Chapter 4. System Safety
4.1 Electrical Safety Precautions
Basic electrical safety precautions should be followed to protect yourself from harm and the
R423-E3 from damage:
 Be aware of the locations of the power on/off switch on the chassis as well as the
room's 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.
 Power should always be disconnected from the system when removing or
installing main system components, such as the serverboard, memory modules and
add-on cards. When disconnecting power, you should first power down the operating
system first and then unplug the power cords. The unit has more than one power
supply cord. Disconnect two power supply cords before servicing to avoid electrical
shock.

When working around exposed electrical circuits, another person who is familiar with
the power-off controls should be 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.

The power supply power cords must include a grounding plug and must be
plugged into grounded electrical outlets.
 This product may be connected to an IT power system. In all cases, make sure that the
unit is also reliably connected to Earth (ground).

Serverboard Battery: CAUTION - There is a danger of explosion if the onboard
CR2032 battery is installed upside down, which will reverse its polarities (see Figure
4-1). This battery must be replaced only with the same or an equivalent type
recommended by the manufacturer. Dispose of used batteries according to the
manufacturer's instructions.
 Mainboard replaceable soldered-in fuses: Self-resetting PTC (Positive Temperature
Coefficient) fuses on the mainboard must be replaced by trained service technicians
only. The new fuse must be the same or equivalent as the one replaced. Contact
technical support for details and support.
