1 Preface
1.1 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.

1.2 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.

1.3 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.

2 Product Information
The Gen 4 PCIe SDS-3U-4a contains options for Dual or Single-Socket AMD EPYC™ 7003 Series Processors and provides a feature packed server
platform for GPU or FPGA accelerated computing, U.2/U.3 NVMe storage and the most native PCIe Gen 4 x16 slots available on the market. This
functionality is delivered in a size efficient edge ready rugged chassis with 3U height and 20” depth. This allows the edge optimized server to
stand alone as a hyperconverged PCIe Gen 4 server or form the core CPU and memory resources for a scale-out, rack level, expandable or
composable solution in the shallowest available racks. The SDS-3U-4a features up to 7 PCIe Gen 4 x16 slots, and 16 SATA/SAS/NVMe drives. The
server supports up to 2TB of memory per CPU socket and a resource expanded BIOS for scale-out device enumeration and large memory
mapped I/O used for GPUs and accelerators.

5 Storage Drive Installation
5.1 Remove Drive Carrier
Hold the front handle and press the lever (from right to left motion) using your thumb while gently pulling the carrier out.
Place the drive carrier on a flat sturdy surface. Remove the two mounting screws on both sides.
Dismount the front handle to access the drive trays.
Press the eject button, grasp the handle, and gently pull the drive tray out.

One Stop Systems
OSS-SDS-3U-4A 18
5.2 Install Storage Drive
Place the hard drive tray on a flat, stable surface such as a desk, table, or work bench. Slide the hard drive into the tray with the gold-connector
facing upward, see photos below.
Carefully align the mounting holes between the hard drive and the tray. Secure the hard drive using all four of the screws.
Insert the drive tray into its bay vertically, keeping the carrier oriented so that the release button is on the bottom. Using the thumb, push
against the lower part of the hard drive handle. Push the hard drive into the hard drive bay as illustrated below, until the hard drive clicks into
the locked position.

6 Drive Slot & LINK Status LEDs
In the SDS unit, there are two Drive Packs installed. A drive pack is a single removal container that can accommodate from single to eight
storage drives. Each drive pack has 8 drive slots. A drive slot is an individual slot where the storage drive is physical inserted or installed.
The following photo represents the LINK STATUS LED of the controller card (visible and accessible from the back of card
bracket) when drive slots are occupied with storage devices.
•Slots are numbered 1 to 8, from left to right.
•On both “Drive Packs # 1 and 2”, the storage drive slots 2, 4, 6 and 8 are connected to the LINK STATUS LED.
•When drives are present in those slots, the associated bracket LINK STATUS LEDs will illuminate.
Drive Pack #1, occupied with 8 storage devices, LINK STATUS LEDs 0, 1, 2 and 3 are illuminated as solid green.
Drive Pack #2, occupied with 8 storage devices, LINK STATUS LEDs 4, 5, 6 and 7 are illuminated as solid green.

One Stop Systems
OSS-SDS-3U-4A 20
Photos below show individual drive slot on Drive Pack # 1 and their corresponding LINK STATUS LED.
Drive Pack #1:
•Drive slot 2 is tied to LINK STATUS LED 0
•Drive slot 4 is tied to LINK STATUS LED 1
•Drive slot 6 is tied to LINK STATUS LED 2
•Drive slot 8 is tied to LINK STATUS LED 3
Drive Pack# 1, storage drive slots 1, 3, 5 and 7 are not connected to the LINK STATUS LED. No LINK STATUS LED associated with
these drive slots will illuminate when drive is present except the LED located on the front
