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 managing 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 around 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 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.
Manage 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.

OSS-EXS-C48 19
Gently pull the top cover then lift it up.
3.3 Verify SW1 Dipswitch Setting
Check the SW1 dipswitch settings on the OSS-528 BOARD. Make sure the switches
are set correctly. Refer to the photos below for the correct settings.
3.4 Connect Power Cords
3.4.1 Plug-in the power cords to the storage expansion unit.
AC Power Supply: Plugin the AC power cords to the power supply receptacles, see photos
below.

One Stop Systems
OSS-EXS-C48 20
DC Power Supply: Use a DC power cables. The DC power cables are not included with the
unit.
Mount the DC power cable to each power supply.
3.4.2 Plug in power cords to a PDU Power Strip
Connect the other end of the power cords to a PDU (Power Distribution Unit) power
strip. It is highly recommended to use PDU with surge protection. Photo below is an
example of PDU power strip.
Turn ON the PDU power strip, upon switching ON, the LEDS on the power supply will
illuminate from solid amber to blinking green.
