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 around 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 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.

1.2 Overview of HIB616-x16
1.2.1 x4 cable Ports
There are four x4 cable ports available on the HIB / HBA card. It is very important to know where port#0 is when connecting a single x4 PCIe
SFF-8644 cable. Port #0 is the connector nearest the Link LEDs. A single x4 SFF-8644 cable must be inserted into port#0 of the Target card all
the time. For the Host card, you can plug in a single x4 cable to any port if the Host card switch is set to operate in a x4 mode.
When using two x4 SFF-8644 cables, it must be connected to port#0 and port#1 of the Target card only. For the Host card, you can plug-in the
two cables to port#0 and portt#1 OR port#2 and port#3.
Below are photos of the HIB cards in a different position when plugged into a PCIe slot. This will serve as a guide in determining the location of
PORT 0.

2.6 Supported Use Cases
Using a pair of OSS-PCIe-HIB616-x16 card (Target and Host cards), OSS Gen4 backplane and PCIe Gen4 cables.
2.7 Not Supported Setup
2.7.1 Host-to-Host
This configuration is NOT supported. The OSS-518 board (HIB616-x16card) is not programmed for this option, nor will it work from hardware
standpoint.
2.7.2 Using 3rd Party Target Backplane
This is not supported. However, this configuration may work with appropriate switch confirmation. The OSS- 518 cards typically outputs
REFCLK on pins A6 and A7 which is not PCI standard. This can be changed by using the OSS switch (SW1-4). The OSS-518 outputs POWER_ON
signal on a Reserved PCI pin. If customer expects remote turn ON, then they need to add that to their backplane, otherwise, they need to turn
on the backplane power (not just AUX) before powering on host. Not guaranteed to work.
.
2.7.3 Connecting to 3rd Party backplane via on-board SFF-8644 connector.
This is not supported. But it may work as long as the 3rd party backplane creates its own REFCLK, Reset and is powered on first. If issue arises,
customer is responsible for troubleshooting their non-OSS / 3rd party backplane. Not guaranteed to work.

3 Installation Procedures
The following steps will guide you through the installation of your OSS HIB616-x16 card.
3.1 Tools Required for Installation
To complete the installation of the OSS product you will need a Phillips-head screwdriver and ESD wrist strap to prevent electrostatic discharge.
3.2 Configure Cards (Host and Target modes)
Set the switches on the card for the desired operating mode. See Host and Target cards configuration section for more details.
Photos below are Host and Target mode settings.
•The Host card is installed in the host computer.
•The Target card is installed in the expansion OSS backplane. The card must be installed in a target slot.
3.3 Install the Target card
In this example, install the Target card in a Gen4 OSS backplane.
Do not plug in the Target card while the board or the unit is ON or has power. Disconnect the power first prior to installing the
card.

One Stop Systems
HIB616x16 (Rev B) |20
Plugin the Target card in the x16 PCIe upstream slot / target slot on the expansion board.
Note: Do not plug a Target-configured card in a downstream slot. The Target card will not function in a downstream slot and
may cause damage.
Secure the card by screwing the card-bracket to the chassis.
3.4 Install the Host card
Install a Host-configured card in a x16 Gen4 PCIe slot of a motherboard.
•Check the PCIe slot for any foreign debris as this can damage the card during installation.
•Align the host card PCIe connector on top of the PCIe slot and carefully push the card down until it is firmly seated.
Do not plug in the Host card while the board or the unit is ON or has power. Disconnect the power first prior to installing the
card.
Secure the card!
