Preface
Advisories
Five types of advisories are used throughout this manual to provide helpful information, or to alert you to the potential for hardware damage
or personal injury.
Disclaimer: We have attempted to identify most situations that may pose a danger, warning, or caution condition in this manual. However, One
Stop Systems does not claim to have covered all situations that might require the use of a Caution, Warning, or Danger indicator.

One Stop Systems
OSS-PCIe4-4UV-5 7
Safety Instructions
Always use caution when servicing any electrical component. Before handling the One Stop Systems 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.
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
Before taking covers off a computer, perform the following steps:
Turn off the computer and any peripheral devices.
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. One Stop Systems strongly encourages 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.

1 Introduction
1.1 General Specifications
This 5-slot rackmount expansion platform provides PCIE expansion at a value price. The 4UV supports ONE PCIe 4.0 x16 host connection to 5
PCIe 4.0 x16 slots from 1m to 2m away from the host server. The system supports 5 full-length PCIe add-in cards (AICs) such as GPU card,
NVME flash and industrial I/O. Two fan choices allow for high-power add-in card cooling up to 100W per AIC or a set-and-forget manual speed
control using PWM fans when lower power AICs operation are required. Two 2000W power supplies provide redundant hot-swap system
power.

2 Hardware Set-up / Installation
The following steps will guide you through the installation of your One Stop Systems expansion system
CAUTION
Hardware installation shall be performed only by qualified service personnel per UL and IEC 60950-1.
Electrostatic Discharge (ESD) Warning
All PCI cards are susceptible to electrostatic discharge. When moving PCI cards, it is best to carry the cards in anti-static
packaging. If you need to set a PCIe card down, be sure to place it inside or on top of an anti-static surface. For more
information, see “Protecting Against Electrostatic Discharge” in the Preface.
WARNING
High voltages are present inside the expansion chassis when the unit’s power cord is plugged into an electrical outlet.
Disconnect the power cord from the AC outlet before removing the enclosure cover. Turning the system power off at the
power on/off switch does not remove power to components. High voltage is still present.
CAUTION
Before touching anything inside the enclosure, move to an ESD station and follow proper ESD procedures. Failure to do so
may result in electrostatic discharge, damaging the computer or its components. For more information, see “Protecting
Against Electrostatic Discharge” in the Preface.
2.1 Installation-Procedures Overview
Below is the concise version on how to set up the 4U Value GPU Accelerator System.
1. Open Enclosure: Section 2
2. Target Card Installation (If not installed): Section 2
3. Host Card Installation: Section 2
4. Link Cablse Installation: Section 2
5. Connecting Power: Section 3
6. Powering UP the Systems: Section 3
7. Hardware Check: Section 4
8. Re-install Top Cover: Section 4.3
9. Verify Installation (via Operating System): Section 6
10. GPU card or PCIe card Installation: Section 8
11. GPU or PCIe card Check or Verification: Section 9
When installing 3rd Party PCIe card, start with one card first to determine if there are any software and hardware issues or incompatibility
problems that may occur. This will help you in troubleshooting the problem more easily and efficiently. If everything works well and no
configuration issues, you can proceed with the installation of the remaining 3rd party PCIe cards.
Always refer to or read “3rd party manufacturer installation guide” for further instructions.

2.2 Before you Begin
The system’s power supply is auto-switching, it will automatically switch to match whatever source power you are using. The product is shipped
with a US/Canadian Standard, 125V or 250V power cord.
2.3 Remove Top Cover
Remove the five (5)mounting screws on top of the chassis. Slide the enclosure cover towards the front of the unit to disengage it from the
guides until it clears the back hold-down, and then lift the cover off.
Check inside the unit; make sure the “Target Adapter Card “is fully seated in the Upstream slot.

One Stop Systems
OSS-PCIe4-4UV-5 20
2.4 Install Target Card
By default the “Target card (OSS-PCIe-HIB616-x16)”is installed in the target slot / upstream slot of the expansion system.
Check the switches on the Target card, make sure it is configured to Target mode.See photo below for the Target mode switch
settings.
2.5 Install Host Card
Before installation, you must check the switches on the Host card. By default, all the switches on the Host card are set to OFF position (“Auto-
Negotiation” mode). You can leave the switches to default or manually set the switches (SW1 and SW2) on the card for the desired Host
operating mode. See “Host Card Configuration” section for more details. See photos below for host mode switch settings.
2.5.1 Host Card Configuration
By default, the Host adapter card is set to “Auto-Negotiation” mode. All switches are set to OFF position. The following are manual switch
settings on the Host card.
x16 Dip switch Settings:
SW1 #2 = ON; #5 =ON.
SW2 #1 = ON; #2 = ON
