General Safety Precautions

ReadyNAS Desktop Storage Systems

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.
