The Supermicro® AOC-S25G-i2S is a robust 25GbE solution based on Intel®
XXV710. This add-on card with existing 10GbE networking infrastructures is capable
of doubling available bandwidth. The 25GbE bandwidth enables rapid networking
deployment in data centers and corporate environments. In addition, Supermicro
Asset Management and thermal detection provide an extra layer of controller health
management. For customers who require fast and reliable networking demands,
AOC-S25G-i2S is an excellent choice to enhance network connectivity and stabil-
ity in the market.
An Important Note to the User
All images and layouts shown in this user's guide are based upon the latest PCB
revision available at the time of publishing. The card you have received may or may
not look exactly the same as the graphics shown in this user's guide.

2-4 NC-SI Header & PCI-E 3.0 x8 Golden Finger
NC-SI Header
A Network-Controller Sideband Interface (NC-SI) header is located at JNCSI1 on
the add-on card. Connect an appropriate cable from this header to a motherboard
to provide the out-of-band (sideband) connection between the onboard Baseboard
Management Controller (BMC) and a Network Interface Controller (NIC) for remote
management. For the network sideband interface to work properly, you will need
to use a motherboard that supports NC-SI and also need to have a special cable.
Please contact Supermicro at www.supermicro.com to purchase the cable for this
header. See the layout below for the location of the JNCSI1 header.
PCI-E 3.0 x8 Golden Finger
A PCI-E 3.0 x8 Golden Finger is located at JGF1 on the add-on card. Insert this
connector into a PCI-E 3.0 x8 slot on a motherboard to use this add-on card. See
the layout below for the location.
1. NS-CI Header
2. PCI-E 3.0 x8 Golden
Finger
System Management Bus (SMB) Header
The SMB header (J9) is used to monitor critical parameters on the add-on card to
enhance overall system performance. See the layout below for the location.

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 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
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 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. Unplug the power cord.
3. Use industry standard anti-static equipment (such as gloves or wrist strap)
and follow the precautions 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 any, 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.

3-5 Installing Drivers on 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 version and conguration of the installed kernel sources. If you
have just recompiled the kernel, reboot the system at this time.
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:
tar xzvf i40e-x.x.x.tar.gz
3. Change to the driver src directory:
cd i40e-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.
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
