1 Overview
1.1 Description
The OSS target backplane supports a PCIe Gen3 target cable adapter installed in the OSS target slot and one PCIe x16 expansion card installed in
the expansion / downstream slot. The slots are backward compatible and support Gen 1 and Gen 2 target adapters and expansion cards. Only
target adapters with the OSS target slot configuration are supported. Expansion cards designed to the PCIe PCI-SIG specification are supported.
While the backplane is used in the CUBE products, it can also be used in test applications as a stand-alone backplane with 12VDC power
applied.
1.2 Features
1.2.1 Backplane
The backplane has two slots
o 1slot is Target slot (a.k.a “Upstream slot / port”). This is a designated slot for the target adapter card
o 2nd slot is the expansion slot (a.k.a “Downstream" slot / port). Use this slot to plug in a specific PCIe card. The
downstream slot accommodates a single x2, x4, x8 and x16 PCIe card.
o The slot is backward compatible and support Gen 1 and Gen2
Target slot is x16 Gen 3
Expansion slot is x16 Gen 3
12 VDC input
1.2.2 Adapter Cards
There are different types of cable adapter cards to use with the backplane. It is recommended to use a compatible OSS cable
adapter card.
The Host adapter card inserts into any x16 slot on the host motherboard.
The Target adapter card operates ONLY in the OSS backplane target slot.
Support half-height bracket.
The Host and Target cable adapter cards require no software / drivers.

2.2.4 Host Adapter Card
The Host card can only be installed in the computer motherboard of a host computer.
2.2.5 Target cable adapter card
The target adapter card inserts into the designated target slot (Upstream slot) on the OSS expansion backplane. Do not plug in the target card
in the “Downstream slot” on the expansion backplane.

3 Installation Instructions
3.1 Install Host Card
Insert the host cable adapter into an appropriate PCIe slot of the host computer. For example, a PCIe x4 host board can be inserted into a PCIe
x16, x8, or x4 slot. It will still operate at x4 speeds. If you are using a x16 Gen3 cable adapter, use a x16 PCIe slot on the computer’s
motherboard. Secure the cable adapter card
3.2 Install Target Card
Insert the target cable adapter card into the PCIe slot (this is the designated slot). The target slot is also known as “Upstream slot”, see photos
below. The Target card will only operate in the Target slot / Upstream slot.
Photos below are few examples of x4 and x16 target cards being installed in the Target slot (also known as Upstream slot).

x16 card installed in the target slot

NOTE: Do not use the Endpoint slot (Expansion slot / Downstream slot) for the “Target Cable Adapter card”.
3.3 Plug in Add-in Card / 3
Plug in the add-in card or PCIe card in the available IO slot (Endpoint slot: also known as expansion slot and / or downstream slot), see photos
below.
rd
Party PCIe card
Carefully plug in the add-in card or your 3rd party PCIe card (i.e. Ethernet card, Storage card, Video card, Sound Card and etc) in the downstream
slot.

3.4 Connect Power
Connect +12v 4-PIN Aux power cable from your ATX power supply to either J3, J5 or both J3 and J5, see photos below.
If your ATX power supply does not have a separate +12V 4-pin connector, you can buy a P4-to-ATX Power Supply adapter, see photo below.
This cable is not sold by OSS. You can buy this from any online electronics stores. Use the description “P4-to-ATX Power Supply adapter” when
searching for the adapter cable on the web.

3.5 Connect Link Cable
Connect the link cable between Target and Host cards. You can also use a x8 or x16 iPass or PCIe 3.0 cable, depending on the cable adapter
cards you are using.
3.5.1 Connecting x4 Ipass Cable
3.5.2 Connecting x16 iPass Cable

3.5.3 Connecting PCIe 3.0 Cables
For more detail on how to properly connect the PCIe 3.0 cables, please read the manual for the HIB68x16 card.
3.6 Power Up the System
Connect external power brick to the 2-slot backplane. The board LED will turn ON (as solid red). The board is at standby-mode.
Power up the Host computer. It will instantly power up the Target card and the backplane (the red LED will turn OFF).
Link between the host and target will be established after the host computer is powered UP. For details and information on the LINK
led for each cable adapter cards, please read the assigned manual for the cable adapter card.
3.7 Using any Third-party I/O device
The add-in card or third-party I/O device must be installed in the endpoint slot (expansion slot / downstream port).
Connect the external power source (separate from the host system power supply) to the add-in card or PCIe card device if
necessary.
3.8 Force Power ON
Install shunt or jumper on J1 connector to force power on the backplane. This is not required for normal operation.

MODE
LED Indicator / Description
Standby
Controller is in the OFF condition, but it is not clear what the LED signal state is in the OFF condition. Since the LED is
powered by 12V input power (not controlled by PS_ON), the LED may shine in this state.
Operational
Controller is in ON condition and power supplies are within specified limits. The LED will be OFF.
Malfunction
If output power is not within specified limits, then LED will shine RED. Or the target board is not initialized
