Safety Instructions
Always use caution when servicing any electrical component. Before handling the expansion chassis, read the following instructions and safety
guidelines to prevent damage to the product and to ensure your own personal safety. Refer to the “Advisories” section for advisory
conventions used in this manual, including the distinction between Danger, Warning, Caution, Important, and Note.
Always use caution when handling/operating the computer. Only qualified, experienced, authorized electronics personnel should
access the interior of the computer and expansion chassis per UL and IEC 60950-1
The power supplies produce high voltages and energy hazards, which can cause bodily harm.
Use extreme caution when installing or removing components. Refer to the installation instructions in this manual for precautions
and procedures. If you have any questions, please contact Technical Support.
WARNING
Never modify or remove the radio frequency interference shielding from your workstation or expansion unit. To do so may
cause your installation to produce emissions that could interfere with other electronic equipment in the area of your
system.
When Working Inside a Computer
1. Before taking covers off a computer, perform the following steps:
2. Turn off the computer and any peripheral devices.
3. Disconnect the computer and peripheral power cords from their AC outlets or inlets in order to prevent electric shock or system
board damage.
In addition, take note of these safety guidelines when appropriate:
To help avoid possible damage to systems boards, wait five seconds after turning off the computer before removing a component,
removing a system board, or disconnecting a peripheral device from the computer.
When you disconnect a cable, pull on its connector or on its strain-relief loop, not on the cable itself. Some cables have a connector
with locking tabs. If you are disconnecting this type of cable, press in on the locking tabs before disconnecting the cable. As you pull
connectors apart, keep them evenly aligned to avoid bending any connector pins. Also, before connecting a cable, make sure both
connectors are correctly oriented and aligned.
CAUTION
Do not attempt to service the system yourself except as explained in this manual. Follow installation
instructions closely.

Protecting Against Electrostatic Discharge
Electrostatic Discharge (ESD) Warning
Electrostatic Discharge (ESD) is the enemy of semiconductor devices. You should always take precautions to eliminate any
electrostatic charge from your body and clothing before touching any semiconductor device or card by using an
electrostatic wrist strap and/or rubber mat.
Static electricity can harm system boards. Perform service at an ESD workstation and follow proper ESD procedures to reduce the risk of
damage to components. We strongly encourage you to follow proper ESD procedures, which can include wrist straps and smocks, when
servicing equipment.
You can also take the following steps to prevent damage from electrostatic discharge (ESD):
When unpacking a static-sensitive component from its shipping carton, do not remove the component’s anti-static packaging
material until you are ready to install the component in a computer. Just before unwrapping the anti-static packaging, be sure you
are at an ESD workstation or are grounded.
When transporting a sensitive component, first place it in an anti-static container or packaging.
Handle all sensitive components at an ESD workstation. If possible, use anti-static floor pads and workbench pads.
Handle components and boards with care. Do not touch the components or contacts on a board. Hold a board by its edges or by its
metal mounting bracket.

3 Installation Procedures
The following steps will guide you through the installation of your OSS-478 board, OSS-481 and M.2 modules.
3.1 Installation on CPCIe Host unit
Below is an example of a CPCIe host running Windows OS (i.e Windows 10)
3.2 Prepare the 0SS-478 board
Set the carrier board on a sturdy surface
3.3 Mount the M.2 CARD
Install the M.2 to JP1, JP2, JP3 and JP4 socket. Align the M.2 card to the slot and slowly push the card until it is fully seated.

One Stop Systems
OSS-CPCIe3-3U-CR-X | 15
Secure the M.2 card(s).
SKIP the instructions below if you do not have the mezzanine board (OSS-481). The OSS-481 is used to mount four more M.2 cards,
Place the OSS-481 mezzanine board on to a sturdy surface. Plug in each M.2 card to the slot (JP1, JP2, JP3 and JP4 socket). Secure the M.2 cards
with screws.
Attach the OSS-481 mezzanine board to the OSS-478 primary board.

One Stop Systems
OSS-CPCIe3-3U-CR-X | 16
Place the OSS-48I on top of the OSS-478 and carefully align the two mezzanine board connectors.
Lightly press the OSS-481 board down to the OSS-481 board until both boards are firmly mated together.
Turn the board and place the four screws to secure the OSS-481 board.

3.4 Install the CPCIe M.2 Flash Storage Module
Install the card carrier or CPCIe M.2 Flash Storage Module into the available slot of the CPCIe enclosure / chassis.
Slowly push the card carrier until it is correctly seated in the slot and secure it.
3.5 Connect Power and Power UP
Plug in the power to the CPCIe enclosure and power it UP. Upon powering UP the system, the OSS-478 bracket LEDs should come ON.
3.6 Verify Bracket LEDs
There are nine LEDs on the PXI bracket for 478. These are the Link LEDs for the 8748 PCIe switch.
The top four LEDs are for each of the M.2 links on the main board, 478.
The next four LEDs are for the M.2 links on the mezzanine board and the bottom LED is the upstream Link LED to the PXIe
backplane.
Solid green state means Gen3. Blinking green LEDs are Gen2 or Gen1 depending on the blink rate.
