Unpacking Instructions
1. If the carton is damaged when you receive it, request that the carrier's agent be present when you unpack and inspect
the equipment.
2. After unpacking, verify that all items listed in the packing list are present.
3. Inspect the equipment for shipping damage.
4. Save all packing material for storage or return shipment of the equipment.
5. For repairs or replacement of equipment damaged during shipment, contact One Stop Systems, Inc. to obtain a
Return Materials Authorization (RMA) number and further shipping instructions.
Installation and Removal
1. Power down the host system.
2. Open the chassis according to your system documentation.
3. Let the power supply cool down, if necessary.
4. Remove the Host Cable Adapter from the protective bag, observing proper ESD safety procedures.
Installing the Host Cable Adapter:
1. Insert the Host Cable Adapter into a PCIe x4, x8 or x161add-in card slot. Make sure that the card is well seated and
tighten the screw.

1“Up-plugging” the Target Cable Adapter into a x8 or x16 slot is allowed, but the motherboard manufacture may limit the bandwidth to x1 (250MB/s)
speeds. If you need to do this, check with the motherboard manufacturer to see how up-plugging is handled on their motherboards. A PCIe x4 board
will not physically fit in a x1 slot.

2. Attach the cable by first pulling back on the retractor ring. With the keyed slot aligned with the connector key ridge on
the slot cover, insert the cable connector into the cable port connector on the board until the cable locks in place.
3. The connectors on either end of the PCIe x4 cable are identical. Each connector is equipped with a retractor to allow
the connector to be locked into place.

4. Attach the other end of the cable to the upstream port connector of the ELB in the expansion enclosure. To link to a
second expansion enclosure, connect a second cable from the downstream port connector on the ELB of the first
expansion enclosure to the upstream port connector on the ELB of the second enclosure.
Removing the Host Cable Adapter:
1. Remove the cable by pulling on the green retractor ring which releases the locking mechanism.
2. Loosen and remove the screw before removing the Host Cable Adapter from the card slot.

Connectors
PCIe 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.

OSS-EBP-2000 Backplane
The OSS-EBP-2000 has two PCI Express x8 link slots connected together. One
slot supports the OSS-PCIe-HIB2-x4-T that brings a remote PCIe bus to the
backplane via a cable interface. Any x8, x4, or x1 IO PCIe add-in board can be
installed in the second slot and operate as a remote slot from the host PC. For
example, the One Stop Systems quad USB board can be installed in the
second slot allowing four USB devices to be operated from the remote
computer.
