Step 5

3. Insert a PCIe add-on/graphics card into PCIe ×16 slot and 

    tighten it with a screw. If you are installing a graphics card 

    that requires extra power resources, connect the 6 pin PCI 

    Express power resource provided by NA260A to the 6 pin 

    PCI Express power connector on graphics card, or connect 

    the 6+2 pin PCI Express power resource provided by 

    NA260A to the 8 pin PCI Express power connector on 

    graphics card.

4. Place the top cover back to TurboBox Rac NA260A, and 

    tighten the two thumbscrews to fasten the top cover.

5. Connect the end of PCIe ×8 cable to PCIe ×8 connector on 

    rear panel of TurboBox Rac NA260A. Also, connect the end 

    of power cord to power receptacle on TurboBox Rac NA260A 

    and the other end of power cord to a grounded outlet or 

    power strip.

Note: 

there are three hot-swappable 

120×120×25 mm cooling 

fans for ventilation inside 

TurboBox Rac NA260A. 

You may simply draw the 

cooling fans out by pulling 

the L type metal handle on 

the fan modules.

Power On TurboBox Rac NA260A

For Windows operating system

motherboard 

NA260A

Rackmount External PCIe to GPU Enclosure

The default setting is the jumper being placed over pin 9 and 

pin 10 for label 4, meaning the slowest speed of fan. If the 

jumper is placed over pin 1 and pin 2 for label F, the fan will 

spin at full speed. From label 1 to label 3, the fan speed 

decreases. If all of the pins are open (meaning no jumper is 

placed over the pins), the fan will not spin.

5.

  

Fan Speed Adjustment

You are able to adjust the speed of 120×120×25 mm cooling 

fan inside TurboBox Rac NA260A. To do so, pull the cooling 

fan out, and you will see five sets of jumpers labeled with 

F, 1, 2, 3, and 4 respectively from left to right on the board.

7.

  

Installation of Host Adapter and Cable 

     Connection

Before following the installation procedure, disconnect the 

server or workstation from power source to prevent electric 

shock or damage to add-on/graphics card.

6.

  

Switch of Gen1, Gen2 and Switch of 

      Power on/off by Host and Power on/off 

      by Manual

There are two switches labeled SW1-1 and SW1-2 respectively at 

the bottom side of the backplane of NA260A as shown in the 

following picture. SW1-1 manages setting of Gen1, Gen2 of PCI 

Express while SW1-2 controls setting of power on/off by host and 

power on/off by manual.

To switch PCI Express to Gen1, switch SW1-1 to “ON” position; to 

switch PCI Express to Gen2, switch SW1-1 to “OFF” position.

If you wish your NA260A to be powered on/off by host or server, 

switch SW1-2 to “ON” position. If you wish to power on/off your 

NA260A manually, switch SW1-2 to “OFF” position.

Power on the TurboBox Rac NA260A by pressing the power 

button for two seconds.

10.

  

Remove TurboBox Rac from Server or 

        Workstation

To remove TurboBox Rac NA260A from server or workstation, 

power off server or workstation first, and then power off 

TurboBox Rac.

11.

  

Verify Installation

9.

  

Power On Server or Workstation

In order to let the BIOS of server or workstation identify and 

assign resources appropriately, make sure to power on Netstor 

TurboBox Rac NA260A first, and then power on server or 

workstation. 

There is no software required for proper configuration of Netstor 

TurboBox Rac by server or workstation’s operating system; 

however, as a third party PCIe card is installed in TurboBox Rac, 

a request for the driver of the third party PCIe card will be 

prompted by the operating system. Please follow the instruction 

provided by the third party PCIe card.

When you want to verify a successful installation on Windows 

operating system, go to My Computer and right click the icon of 

My Computer. Select Manage from the menu (see figure 10-1), 

and click Device Manager in the left side of window of Computer 

Management (see figure 10-2).

PCIe ×8 cable

2. Connect the other end of PCIe ×8 

    cable to TurboBox Rac PCIe 2.0 ×8 

    host adapter on server or workstation.

1. Install Netstor TurboBox Rac PCIe 2.0 ×8 

    host adapter into an available PCIe ×8 

    connector (compatible with ×16 

    connector) in server or workstation. 

    Secure the host adapter with a screw.
