Two conditions A and B for connection are listed below: If computer’s PCIe slot to be linked with NA255A-G4 is PCIe 4.0 ×16 or PCIe 4.0 x8, you don’t need to make any change to the switch setting on NA255A-G4 backplane because NA255A-G4 is already set to work with computer’s PCIe 4.0 x16/x8 slot by default. - Page 9 3. Remove the L shape metal bracket at rear of NA255A-G4 through loosening the screw on metal bracket by screwdriver. 4. Install one graphics/third-party PCIe card into a PCIe ×16 slot within NA255A-G4 chassis and fasten the card with screw by screwdriver.
- Page 10 NOTICE When long length and heavy weight graphics card is to be installed in NA255A-G4, it’s strongly recommended the graphics card holder is utilized/installed to add stability to heavy weight GPU card within the chassis. The steps for card holder installation are given as follows: (A) Hold the supplied graphics card holder.
