OSS-KIT-EXP-6002 Host Server to Expansion System Kit User Manual

OSS-KIT-EXP-6002 Host Server to Expansion System Kit

Overview

Description
The PCIe x4 expansion kit is used to extend the PCI express bus from a host server to an external expansion chassis. The host adapter card inserts into a PCIe slot of the server. It then cables to a downstream expansion link board (ELB). The ELB acts as a downstream cable link board and the primary fan-out switch to support multiple configurations of PCI express expansion slots. The host adapter installs into a PCIe x4, x8 or x16 slot on the host motherboard. It then cables to the expansion link board and installs in the SHB or system slot of a CPCIe backplane.

Component Identification

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.

Expansion Link Board
The Expansion Link Board (ELB) OSS-CPCIe3-3U/6U-ELB-x4 is a downstream link board that installs into a CPCIe chassis. The ELB fits into the system slot of a CPCIe backplane. The ELB is the downstream link board and the primary fan- out switch to support multiple configurations of CPCI or CPCIe expansion slots.

Installation Instructions

Installing the Adapter Kit
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

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 or pull the green TAB while slowly inserting the cable, then release it to lock the cable. See photos below
3. Test by pulling back on the connector.

Removing PCIe Cable
To remove the cable, press or pull the green tab and slowly pull the cable out.

Operation

1. Plug in expansion system and turn the power supply on.
2. Power up host computer.
3. The expansion system will power up.

Technical Information

The transmit and receive signals on the OSS-HIB-25×4 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-25×4, 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.

Signal Adjustment

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 Board side pin-outs on both sides of the Link are identical. The cable assembly incorporates a null modem for the PCIe transmit and

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.
