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.

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 Card “is fully seated in the designated Upstream slot.

One Stop Systems
4U Value 5slot G3 Expansion Unit 18
2.4 Install Target Card
By default the “Target card (OSS-PCIe-HIB38-x16-T) ” or Expansion Interface card” is installed in the “Upstream slot” of the expansion
backplane. If the Target card is missing, install the target card in the “Upstream slot” (designated slot for Target card only).
Prior to installing the “Target card”, verify the Dipswitch SW1 is set to proper settings, see pictures below.
2.5 Install Host Interface Cards
The Host card (OSS-PCIe-HIB38-x16-H) is installed in a host computer's x16 slot .
Begin the installation by first powering down your computer.
Remove the power cord. 5VSB (5V Standby) is still available, if the power cord is still installed.
Use the procedures for shutting down your operating system and shutting off power to your computer provided in your owner’s
manual or system documentation.
The PCIe host card is a “half-height,” x16-capable PCIe card mounted to a “full-height” bracket as shown below.
Before installing the Host Interface card into PCIe slot, check the SW1 Dip switch is set to Host Mode, see picture below for correct settings.

One Stop Systems
4U Value 5slot G3 Expansion Unit 19
If Dipswitches are set correctly, insert the host card into a vacant x16 PCIe slot by gently pushing the card until it is firmly seated, then secure
the card to the slot with a mounting screw. See photos below.
Photo below shows the cable port on the back of the target card.
Low Profile Bracket Installation
For low profile case applications, change the mounting bracket to the low profile bracket. You can order a low profile bracket by contacting our
Sales Support. Replacing the “High Profile Bracket” with “Low Profile Bracket” is done by removing the screws that hold the card to the
bracket. Detach the standard bracket from the card, and place the low profile bracket and secure it. Use proper ESD procedures when
completing this action.

Place the riser card on a sturdy / solid surface.
Plug in the host card ( see photos below).
Reinstall the riser card back into the computer-mounting bracket / PCIe slot.
STOP
YOU MUST ONLY INSTALL THE PCIe HOST CARD INTO A PCI EXPRESS SLOT.
Only use cards WITH brackets. This will ensure that your PCIe host card can only be inserted into a PCIe slot. Although PCI
Express cards without brackets may fit into conventional PCI slots, you run the risk of damaging the PCI Express host card if
you insert it into a PCI slot. Please ensure that your host computer has PCI Express slots and install the host card only into a
PCI Express slot.
