General Safety Precautions; Electrostatic Discharge (Esd) Precautions - NETGEAR RNDU4000 Hardware Manual

General Safety Precautions

Follow these rules to ensure general safety:
• Keep the area around the ReadyNAS clean and free of clutter.
• See the technical specifications in this manual for details about your specific ReadyNAS
Ultra unit.
• Replace the on-board battery only with the same battery or an equivalent type of battery
recommended by the manufacturer. Dispose of used batteries according to the
manufacturer's instructions.
DANGER:
Installing the battery upside down reverses its polarities and creates a
danger of explosion.
• Main board replaceable soldered-in fuses: Only trained service technicians can replace
the self-resetting PTC (positive temperature coefficient) fuses on the main board, using
only new fuses that are the same as or equivalent to the ones being replaced. Contact
Technical Support for details and support.

Electrostatic Discharge (ESD) 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 your computer chassis provides excellent
conductivity between the power supply, the case, the mounting fasteners and the main
board.
