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. OSS strongly encourages 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.

2.1 Tools Required for Installation
To complete the installation of the OSS product you will need a Phillips-head screwdriver and ESD wrist strap to prevent electrostatic discharge.
The following steps will guide you through the installation of your OSS Expansion System.
CAUTION
Hardware installation shall be performed only by qualified service personnel.
Electrostatic Discharge (ESD) Warning
All add-in cards are susceptible to electrostatic discharge. When moving cards, it is best to carry the cards in anti-static
packaging. If you need to set a circuit card down, be sure to place it inside or on top of an anti-static surface. For more
information, see “Protecting Against Electrostatic Discharge” in the Preface.
WARNING
High voltages are present inside the expansion chassis when the unit’s power cord is plugged into an electrical outlet.
Disconnect the power cord from the AC outlet before removing the enclosure cover. Turning the system power off at the
power on/off switch does not remove power to components. High voltage is still present.
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.

2.5 Install Host Interface card
Begin the installation of your Host interface card by first powering down your computer.
The Host interface card is a “half-height,” x8-capable PCIe card mounted to a “full-height” bracket as shown below.
For low profile case applications, you may need to change the mounting bracket to the low profile bracket that shipped with your system. This
is done by removing the screws that hold the card to the bracket. Make sure you are using proper ESD procedures when completing this action.
WARNING
YOU MUST ONLY INSTALL THE PCIe HOST CARD INTO A PCI EXPRESS SLOT.
Only use an Interface card WITH bracket. This will ensure that your PCIe host card can only be inserted into a PCIe slot.
Although PCI Express cards without brackets may fit into conventional PCI slots, you run the risk of damaging the PCI
Express host card if you insert it into a PCI slot.
Once the host computer is off and all power cords are disconnected from the AC outlet, remove the cover.
Check the red Dipswitch (SW1) on the Host interface card, make sure it is set to OFF= HOST.
Check the SW2 Dipswitch, both toggle switches are set to OFF position (x8).
If the host card is set to expansion mode (ON=EXP), it may not work properly.

Insert the Host interface card into a vacant x8 (or x16) PCIe slot by gently pushing the card until it is firmly seated. Then secure the card into
the slot with a mounting screw.
To utilize the maximum bandwidth, install the OSS Host interface card into a Gen3 x8 lane slot or Gen2 x8 lane slot.
2.5.1 Computer PCIe slots to use
You must plug in the OSS Host interface card to the following slots:
1. X16 slot @ x16 mode
2. X16 slot @ x8 mode
3. X8 slot @ x8 mode

2.6 Install PCIe Cards
It is highly recommended to install third party PCI-E cards / High Power PCIe cards after you have verified and tested that the OSS expansion
chassis is functional.
When installing third Party PCIe card, start with one card first just to see if there are any software and/or hardware issues or incompatibility
problems that may occur. This way you can troubleshoot the problem more easily and efficiently. If everything works well with one card and
there are no configuration issues, you can proceed with the installation of the remaining cards.
Remove slot covers and install PCIe cards.
Make sure that all cards are fully seated in their PCIe card slots. When correctly seated, there will be a firm resistance when you pull up gently
on the card. To keep the cards in place, secure them in the enclosure with their retaining screws. After securing the cards verify that they do
not touch each other.
Some card manufacturers recommend that you install their software driver prior to installing the card. If this is the case, be sure to install the
card driver before connecting EB2200 to the computer.
Always refer to or read “3rd party manufacturer installation guide” for further instructions

2.6.1 OSS PCIe slot
The OSS EB2200 expansion chassis has a x8 (electrically), x16 (mechanically) slot. All three slots are compatible with x1, x2, x4, x8 and x16
PCIe cards.
It is a x16 connector but it is only electrically wired as a x8 lane.
Slots have two main properties:
• Physical size
• Electrical connectivity
The physical size determines the size of the slot on the motherboard. You can physically plug a x8 card into a x16 slot. The electrical
connectivity determines the number of "lanes" actually wired up. Less lanes means less potential data transfer speed. All 3 slots are
compatible with x1, x2, x8 and x16 cards.
Slot 0 accepts all types of PCIe cards x1, x2, x4, x8 or x16 (mechanical).
Slot 1 accepts all types of PCIe cards x1, x2, x4, x8 or x16 (mechanical).
Slot 2 accepts all types of PCIe cards x1, x2, x4, x8 or x16 (mechanical).
Slot 3 is designated slot for Expansion interface card.
NOTE
If you plug in a x16 PCIe card, it will run at x8 because the OSS PCIe slot is electrically wired as x8 lane.
