Installation
3-1 Static-Sensitive Devices
Electrostatic Discharge (ESD) can damage electronic components. To avoid dam-
aging your add-on card, it is important to handle it very carefully. The following
measures are generally su󰀩cient to protect your equipment from ESD.
Precautions
• Use a grounded wrist strap designed to prevent static discharge.
• Touch a grounded metal object before removing the add-on card from the
antistatic bag.
• Handle the add-on card by its edges only; do not touch its components or
peripheral chips.
• Put the add-on card back into the antistatic bags when not in use.
• For grounding purposes, make sure that your system chassis provides excel-
lent conductivity between the power supply, the case, the mounting fasteners,
and the add-on card.
Unpacking
The add-on card is shipped in antistatic packaging to avoid static damage. When
unpacking your component or your system, make sure that you are static protected.
Note: To avoid damaging your components and to ensure proper installa-
tion, be sure to always connect the power cord last, and always remove it
before adding, removing or changing any hardware components.

3-2 Before Installation
To install the add-on card properly, be sure to follow the instructions below.
1. Power down the system.
2. Remove the power cord from the wall socket.
3. Use industry standard anti-static equipment (such as gloves or wrist strap)
and follow the instructions listed on page 3-1 to avoid damage caused by
ESD.
4. Familiarize yourself with the server, motherboard, and/or chassis documenta-
tion.
5. Conrm that your operating system includes the latest updates and hotxes.
3-3 Installing the Add-on Card
Follow the steps below to install the add-on card into your system.
1. Remove the server cover and, if necessary, set aside any screws for later
use.
2. Remove the add-on card slot cover. If the case requires a screw, place the
screw aside for later use.
3. Position the add-on card in the slot directly over the connector, and gently
push down on both sides of the card until it slides into the PCI connector.
4. Secure the add-on card to the chassis. If required, use the screw that you
previously removed.
5. Attach any necessary external cables to the add-on card.
6. Replace the chassis cover.
7. Plug the power cord into the wall socket, and power up the system.

3-4 Installing Drivers for Windows
Follow the steps below to install the drivers needed for your Windows OS support.
The controller comes with a driver on the CD-ROM CDR-NIC.
1. Run the CDR-NIC. (If you do not have a product CD-ROM, download drivers
from the Supermicro Support Website and then transfer them to your system.)
2. When the SUPERMICRO window appears, click on the computer icon next to
the product model.
Note: If the FOUND NEW HARDWARE WIZARD screen displays on your
system, click CANCEL.
3. Click on INSTALL DRIVERS AND SOFTWARE.
4. Follow the prompts to complete the installation.
