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 in the area of 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 in order 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.

Hardware Requirements

The following steps will guide you through the installation of your OSS-PCIe- ECA-x8-G3 board.

CAUTION
Before touching anything inside the enclosure, move to an ESD station and follow proper ESD procedures. Failure to do so may result in electrostatic discharge, damaging the computer or its components. For more information, see “Protecting Against Electrostatic Discharge” in the Preface.

Hardware & System Requirements
You need the following hardware when setting up the OSS-PCIE-ECA-X8-G3

1. OSS x8 Host Adapter Card (Model: OSS-PCIe-HIB25-x8)
2. One OSS x8 iPass cable
3. ATX Power Supply (with 24pin connector)
4. Gen3 x16 PCIe slot (computer motherboard)

OSS-PCIe-HIB25-x8

A x8 host adapter card is needed in order to connect the OSS-PCIE-ECA-X8-G3 to the host computer. It is strictly recommended to use the appropriate OSS host adapter card to achieve proper operation. See photo below of the OSS-PCIe- HIB25-x8 card to use.

x8 iPass Cable

Use x8 iPass cable for connecting creating a link between host card and OSS- PCIE-ECA-X8-G3

ATX Power Supply (24pin Connector)

Standard ATX 24-pin Power Supply (i.e. 500 Watt PSU)

PCIe Slot & Motherboard Requirement
For Host Adapter card: Use a server-computer type motherboard that has a Gen3 or Gen2 x16 PCIe slot in order for the card to operate to its max performance. The Host adapter card is recommended to be installed in a x16 connector.

Installation-Procedure

Configuration / Setup
The diagram or drawing below shows how to setup and use the hardware.

The OSS-PCIe-ECA-x8G3 supports x1,x4,x8 and x16 PCIe cards as long as the PRSNT is implemented properly on the installed PCIe card, see section 5.3 (PCIe Connector Pin outs).

• On the ECA board, the PRSNT2 x1, x4, x8 and x16 are all connected together. So as long as the PCIe card being plugged-in connects PRSNT1 to any PRSNT2 pin then the redriver will be enabled and its code downloaded from EEPROM.

Install Host Adapter Card
Plug-in the card to the PCIe slot of the host computer’s motherboard. Make sure to install in a PCIe x16 or x8 Gen2 or Gen3 slot and the slot. Ensure the card is well seated and secure with the screw.

Connect the x8 Cable
Use a x8-to-x8 Ipass cable. 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 connector shell on the board until the connector teeth snap securely into the holes in the cable shell.
Connect the cable to the ECA-X8 board

Connect the other end of the cable to the host adapter card.

Disconnecting x8 Cable
To remove the cable, pull down the green plastic tab and slowly pull the cable out

Install PCIe card
Plug in the add-in card or PCIe card into the available IO x16 slot (Endpoint slot: also known as expansion slot and / or downstream slot) of the ECA-X8 board.

Connect ATX Power Supply
Plug-in the ATX power supply cable into the 24pin ATX power connector on the ECA board
Note: Sometimes an external load is necessary for ATX power supplies to regulate properly. (i.e. connecting hard drive power).

Connect power to the PSU and turn the switch to ON position. The “3AUX GOOD” LED comes ON.

Turn ON the Host Computer
Turn ON the host computer / server. Two “bracket LEDs” will illuminate as solid green.

Powering UP the ECA board
The ECA expansion board is switched ON remotely by the Host computer.

• A Power ON / Sideband signal is sent from the cable upon turning ON the host, triggering the ECA expansion board to Power ON.
  When using a different brand or a non-OSS host adapter card and a non-OSS cable, the sideband signals may not operate properly which can cause the ECA board not to initialize and generate power and link failures.

• The ECA expansion board will turn ON automatically upon powering UP the computer and it will power OFF when the computer is shutdown.

• Verify Hardware
  To verify a working hardware, check the LEDs on the “host card” and “ECA board”. A working ECA board will have three solid Green LEDs. The 3AUX GOOD LED will illuminate as solid green.

ECA board LEDs
Power LED and Cable Present LED are ON (as solid green)

Host Card LEDs
A fully linked and functional Host card will have 5 solid green LEDs, see photos below.

• PWR LED: When “ON” indicates the board is powered UP.
• CBL LED: Cable is present / detected
• EDGE LED: This indicates that there is a link between the HIB and device connected to the card edge. This is typically a server or a switch on an expansion chassis. A solid light indicates that it is linked at the maximum speed possible. Blinking light indicates that it is linked a slower rates.

• If only x4 CBL and EDGE LEDs are illuminated, this indicates that you are linking up to x4 only.
• To achieve a x8 link, you must use (highly recommended) an OSS x8 Ipass cable and an OSS HIB25-x8 adapter card.

Identify ECA Device

The host card and ECA board are both transparent to the system. The system will only detects the third party PCIe card that is plugged-in to the x16 slot of the ECA board.

Board and cable are only x8, it will only Link to x8, not a x16 link.

• If you are using a x8-x4 cable (one side of the cable is connected to x4), you’ll have a x4 Link, x8 Link will not work.
• If you are not using an OSS product (cable or adapter card) , the sideband signals will not provide proper operation.

Software Installation

No software or driver is required for the Host Adapter card and for the ECA board.

Additional Technical Information

Connectors and LED Indicators

Power Connector Pin Outs
Standard ATX 24-pin power connector pin outs

PCIe Connector Pin outs
Table below shows the pin out definition for the x1, x4, x8, and x16 PCI Express connectors. The auxiliary pins are identified in the shaded areas. For further details on Card edge connector pin outs see PCI Express CEM Specification, Revision 3.0, pages 83-86 Based on the information presented below, the PRSNT2 x1, x4 x8 and x16 are all connected together.

• So as log as the PCIe card / board being plugged-in connects PRSNT1 to any PRSNT2 pin then the redriver will be enabled and its code downloaded from EEPROM.
• Generally, this means all types of PCIE card (x1, x4, x8 and x16) should work if PRSNT is implemented properly on the installed PCIe card.
