Preface
About this User's Guide
This user's guide is written for system integrators, IT technicians and
knowledgeable end users. It provides information for the installation and use of the
AOC-S25G-m2S add-on card.
About this Add-on Card
The Supermicro AOC-S25G-m2S is a leading edge 25GbE controller. Based on the
Mellanox ConnectX®-4 Lx EN chipset with features such as VXLAN and NVGRE,
it is backward compatible with 10GbE networks and addresses bandwidth demand
from virtualized infrastructures in data centers or cloud deployments. It supports the
RoCE specication with CPU ofoad, delivering low-latency and high-performance
over Ethernet networks. Supermicro® Asset Management and thermal detection
give an extra layer of controller health management and peace of mind. The
Supermicro AOC-S25G-m2S high performance 25GbE adapter solution is an excel-
lent choice to enhance network connectivity in data centers and enterprise environ-
ments. For more information regarding product support or updates, please refer to

SFP28 (SFP1/SFP2) Connectors
Two small form-factor pluggable (SFP28) optical transceiver connectors (SFP1/
SFP2) are located on the add-on card. These SFP28 ports provide Ethernet up to
25GbE network connections. See the layout below for the locations.
SFP28 (SFP1/SFP2) Link/Activity LED Indicators
Two LAN Link/Activity LED indicators are located at PORT1 LED and PORT2
LED on the add-on card. PORT1 LED is used for the SFP28 SFP1 connector, and
PORT2 LED, for SFP28 SFP2 connector. See the table below for the LED states.

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.

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 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 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 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.
