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
PCIe x8 Gen2 Host Cable Adapter 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 x8 adapter extends the PCIe bus at
40Gb/s with extremely low latency because there is no conversion software

2Hardware Requirements
The following steps will guide you through the installation of your HIB25-x8 Host and Target card.
2.1 Hardware & System Requirements
1. Computer / Server motherboard with x8 Gen2 PCIe slot
2. HIB25-x8-H, qty 1: Host card
3. HIB25-X8-T, qty 1: Target card
NOTE: The HIB25-x8 card works in pair (one as host card and other as target card)
4. One x8 iPass cable
5. OSS Expansion chassis with Gen2 backplane, or OSS expansion backplane and power supply.
2.1.1 HIB25-x8 card (Host and Target)
2.1.2 PCIe Slot & Motherboard Requirement
For Host Adapter card: Use a server-computer type motherboard that has a Gen3 or Gen2 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 host card and target card

One Stop Systems
OSS-PCIe-HIB25x8| 14
2.1.4 Gen3 Expansion Chassis / backplane
You need an expansion chassis with Gen2 or Gen3 backplane . Photos below are example of Gen3 OSS backplanes and an expansion unit.
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.
2.2 Software Requirement
1. Computer running Windows 7, 8, 10 and or Server
2. No driver is needed for the OSS-HIB25-x8

2Installation Procedures
2.1 Select Host and Target Card
Select the appropriate card to use, makes sure you have the correct host and target cards. Below are photos to help you
identify between Target and Host card.
2.2 Install HIB 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-X8 host card into the available PCIe slot in the computer motherboard. Use a x8 or x16 Gen2/Gen3 PCIe slot.
Secure the card

One Stop Systems
OSS-PCIe-HIB25x8| 16
2.3 Install HIB Target card
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.
The HIB Target card will only work in the OSS backplane designated “Upstream”slot. It will not function in the downstream
slot or the end-point slot of the backplane.
Install the Target card in the OSS expansion backplane. Plug-in the target card in the designated Upstream slot of the backplane.
Photos below are different backplanes showing where the location of the Upstream slot.

One Stop Systems
OSS-PCIe-HIB25x8| 17
2.5 Install PCIe card
Plug-in your 3rd party PCIe card in the expansion backplane. Use the downstream slot of the OSS backplane. See photos below.
2.6 Install link cable
Connect the PCIe iPass x8 cable between the host and target cards. Plug in the cable to the host card.
Plug in the other end of the cable to the target card. Make sure the cable is firmly latched in to the cable connectors of the card.
Photo below is a block diagram of an OSS expansion unit linked to a host server / computer.

OSS-PCIe-HIB25x8| 18
2.7 Connect ATX Power Supply
If you are using an expansion chassis, the power supply is already part of the unit. You can skip this step.
If you are using an expansion backplane, plug-in the ATX power supply cable into the 24pin ATX power connector on the OSS board
Connect power to the PSU and turn the switch to ON position.
2.8 Power ON the system
Turn On the main power of the host computer.
Start the computer by pushing the power button.
Upon powering ON the Host system, it will send a sideband signal to the Target card triggering the target expansion system to turn
ON.
If the expansion unit or the HIB card are not powering ON, check the link cable make sure it is firmly connected. The target and
host card must be fully seated in the PCIe slot in order to work correctly.

3 Verify Hardware
A operational host and target cards will have the following LEDs on the board illuminated.
1. PWR LED
2. x4 CBL and EDGE LEDs
3. x8 CBL and EDGE LEDs
3.1 LED Definition
PWR –Board has power
CBL –Signal detect on cable*
EDGE –Signal detect on card edge*
*Signal detect does not mean it has a link, but rather it identifies there is a signal on the card edge. If the link does not appear to be stable, it
could mean that there is a compliance pattern being generated by the PCIe device interfacing with this card.
If the board is operating on x4 mode, x4 CBL and EDGE are illuminated. This is indicative of a x4 slot PCIe slot (electrical) where the host or
target card is installed.
