered as U5300A-001, oravailable separately by ordering stand alone extender). The card retainer is able to pick up onslots at the end the full-length PCIe slot and provide additional support for the card. Use of thiscard retainer is highly recommended, in particular when the PC motherboard is orientedvertically. However, if your PC hardware does not provide end slots, the card retainer may beremoved from the card.Fitting the card with the optional card retainer into your PC1. Loosen (but do not remove) the screw (A) holding the rear card retainer, and slide ittowards the fans. Note that there are screws only on one side: there is no screw on thebottom side.2. Insert the card into the PCIe slot of the PC, ensuring that it is fully seated into the PCIebus connector.3. Fix the card to the PC either by fitting a screw, or by using a method compliant with yourPC model.4. Fully extend the card retainer and ensure that it is inside the PC chassis support slot.5. Tighten the screw (A) (0.5 Nm torque).12 Acqiris U5310A Startup Guide
