Preface
Advisories
Five types of advisories are used throughout this manual to provide helpful information, or to alert you to the potential for hardware damage
or personal injury.
Disclaimer: We have attempted to identify most situations that may pose a danger, warning, or caution condition in this manual. However, One
Stop Systems does not claim to have covered all situations that might require the use of a Caution, Warning, or Danger indicator.

Safety Instructions
Always use caution when servicing any electrical component. Before handling the One Stop Systems Expansion chassis, read the following
instructions and safety guidelines to prevent damage to the product and to ensure your own personal safety. Refer to the “Advisories” section
for advisory conventions used in this manual, including the distinction between Danger, Warning, Caution, Important, and Note.
Always use caution when handling/operating the computer. Only qualified, experienced, authorized electronics personnel should access the
interior of the computer and expansion chassis.
WARNING
Never modify or remove the radio frequency interference shielding from your workstation or expansion unit. To do so
may cause your installation to produce emissions that could interfere with other electronic equipment in the area of
your system.
When Working Inside a Computer
Before taking covers off a computer, perform the following steps:
Turn off the computer and any peripheral devices.
Disconnect the computer and peripheral power cords from their AC outlets or inlets in order to prevent electric shock or system board damage.
In addition, take note of these safety guidelines when appropriate:
To help avoid possible damage to systems boards, wait five seconds after turning off the computer before removing a component,
removing a system board, or disconnecting a peripheral device from the computer.
When you disconnect a cable, pull on its connector or on its strain-relief loop, not on the cable itself. Some cables have a connector
with locking tabs. If you are disconnecting this type of cable, press in on the locking tabs before disconnecting the cable. As you pull
connectors apart, keep them evenly aligned to avoid bending any connector pins. Also, before connecting a cable, make sure both
connectors are correctly oriented and aligned.
CAUTION
Do not attempt to service the system yourself except as explained in this manual. Follow installation instructions
closely.

Protecting Against Electrostatic Discharge
Electrostatic Discharge (ESD) Warning
Electrostatic Discharge (ESD) is the enemy of semiconductor devices. You should always take precautions to eliminate
any electrostatic charge from your body and clothing before touching any semiconductor device or card by using an
electrostatic wrist strap and/or rubber mat.
Static electricity can harm system boards. Perform service at an ESD workstation and follow proper ESD procedures to reduce the risk of
damage to components. One Stop Systems strongly encourages you to follow proper ESD procedures, which can include wrist straps and
smocks, when servicing equipment.
You can also take the following steps to prevent damage from electrostatic discharge (ESD):
When unpacking a static-sensitive component from its shipping carton, do not remove the component’s anti-static packaging material until you
are ready to install the component in a computer. Just before unwrapping the anti-static packaging, be sure you are at an ESD workstation or
are grounded.
When transporting a sensitive component, first place it in an anti-static container or packaging.
Handle all sensitive components at an ESD workstation. If possible, use anti-static floor pads and workbench pads.
Handle components and boards with care. Do not touch the components or contacts on a board. Hold a board by its edges or by its metal
mounting bracket.

1Introduction
1.1 General Specifications
The 2U EOS server revolutionizes the capabilities of homogenous systems containing tightly coupled processors, NVMe solid-state storage,
high-speed networking, and accelerator co-processing elements such as GP-GPUs and FPGAs. The 2U EOS contains two of the newest Intel
Scalable Processors and provides the widest BIOS compatibility with dense storage and accelerator expansion systems. This allows the highly
integrated server to stand alone or form the core CPU and memory resources for a scale-out, rack level, expandable solution. The EOS server
features two storage and I/O configurations providing up to six PCIe 3.0 x16 half-height slots or 24 U.2 NVMe drives. The server supports up to
4TB of memory and a resource expanded BIOS for scale-out device enumeration and large memory mapped I/O used for GP-GPUs and
accelerators
