1 Overview
1.1.1 Description
The PCIe x4 Gen 2 expansion kit is used to extend the PCI express bus from a host server to an external expansion chassis. The host adapter
card installs into a PCIe x4, x8, or x16 slot of the server mother board. It then cables to a downstream expansion board and installs in the SHB
slot of the backplane and provides primary fan-out switch to support multiple configurations of PCI express expansion slots.
The host adapter installs in the PCIe x4, x8, or x16 slot of the host motherboard. The target adapter card installs in the appropriate slot of the 2-
slot backplane. A third party I/O card installs in the second slot of the 2-slot backplane. The I/O card then appears to the host system as host of
that system.
Gen 2 products operate at 5Gb/s per lane, or twice the bandwidth of Gen 1 products. Therefore, PCIe x4 Gen 2 products operate at 20Gb/s
when inserted in a x4 or higher slot. .

2Component Identification
2.1.1 Host cable adapter card
The PCIe x4 expansion kit contains two cable adapter boards, the host cable adapter and the target cable adapter. The host adapter inserts into
the host computer’s PCIe x4, x8 or x16 slot.
Cable LED indicators are the same for both Host and Target configurations.
2.1.2 Expansion Link Board
The expansion link board installs in the extending or system PCIe goes to all available slots on the expansion backplane and can control multiple
configurations of PCIe expansion slots.

3Installation Instructions
3.1.1 Installing the Adapter Kit
1. 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. Secure the cable adapter card
3.1.2 Expansion link board
1. Insert the expansion link board into the SHB slot on the chosen backplane.
2. Connect the x4 PCIe cable to both cables adapter cards. Press the green TAB while slowly inserting the cable, then release it to lock
the cable. See photo below.
3. If you have the cable with a green Pull-Tab design, pull the tab to lift the prongs that insert in the holes on the PCIe connector. Push
in the connector. Release green thumb tab insuring that the prongs are fully engaged in the mating connector. See photo below.
4. Test by pulling back on the connector
4Operation
1. Plug in expansion system and turn the power supply on.
2. Power up host computer.
3. The expansion system will power up.

5Technical Information
The transmit and receive signals on the OSS-HIB-25x4 are driven and conditioned by Pericom redriver chips. Adjustments can be made to
equalization, de-emphasis and output swing. These controls are factory set by the use of zero Ohm resistors.
In the following tables, a 0 indicates that a zero Ohm resistor has been installed and a 1 indicates no resistor. In rare cases, mostly where non-
OSS equipment is used with the HIB-25x4, these adjustments may need to be changed. The following tables are made available for this
purpose. It is highly recommended to contact OSS customer support before making changes to these settings. Having the customer solder to
the board should void the warranty.
5.1.1 Signal Adjustment
5.1.2 Pin Assignments
Host and Target card connectors (x4 Card Edge Connector)
The pins are numbered as shown with side A on the top of the centerline on the solder side of the board and side B on the bottom of
the centerline on the component side of the board.
The PCIe interface pins PETpx, PETnx, PERpx, and PERnx are named with the following convention: “PE” stands for PCIe high speed,
“T” for Transmitter, “R” for Receiver, “p” for positive (+), and “n” for negative (-).
Note that adjacent differential pairs are separated by two ground pins to manage the connector crosstalk.

Notes:
1. Optional signals that are not implemented are left as no connects on the board side connector.
2. Reserved signals are no connects on the board side connector.
3. Although support of CWAKE# is optional from the board side connector perspective, an allocated wire is mandated for the cable
assembly.
4. Board side pin-outs on both sides of the Link are identical. The cable assembly incorporates a null modem for the PCIe transmit and
receive pairs.

6 Returning Merchandise to One Stop Systems
If factory service is required, you must contact OSS Service Representative to obtain a Return Merchandise Authorization (RMA) number. Put
this number and your return address on the shipping label when you return the item(s) for service. One Stop Systems will return any product
that is not accompanied by an RMA number. Please note that One Stop Systems WILL NOT accept COD packages, so be sure to return the
product freight and duties-paid.
Ship the well-packaged product to the address below:
RMA # ________
One Stop Systems
2235 Enterprise Street, Suite#110 92029
USA
It is not required, though highly recommended, that you keep the packaging from the original shipment of your One Stop Systems product.
However, if you return a product to One Stop Systems for warranty repair/ replacement or take advantage of the 30-day money back
guarantee, you will need to package the product in a manner similar to the manner in which it was received from our plant. One Stop Systems
cannot be responsible for any physical damage to the product or component pieces of the product (such as the host or expansion interfaces for
the PCIe expansion chassis) that are damaged due to inadequate packing. Physical damage sustained in such a situation will be repaired at the
owner’s expense in accordance with Out of Warranty Procedures. Please, protect your investment, a bit more padding in a good box will go a
long way to insuring the device is returned to use in the same condition you shipped it in. Please call for an RMA number first.
