Frequently Asked Questions - AOC-CTG-i1S Supermicro

What operating systems are supported by the AOC-CTG-i1S?

The AOC-CTG-i1S supports Windows Server (2012 R2, 2016, 2019, 2022), Linux (various distributions with kernel 3.10+), and VMware ESXi (6.0 and later).

Does the card support Wake-on-LAN?

Yes, the AOC-CTG-i1S supports Wake-on-LAN (WoL) when connected to a compatible motherboard and configured in the OS.

Can I use this card in a standard desktop PC?

Yes, if the PC has an available PCIe x8 or x16 slot. The card is low-profile, so it fits in smaller cases with included bracket.

What cable type is required for 10GbE operation?

For 10 Gbps speeds, use Cat 6a or Cat 7 Ethernet cables with RJ45 connectors. Cat 5e may work at reduced distances.

How do I install the drivers?

Drivers can be downloaded from Supermicro's support site. For Windows, run the installer; for Linux, compile from source or use built-in kernel support.

What is the maximum cable length for 10GBase-T?

With Cat 6a or better cabling, the maximum distance is 100 meters (328 feet) for 10GBASE-T.

Does the card support SR-IOV?

Yes, the Intel X550 controller supports SR-IOV (Single Root I/O Virtualization) for efficient virtualization.

Is the AOC-CTG-i1S compatible with Supermicro motherboards only?

No, it is a standard PCIe add-in card and can be used in any compatible system from any brand.

What do I do if the card is not detected?

Check that the card is firmly seated in the PCIe slot, update motherboard BIOS, and install the latest drivers. If using Linux, verify kernel module ixgbe is loaded.

Can I use both ports independently?

Yes, each of the two 10GbE ports operates independently and can be assigned separate IP addresses or used for failover/bonding.

Installation

3-1 Static-Sensitive Devices

Electrostatic Discharge (ESD) can damage electronic components. To avoid damaging your add-on card, it is important to handle it very carefully. The following measures are generally sufficient 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 your system, make sure that the person handling it is static protected.

Warning: 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.

3-2 Add-On Card Brackets

The add-on card ships with a PCB bracket that is pre-installed at the factory. For 1U systems, an I/O bracket is also pre-installed on the card. For 2U systems, the I/O bracket is bundled with the card and must be installed by the customer. See the drawings below for bracket details.

BKT-0056L (Factory installed MicroLP PCB bracket) For 2U System BKT-0058L (Customer installed I/O bracket for 2U system) For 1U System BKT-0057L (Factory installed I/O bracket)

3-3 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 documentation.
5. Confirm that your operating system includes the latest updates and hotfixes.

3-4 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.

3-5 Installing the Windows Operating System

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.

1. Click on INSTALL DRIVERS AND SOFTWARE.
2. Follow the prompts to complete the installation.

3-6 Installing the Linux Operating System

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

Build a Binary RPM Package

1. Run 'rpmbuild -tb '
2. Replace with the specific filename of the driver.

Note: For the build to work properly, the current running kernel MUST match the version and configuration of the installed kernel sources. If you have just recompiled the kernel, reboot the system at this time.

3-7 Building the Driver Manually

Follow the instructions below to build the driver manually.

1. Move the base driver tar file to the directory of your choice. For example

/home/username/ixgbe

or

/usr/local/src/ixgbe

1. Untar/unzip archive, where is the version number for the driver tar file:

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

1. Change to the driver src directory, where is the version number for the driver tar:

cd ixgbe-x.x.x/src/

1. 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 file included in the driver tar.

Note: IXGBE_NO_LRO is a compile time flag. The user can enable it at compile time to remove support for LRO from the driver. The flag is used by adding CFLAGS_EXTRA=-"DIXGBE_NO_LRO" to the make file when it's being compiled.

make CFLAGS_EXTRA="-DIXGBE_NO_LRO" install

1. Load the module:

For kernel 2.6.x, use the modprobe command:

modprobe ixgbe =

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

insmod /lib/modules//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

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

ifconfig ethx netmask

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

ping
