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.
