EonStor A12U/A08U-G2421 Installation and Hardware Reference Manual
Safety Precautions
Precautions and Instructions
• Prior to powering on the subsystem, ensure that the correct power range is being
used.
• The EonStor A12U and A08U subsystems come with eight (8) or twelve (12)
drive bays. Leaving any of these drive bays empty will seriously affect the
efficiency of the airflow within the enclosure, and will consequently lead to the
system overheating, which can cause irreparable damage.
• If a module fails, leave it in place until you have a replacement unit and you are
ready to replace it.
• Airflow Consideration: The subsystem requires an airflow clearance, especially
at the front and the rear side.
• Handle subsystem modules using the retention screws, extraction levers, and the
metal frames/faceplates. Avoid touching PCB boards and connector pins.
• To comply with safety, emission, or thermal requirements, none of the covers or
replaceable modules should be removed. Make sure that during operation, all
enclosure modules and covers are securely in place.
• Be sure that the rack cabinet that the subsystem chassis is to be installed provides
sufficient ventilation channels and airflow circulation around the subsystem.
• Provide a soft, clean surface to place your subsystem on before working on it.
Servicing on a rough surface may damage the exterior of the chassis.
• If it is necessary to transport the subsystem, repackage all disk drives separately.
If using the original package material, other replaceable modules can stay within
the enclosure.
ESD Precautions
Observe all conventional anti-ESD methods while handling system modules. The use
of a grounded wrist strap and an anti-static work pad are recommended. Avoid dust
or debris in your work area.
