NETGEAR ReadyNAS OS 6 Rack-Mount Storage Systems Electrostatic Discharge Precautions Electrostatic discharge (ESD) is generated by two objects with different electrical charges coming into contact with each other. An electrical discharge is created to neutralize this difference, which can damage electronic components and printed circuit boards. The following measures are generally sufficient to neutralize this difference before contact is made to protect your equipment from ESD: • Use a grounded wrist strap designed to prevent static discharge. • Keep all components and printed circuit boards (PCBs) in their antistatic bags until ready for use. • Touch a grounded metal object before removing the board from the antistatic bag. • Do not let components or PCBs come into contact with your clothing, which might retain a charge even if you are wearing a wrist strap. • Handle a board by its edges only; do not touch its components, peripheral chips, memory modules, or contacts. • When handling chips or modules, avoid touching their pins. • Put the main board and peripherals back into their antistatic bags when not in use. • For grounding purposes, make sure that your computer chassis provides excellent conductivity between the power supply, the case, the mounting fasteners, and the main board. • After accessing the inside of the system, close the system back up and secure it to the rack unit with the retention screws after ensuring that all connections were made. Rack-Mount Precautions Follow these rack-mount precautions: • Ensure that the leveling jacks on the bottom of the rack are fully extended to the floor with the full weight of the rack resting on them. • In single-rack installations, make sure that stabilizers are attached to the rack. In multiple-rack installations, make sure that the racks are coupled together. • Always make sure that the rack is stable before extending a component from the rack. • Extend only one component at a time; extending two or more simultaneously might cause the rack to become unstable. • Determine the placement of each component in the rack before you install the rails. • Install the heaviest components on the bottom of the rack first, and then work up. • Use a regulating uninterruptible power supply (UPS) to protect the ReadyNAS from power surges and voltage spikes and to keep your system operating in case of a power failure. • Allow any hot-plug drives and power supply modules to cool before touching them. • Always keep the rack's front door and all panels and components on the servers closed when not servicing them to maintain proper cooling.

Electrostatic Discharge Precautions
Electrostatic discharge (ESD) is generated by two objects with different
electrical charges coming
into contact with each other. An electrical
discharge is created to neutralize this difference, which can damage
electronic components and printed circuit boards. The following measures
are generally sufficient to neutralize this difference before contact is made
to protect your equipment from ESD:
•
Use a grounded wrist strap designed to prevent static discharge.
•
Keep all components and printed circuit boards (PCBs) in their antistatic bags until ready
for use.
•
Touch a grounded metal object before removing the board from the antistatic bag.
•
Do not let components or PCBs come into contact with your clothing, which might retain a
charge even if you are wearing a wrist strap.
•
Handle a board by its edges only; do not touch its components, peripheral chips, memory
modules, or contacts.
•
When handling chips or modules, avoid touching their pins.
•
Put the main board and peripherals back into their antistatic bags when not in use.
•
For grounding purposes, make sure that your computer chassis provides excellent
conductivity between the power supply, the case, the mounting fasteners, and the main
board.
•
After accessing the inside of the system, close the system back up and secure it to the
rack unit with the retention screws after ensuring that all connections were made.
Rack-Mount Precautions
Follow these rack-mount precautions:
•
Ensure that the leveling jacks on the bottom of the rack are fully extended to the floor with
the full weight of the rack resting on them.
•
In single-rack installations, make sure that stabilizers are attached to the rack. In
multiple-rack installations, make sure that the racks are coupled together.
•
Always make sure that the rack is stable before extending a component from the rack.
•
Extend only one component at a time; extending two or more simultaneously might cause
the rack to become unstable.
•
Determine the placement of each component in the rack
before
you install the rails.
•
Install the heaviest components on the bottom of the rack first, and then work up.
•
Use a regulating uninterruptible power supply (UPS) to protect the ReadyNAS from
power surges and voltage spikes and to keep your system operating in case of a power
failure.
•
Allow any hot-plug drives and power supply modules to cool before touching them.
•
Always keep the rack’s front door and all panels and components on the servers closed
when not servicing them to maintain proper cooling.
