Installation

3.1 Static-Sensitive Devices

Electrostatic Discharge (ESD) can damage electronic com ponents. To avoid damaging your
add-on card, it is important to handle it very carefully. The following measures are generally

suf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 excellent conduc-

tivity 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 system, make sure that you are static protected.

Note: To avoid damaging your components and to ensure proper installation, be sure
to always connect the power cord last, and always remove it before adding, removing
or changing any hardware components.

17

AOC-S40G-i1Q/i2Q User's Guide

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 precautions listed on page 17 to avoid damage caused by ESD.

4. Familiarize yourself with the server, motherboard, and/or chassis documentation.

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 in the power cord and power up the system.

18

Chapter 3: Installation

3.4 Installing the Add-On Card

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: The graphic below is from the AOC-SG40G-i2Q card. If you are using an i1Q
card, your window may have some slight differences.

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.

19

AOC-S40G-i1Q/i2Q User's Guide

3.5 Installing the Drivers in Linux

Follow the steps below to install the driver to a Linux system.

Build a Binary RPM Package

1. Run ‘rpmbuild -tb <lename.tar.gz>’

2. Replace <lename.tar.gz> with the specic lename of the driver.

Note: For the build to work properly, the current running kernel MUST match the ver-

sion and conguration of the installed kernel sources. If you have just recompiled the

kernel, reboot the system at this time.

3.6 Building the Driver Manually

Follow the instructions below to build the driver manually.

1. Move the base driver tar le to the directory of your choice. For example:

/home/username/ixgbe

or

/usr/local/src/ixgbe

2. Untar/unzip archive, where <x.x.x> is the version number for the driver tar le:

tar zxf ixgbe-x.x.x.tar.gz

3. Change to the driver src directory, where <x.x.x> is the version number for the driver tar:

cd ixgbe-x.x.x/src/

4. Compile the driver module:

make install

The binary will be installed as:

/lib/modules/[KERNEL_VERSION]/kernel/drivers/net/ixgbe/ixgbe.[k]o

The install locations listed above are the default locations. They might not be correct for

certain Linux distributions. For more information, see the ldistrib.txt le included in the

driver tar.

20

Chapter 3: Installation

Note: IXGBE_NO_LRO is a compile time ag. The user can enable it at compile time to
remove support for LRO from the driver. The ag is used by adding CFLAGS_EXTRA=­”DIXGBE_NO_LRO” to the make le when it’s being compiled.

make CFLAGS_EXTRA=”-DIXGBE_NO_LRO” install

5. Load the module:

For kernel 2.6.x, use the modprobe command:

modprobe ixgbe <parameter>=<value>

For 2.6 kernels, the insmod command can be used if the full path to the driver module is

specied. For example:

insmod /lib/modules/<KERNEL VERSION>/kernel/drivers/net/ixgbe/

ixgbe.ko

In addition, when using 2.6-based kernels, make sure that older ixgbe drivers are removed
from the kernel before loading the new module. To do this, use:

rmmod ixgbe; modprobe ixgbe

6. Assign an IP address to the interface by entering the following, where x is the interface
number:

ifcong ethx <IP_address> netmask <netmask>

7. Verify that the interface works. Enter the following, where <IP_address> is the IP
address for another machine on the same subnet as the interface that is being tested:

ping <IP_address>

3.7 Returning Merchandise for Service

A receipt or copy of your invoice marked with the date of purchase is required before any
warranty service will be rendered. You can obtain service by calling your vendor for a
Returned Merchandise Authorization (RMA) number. When returning the motherboard to
the manufacturer, the RMA number should be prominently displayed on the outside of the
shipping carton, and the shipping package is mailed prepaid or hand carried. Shipping and
handling charges will be applied for all orders that must be mailed when service is complete.
For faster service, you can also request a RMA authorization online (http://www.supermicro.
com/RmaForm/).

This warranty only covers normal consumer use and does not cover damages incurred in
shipping or from failure due to the alternation, misuse, abuse or improper maintenance of
products.

During the warranty period, contact your distributor rst for any product problems.
