Slot 1 :
Thunderbolt 3 target card (already fixed in the chassis)
Slot 2 : PCIe x8 slot (open-type; supports PCIe card x16/x8/x4/x1)
Slot 3 : PCIe x8 slot (closed-type; supports PCIe card x8/x4/x1)
Slot 4 : PCIe x8 slot (open-type; supports PCIe card x16/x8/x4/x1)
Before proceeding to installation procedure, disconnect the NA211TB3 from
power source for prevention of electric shock or damage to PCIe add-on card.

2. Three PCIe slots at rear panel of NA211TB3 are pre-covered by removable
L-shape metal brackets. Loosen the screw of the removable L-shape metal
bracket for the PCIe add-on cards installation.
3. Insert PCIe add-on cards in the proper PCIe slots within the enclosure and
tighten them with screws on PCIe add-on cards’ brackets.
4. Put the top cover back to enclosure and tighten and thumbscrew.

6. Fan Speed Adjustment
To adjust the fan speed of 8x8 cm cooler on NA211TB3, pull the fan cooler
module out. Above cooler’s connector, there are four sets of jumpers labeled
6V, 8V, 10V, 12V from top to bottom. The default setting is jumper being
placed over pin 7 and pin 8 for 6V for medium fan speed. The fan speed
increases from 6V to 12V (12V: full speed). If all pins are open (no jumper
placed over pins), the fan will not spin.

1. Connect NA211TB3 chassis with power source, and then connect Netstor
chassis and Thunderbolt computer with Thunderbolt 3 cable.
2. The NA211TB3 enclosure is designed to be powered on/off simultaneously with
Thunderbolt host computer when Netstor unit is connected to computer by
Thunderbolt cable. Therefore, power on computer first, and then Netstor unit
will be powered on automatically.
(NA211TB3 also supports hot-plug and hot-unplug for powering on and off)
3. Verify Netstor Thunderbolt 3 target card is recognized by computer. Click the
Apple icon on top left of the screen, select About This Mac, and click System
Report, and then System Information pane will pop up. Select Thunderbolt at
the left side of the pane; if NA211TB3 can be selected to see its information,
the Netstor Thunderbolt 3 target card is recognized correctly by computer.

4. Verify the PCIe cards installed in NA211TB3. After the verification of Netstor
Thunderbolt 3 target card, click PCI at the left side of the pane, and all the
PCIe cards installed in NA211TB3 will be shown in the information area
within the pane.

5. Verify the drivers of PCIe cards are installed on macOS. When seeing all the
PCIe cards are listed at the last step, there will be a section Driver Installed
indicating the status of PCIe cards’ drivers. If it shows “No” for the status, find
and install the Thunderbolt-aware driver for the PCIe card, and then the status
will become “Yes” to mean the driver of the PCIe card is installed properly.
6. While NA211TB3 is connected to host computer by Thunderbolt cable, when
shutting down computer, the Netstor unit will be shut down simultaneously
as well.
