1. The PCIe slot of host PC, workstation or Mac Pro that
links with NA255A must be identified first for correct
connection between host and NA255A. Four conditions
A, B, C, and D for connection are listed below:
NA255A
External PCIe 3.0 to GPU Desktop Enclosure
(A)
If the PCIe slot of host PC, workstation that works with NA255A
is PCIe 3.0 ×16,
set (this is the default setting)
JP2 at Gen3.
SW1-2 at ON.
(B)
For Mac Pro, host PC, or workstation whose PCIe slot is
PCIe 2.0 ×16 that is used to work with NA255A,
set
(D)
If the PCIe slot of host PC, workstation that works with
NA255A is PCIe 2.0 ×8,
set
After identifying the PCIe slot in computer that
links with NA255A and making the correct
setting as one of the four conditions listed
above, install the host card NP970A-H onto
the PCIe slot in host PC, workstation or
Mac Pro.
(C)
If the PCIe slot of host PC, workstation that works with
NA255A is PCIe 3.0 ×8,
set
6. Connect one end of two PCIe ×8 data cables to PCIe ×8
connectors on rear of NA255A.
7. Connect the other end of two PCIe ×8 data cables to the
two PCIe ×8 connectors on NP970A-H host card on
host PC, workstation, or Mac Pro.
5.
Fan Speed Adjustment
The fan speed of the front 120×120×25 mm cooling fan of
NA255A can be adjusted. Pull out the fan module, on the
connector of cooling fan, there are five sets of jumpers labeled
with 4, 3, 2, 1 and F from top to bottom on the fan connector
board. The default setting is the jumper being placed over pin 9
and 10 for label 4 for slowest speed. The speed increases from
label 3 to label F. When jumper is not placed over pins, the fan
will not spin.
6.
Powering On/Off TurboBox NA255A
There are two ways to power on/off the NA255A. One is to
power on/off NA255A by host (the default setting); the other is
to power on/off NA255A by manual. Configure switch SW1-1
near slot 5 on backplane for setting. For powering on/off by host,
switch SW1-1 to “ON” position. For powering on/off by manual,
switch SW1-1 to “OFF” position.
When NA255A is set for powering on/off by host, the NA255A
will be automatically powered on and off with the host computer.
When NA255A is set for powering on/off by manual, the standard
powering on/off procedure below must be followed:
(1) Power on TurboBox NA255A by pressing
the power button for two seconds until
the button shows blue light.
(2) In order to let the BIOS of host PC, workstation, or Mac Pro
identify and assign resources appropriately, always power
on NA255A first, and then power on host PC, workstation,
or Mac Pro.
(3) To remove TurboBox NA255A from host PC, workstation,
or Mac Pro, power off host PC, workstation, or Mac Pro first,
and then power off NA255A.
3. Remove the L shape metal bracket on rear of TurboBox
NA255A by unscrewing the screw of metal bracket for
installing the graphics or PCIe card on NA255A.
4. Install one graphics/PCIe card into one PCIe ×16 slot in
NA255A and tighten it with a screw.
5. Put the side door back to TurboBox NA255A, and tighten
the two thumbscrews to fasten the side door.
Each GPU card in NA255A is provided with two 6+2 pin
PCIe power cables for extra power resource. Up to
4 double-width, full-length GPU cards can be installed in
slot 2, slot 3, slot 4, and slot 5 in enclosure.
2. Loosen the two thumbscrews and remove the side door from
TurboBox NA255A.
8. Connect the end of power cord to power receptacle on
TurboBox NA255A and the other end of power cord to
grounded outlet or power strip.
There are two hot-swappable 120×120×25 mm cooling fans
for ventilation inside TurboBox NA255A. The cooling fans
can be simply drawn out by pulling the L type metal handle
on the fan modules.
Note:
Make straight connection between host card and target
card with mark ×8 to ×8, and ×16 to ×16. DO NOT make
cross connection.
