Electrical Safety Precautions
Follow basic electrical safety precautions to protect yourself from harm and the ReadyNAS from damage:
• Be aware of the locations of the power on/off switch on the chassis as well as the rooms emergency
power-off switch, disconnection switch, or electrical outlet. If an electrical accident occurs, you can then
quickly remove power from the system.
• Do not work alone when working with high-voltage components.
• Always disconnect power from the system when removing or installing main system components, such
as the main board or memory modules. When disconnecting power, first power down the system with
the operating system and then unplug the power cords of all the power supply storage systems in the
system.
• When working around exposed electrical circuits, ensure that another person who is familiar with the
power-off controls is nearby to switch off the power if necessary.
• Use only one hand when working with powered-on electrical equipment. This is to avoid making a
complete circuit, which will cause electrical shock. Use extreme caution when using metal tools, which
can easily damage any electrical components or circuit boards they come into contact with.
• Do not use mats designed to decrease static electrical discharge as protection from electrical shock.
Instead, use rubber mats that have been specifically designed as electrical insulators.
• Use only power supply cords that include a grounding plug and plug them into grounded electrical
outlets.
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 storage systems.
• 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.
Installing the battery upside down reverses its polarities and creates a danger of
explosion.
Note
• Only trained service technicians can replace the soldered-in 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 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:
