Major Components

The following major components are installed on the AOC-2UR68G4-m2TS:

AOC-2UR68G4-m2TS Major Components

x16)

| Slot 3

Ports
There are two LAN ports (LAN1 and LAN2) located on the AOC-2UR68G4-m2TS add-on card. Connect a Direct Attach Copper Twin Axial cable or an LC Fiber-Optic cable to the ports to provide Gigabit Ethernet communication. Each connector has two ports. The SFP28 connector ports are for LAN1 and LAN2. Refer to the add-on card layout on pages 2-1 through 2-2 for the locations of the ports.

Connectors
SFP28 Port LEDs
There are two bi-colored LED indicators per port (Link and Activity). Please refer to the table below for LED color definition.

LAN Port LEDs

Jumpers

Explanation of Jumpers
To modify the operation of the add-on card, a jumper can be used to choose be- tween optional settings. A jumper creates shorts between two pins to change the function of the connector. See the add-on card layouts on pages 2-1 and 2-2 for the jumper locations.
Note: On two-pin jumpers, “Closed” means the jumper is on and “Open” means the jumper is off the pins.

Standby Power Enable
The 3.3V Standby Power Enable jumper, located at JP3, is used to turn on or turn off 3.3V standby power. To turn 3.3V standby power on, close pins 1-2 to enable NC-SI, BMC management, shared LAN1, and WoL (Wake-on-LAN) support during standby. Close pins 3-4 to turn 3.3V standby power off, which will also disable the connections to NC-SI, BMC, shared LAN1, and WoL during standby. The default setting is 3.3V Standby Off on pins 3-4. Refer to page 2-1 for JP3 location.
Warning: Please check with your local Supermicro FAE or contact Supermicro Technical Support before you change the JP3 jumper to en-able 3.3V Standby On. Staying in the standby state for a long period of time without the fan blowing air inside the chasis may cause the onboard Mellanox chipset to overheat.

Installation

Static-Sensitive Devices
Electrostatic Discharge (ESD) can damage electronic com ponents. To avoid dam- aging 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 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 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.

Before Installation
To install the add-on card properly, be sure to follow the instructions below.

Power down the system.
Remove the power cord from the wall socket.
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.
Familiarize yourself with the server, motherboard, and/or chassis documenta-tion.
Confirm that your operating system includes the latest updates and hotfixes.

Installing the Add-on Card
Follow the steps below to install the add-on card into your system.

Remove the server cover and, if necessary, set aside any screws for later use.
Remove the add-on card slot cover. If the case requires a screw, place the screw aside for later use.
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.
Secure the add-on card to the chassis. If required, use the screw that you previously removed.
Attach any necessary external cables to the add-on card.
Replace the chassis cover.
Plug the power cord into the wall socket, and power up the system.

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.

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.)
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.

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

Installing Drivers (for Mellanox® ConnectX-6)
Use the procedures below to install the driver for the AOC-2UR68G4-m2TS add-on card on both Linux and Windows.

Linux Drivers

Use the following procedures to install the 25GbE driver on the Linux (Red-Hat/ CentOS) operating system.
We recommend downloading the latest Mellanox Driver directly from the Mellanox website: https://mellanox.com/products/infiniband-drivers/linux/mlnx_ofed.
Download and extract /untar the MLNX_OFED***.tgz package.
Change to the appropriate directory where your newly extracted package is located.
Install the driver by entering the following commands: ./mlnxofedinstall ./ mlnxofedinstall
This installs the Linux drivers to your system. You might be prompted to install kernel dependencies for Linux, in which case you would need to follow on-screen instructions.

Windows Drivers
Use the following procedures to install a 25GbE driver on the Windows operating system.

We recommend that you download the latest Mellanox Driver directly from the Mellanox website: https://mellanox.com/products/adapter-software/ethernet/windows/winof-2.
Once the driver is downloaded, run the .exe file to install the driver
