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.
NOTE
Used to amplify or explain a comment related to procedural steps or text.
IMPORTANT
Used to indicate an important piece of information or special “tip” to help you
CAUTION
Used to indicate and prevent the following procedure or step from causing damage to the equipment.
WARNING
Used to indicate and prevent the following step from causing injury.
DANGER or STOP
Used to indicate and prevent the following step from causing serious injury or significant data loss
Disclaimer: We have attempted to identify most situations that may pose a danger, warning, or caution condition in this manual. However, the
company does not claim to have covered all situations that might require the use of a Caution, Warning, or Danger indicator.

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.

1 Introduction
The PCIe x16 Gen 2 cable adapter with no PCIe switch is a PCIe half-height add-in card with x16 cable external connectors on the slot cover.
PCIe cable adapters install easily into a computer's PCIe slot. A PCIe cable can then be plugged into the adapter to extend the PCIe bus from the
motherboard to an external device, like an expansion enclosure or storage device. The PCIe x16 adapter extends the PCIe bus at 80Gb/s with
extremely low latency because there is no conversion software.

2Hardware Requirements
This section provides information on the hardware and software requirements in order for the HIB25-x16 card to function / operate properly.
2.1 Hardware & System Requirements
1. Computer / Server motherboard with x16 Gen3 PCIe slot
2. HIB25-x16-H, qty 1: Host card
3. HIB25-x16-T, qty 1: Target card
NOTE: You need a pair of HIB25-x16, one as target card and the other as host card
4. One x16 iPass cable (connecting between host and target)
5. OSS Expansion chassis with Gen2 / Gen3 backplane, or OSS expansion backplane and power supply.
2.1.1 HIB25-x16 Host and Target Cards
You need a pair of HIB25-x16 card, one as host card and the other as target card.
2.1.2 PCIe Slot & Motherboard Requirement
For Host Adapter card: Use a server-computer type motherboard that has a Gen3 x16 PCIe slot in order for the card to operate to its max
performance. The Host adapter card is recommended to be installed in a x16 connector.
2.1.3 x16 iPass Cable
Use x16 iPass cable for connecting between host card and target card. Molex and Amphenol are two different brands of Ipass cable that are
supported.

One Stop Systems
OSS-PCIe-HIB25x16| 17
2.1.4 Expansion Chassis / backplanes
You need an expansion chassis with Gen3 or Gen3 backplane . Photos below are example of an OSS backplanes and an expansion unit. OSS
offers a multitude of expansion units and expansion backplanes, please visit our website to get further details on all products. Here is the web
link: https://www.onestopsystems.com
The HIB card has custom pin out that unique to OSS and only OSS Target adapters will work in the upstream slot of our
expansion backplanes.
2.1.5 ATX Power Supply
If you are using an OSS backplane with the HIB38-x8-DUAL card, you need a power supply unit to provide power. A standard ATX power supply
will work with the boards.
2.2 Software Requirement
1. Computer running Windows 7, 8, 10 and or Server
2. No driver is needed

3Installation Procedures
3.1 Check HBA cards to use
Prior to using the cards, you need to make sure you have the appropriate host and target cards.
The OSS HIB25-x16 host card does not have an optocouplers mounted on the board, see photo below.
The OSS HIB25-x15 target card is populated with four optocouplers on the boards, see photo below.
3.2 Install Host card
Power down the host computer first before installing the host card. Do not install the host card while the computer is ON.
Install the HIB25-x16 card into the available PCIe slot in the computer’s motherboard. Use a x16 Gen3 PCIe slot.
Make sure to secure the card with a screw.

One Stop Systems
OSS-PCIe-HIB25x16| 19
3.3 Install Target card
Install the Target card in the OSS expansion backplane. Plug-in the target card in the “Upstream” slot.
Do not plug in the target card while expansion unit or the expansion backplane is ON as this can damage the board. Turn OFF the
unit first before installing the card.
Photos below are some of the different backplanes showing where the locations of the “Upstream” slot.

One Stop Systems
OSS-PCIe-HIB25x16| 20
3.4 Install PCIe card
Plug-in your third party PCIe card in the expansion backplane. Use the downstream slot on the OSS backplane. See photos below for the
location of the downstream slot / end-point slot.
3.5 Install x8 iPass cable
Attach the cable by first pulling back on the retractor ring or pressing the metal tab with the keyed slot aligned with the connector
key ridge on the slot cover, insert the cable connector into the connector shell on the board until the connector teeth snap securely
into the holes in the cable shell.
The connectors on either end of the PCIe x8 cable are identical. Each connector is equipped with a retractor to allow the connector
to be locked into place.
